PART I

Introduction to ChatGPT

Trang 13

CHAPTER 1

What Is ChatGPT ?

Natural language processing (NLP) is a branch of artificial intelligence that aims to enable computers to understand and interact with human language In this field, ChatGPT is a pre-trained natural language

processing model that has become very popular in recent months

(The GPT stands for “generative pre-trained transformer.”)

Using sophisticated artificial neural networks, ChatGPT is capable

of generating coherent and relevant texts, making it a valuable tool for a variety of applications, such as automatic response, content generation, and virtual assistance

In this chapter, we will explain in more detail what ChatGPT is and its areas of application

Definition of ChatGPT

Let’s imagine that you are using a computer program (called a chatbot) to

order food online You start the conversation by asking, “What vegetarian dishes are available?”

The chatbot (i.e., the computer program you are using to interact)

in this case is ChatGPT. The language model of ChatGPT analyzes your question, taking into account the context of the conversation (i.e., ordering food online), and generates a response using the information available

to it The response may be something like, “We have several options for vegetarian dishes, such as vegetable pasta, tofu curry, and roasted vegetable pizzas What would you like?”

Trang 14

The response generated by ChatGPT is based on a thorough analysis

of the previous text data it learned from your previous questions It also uses advanced natural language processing techniques to understand the meaning of your question and respond appropriately

In summary, ChatGPT uses a pre-trained generative language model

to understand user questions, consider context, and generate accurate and relevant conversational responses

ChatGPT History

ChatGPT is a relatively new natural language processing system, which was developed and published by OpenAI in 2019 However, its development relies on several major advances in the field of natural language processing that have been made over the last few decades

AI-based language models, like those used by ChatGPT, have been constantly evolving since the 2000s First-generation language models were developed from traditional statistical techniques such as hidden Markov models, while second-generation models introduced deep

learning techniques such as convolutional and recurrent neural networks.However, the development of ChatGPT was made possible by major advances in the training of large-scale language models, which allowed AI researchers to create language models based on billions of words of text Large-scale language models were made possible by improvements in computing power, as well as the existence of vast sets of publicly accessible text data, thanks to the Internet

Today, ChatGPT continues to evolve and improve through training on even larger datasets and exploration of new AI techniques

Trang 15

Versions of ChatGPT

There have been several versions of ChatGPT, each with improvements and additional features Here is a list of the most well-known versions:

• GPT-1: Released in 2018, GPT-1 was the first text

generation model in the GPT series

• GPT-2: Released in 2019, GPT-2 was an improved

version of GPT-1 with 1.5 billion parameters It was

famous for its highly convincing text generation

capabilities but also raised concerns about

disinformation

• GPT-3: Released in 2020, GPT-3 is the most recent and

advanced version of the GPT series with 175 billion

parameters It has been hailed for its ability to generate

even more natural text and perform a variety of natural

language processing tasks

• GPT-4: Released in 2023, OpenAI says, “GPT-4 can solve

difficult problems with greater accuracy, thanks to its

broader general knowledge and advanced reasoning

capabilities.”

Each of these versions has contributed to improving the quality and accuracy of automated text generation, allowing chatbots to communicate with users in a more natural and seamless manner

understand and translate users’ requests in real time

These examples are not exhaustive, but they illustrate the variety of domains in which ChatGPT can be used

Trang 18

Summary

In this chapter, you learned that ChatGPT is a powerful language model that has the ability to understand natural language input and generate coherent responses in a variety of contexts It was created using state-of-the-art machine learning techniques and is capable of answering a wide range of questions and engaging in human-like conversation As one of the most advanced language models available today, ChatGPT has the potential to revolutionize the way we interact with machines and help us solve complex problems more efficiently

In the next chapter, we will dive deeper into how ChatGPT works and explore some of the technical details behind its impressive capabilities

Trang 19

and generate text coherently We will also discuss the data used to train ChatGPT, as well as the advantages and limitations of this model We will discover how it acquires its linguistic skills while delivering task-specific performance.

Training and Personalization

The functioning of ChatGPT is based on two main steps

1 Training: ChatGPT is trained on a very large set of

textual data to learn language patterns and word

relationships This allows the model to understand

natural language and generate text in a consistent

and natural way

Trang 20

2 Personalization: Once the model has been trained, it

can be adapted to a specific task, such as answering

questions or generating text in a particular domain

This is done by providing the model with a training

dataset for the specific task so that it can adjust

its parameters and improve its performance on

that task

In simpler terms, ChatGPT learns to understand language by reading

a lot of texts, and then it is trained to perform specific tasks using training examples to improve its performance

1 During training, the ChatGPT neural network

analyzes language patterns in the training data

to learn to understand natural language It uses

these patterns to generate text in a coherent and

natural way

2 During customization, the ChatGPT neural

network is adjusted to perform a specific task,

such as answering questions or generating text in

a particular domain It uses training examples to

adjust its parameters and improve its performance

Trang 21

In conclusion, neural networks have revolutionized the field of

machine learning and data processing by allowing machines to learn from data and perform complex tasks In the context of ChatGPT, neural networks are used for generating natural language text

However, neural networks alone are not sufficient to enable ChatGPT

to generate high-quality text Therefore, advanced natural language

processing techniques are necessary to enable ChatGPT to produce natural, coherent, and relevant text The following section will therefore focus on the natural language processing techniques used by ChatGPT

Natural Language Processing Techniques Used by ChatGPT

ChatGPT uses several natural language processing techniques to

understand the language input by the user and generate text in response Here are a few examples:

• Tokenization: This technique involves dividing the text

into small units called tokens, which can be words,

characters, or subphrases ChatGPT uses a subword-

based tokenization technique, which allows it to better

understand the relationships between words

• Embeddings: Embeddings are vector representations

of words in a multidimensional space They allow

the meaning of words to be represented numerically,

which facilitates the automatic processing of

natural language ChatGPT uses transformer-based

embeddings, which are particularly well-suited for

language models

Trang 22

• Language models: Language models are statistical

models that predict the probability of a sequence of

words in a text ChatGPT uses a language model based

on a transformer neural network, which is capable of

generating text coherently and naturally

• Attention: Attention is a technique that allows language

models to focus on the most important parts of the text

based on context It allows ChatGPT to understand

the relationships between words in a sentence or

paragraph and then use this understanding to generate

text more accurately

The transformer is a technique used by ChatGPT to understand the context and meaning of words in a sentence It works by focusing on the most important parts of the sentence and ignoring less relevant parts, which reduces the number of parameters needed to train the model The transformer is therefore an effective method for understanding and generating natural language

“Attention is all you need” is a scientific article that introduced the transformer architecture, based on the attention mechanism, for natural language processing This approach revolutionized language models like ChatGPT, which uses a transformer to generate contextually appropriate responses in conversations By leveraging word relationships, ChatGPT can effectively and relevantly provide conversational responses

By combining these natural language processing techniques, ChatGPT

is able to understand language and generate text coherently and naturally, making it a powerful tool for many applications

Trang 23

The Data Used to Train ChatGPT

As previously stated, ChatGPT is trained on a large dataset of textual data

to learn language patterns and word relationships This enables the model

to understand natural language and generate text coherently and naturally.The data used to train ChatGPT is primarily natural language

text corpora such as books, news articles, social media posts, online

conversations, and more These corpora are often extensive and varied, allowing ChatGPT to comprehend and generate a wide range of texts

To effectively train the model, this data is often cleaned and

preprocessed to remove noise and inconsistencies The data is also often segmented into sentences or paragraphs so that the model can learn relationships between different elements in the sequence

Noise in the data refers to incorrect, incomplete, ambiguous,

redundant, or inconsistent data It can result from measurement errors, human errors in data entry, errors in the algorithms used to collect or process data, external interference, or other factors Noise can compromise data quality and lead to inaccurate or biased results when analyzing data Therefore, it is important to process and clean the data to minimize noise before use

It is important that the training data is representative of the variety of texts that ChatGPT will need to process in its application domain This will allow ChatGPT to understand the nuances of natural language and generate relevant and coherent responses

Here is an example of training ChatGPT using song text data:

1 Data collection: First, it is necessary to collect

song text data from different online sources This

data can be collected by using the Internet or by

downloading song data files

Trang 24

2 Data preprocessing: Song text data must be

cleaned and preprocessed before being used to

train ChatGPT. This may include removing special

characters, accents, numbers, HTML tags, and

URLs, as well as normalizing text to lowercase

3 Model training: Once the data has been cleaned,

it can be used to train a ChatGPT model using a

machine learning library such as TensorFlow or

PyTorch The model is trained using supervised

learning techniques where data is presented to

the model in the form of pairs of sentences and

corresponding responses

4 Model evaluation: After training, the ChatGPT

model is evaluated using test data to measure its

accuracy and efficiency

5 Model usage: Once the model is trained and

evaluated, it can be used to generate responses to

questions asked or input phrases provided This

can be useful in a variety of applications such as

chatbots, virtual assistants, and text generation

From this example, it is clear that training ChatGPT with real-world data can produce impressive results in terms of text generation This shows the immense potential of this technology for personalized content creation However, it is important to note that the use of ChatGPT must be responsible and ethical, as it can also be used to generate misleading or malicious content Therefore, it is important to establish regulations and standards to guide its use and prevent abuse

Trang 25

An Example of Training ChatGPT

An example of training where data is presented to the model in the form

of pairs of sentences and corresponding responses is training a chatbot designed to answer frequently asked questions about a product or service The training data could be pre-recorded pairs of questions and answers, such as the following:

Question: What is the monthly cost of your video streaming service? Answer: The monthly cost of our video streaming service is $10.

Question: How can I cancel my subscription?

Answer: To cancel your subscription, log in to your account and go to

the billing settings

The model would be trained from these data pairs by learning to associate questions with their corresponding answers When a user asks a question to the chatbot, the model would use natural language processing techniques to understand the question and find the most appropriate answer in its pre-trained knowledge base

The Advantages and Limitations of ChatGPT

ChatGPT has several advantages in natural language processing

• Flexibility: ChatGPT can generate text in different

application domains and languages, making it a very

versatile tool

• Continuous learning: ChatGPT can learn new

information and continuously improve as it is used,

thanks to its fine-tuning capability (see Chapter 4)

• Generation of coherent text: ChatGPT can generate

coherent and relevant text that resembles human-

written text, making it a useful tool for applications

such as automatic answering or content generation

Trang 26

However, ChatGPT also has some limitations.

• Lack of contextual understanding: While ChatGPT

can generate coherent text, it may still lack contextual

understanding and specific domain knowledge

• Bias risk: ChatGPT can reproduce biases or stereotypes

present in training data, leading to inappropriate

responses

• Need for large datasets: To achieve quality results,

ChatGPT requires large and varied training data, which

may require significant resources in terms of storage

and computation

Summary

Overall, ChatGPT is a powerful tool for natural language processing, but it

is important to be aware of its limitations and take them into account when using it

In the next chapter, we’ll go through some specific applications of ChatGPT

Trang 27

Chatbots and Virtual Assistants

Chatbots (also known as virtual assistants) are computer programs

designed to communicate with users through a chat interface They can

be used in a variety of fields, including customer service, marketing, and e-commerce ChatGPT can be used to power chatbots by providing them with relevant and consistent answers to user queries

Chatbots powered by ChatGPT use pre-trained language models to understand the natural language of users and generate appropriate responses Users can ask questions or make statements in natural language, and the chatbot will use the language models to understand the request and generate

an appropriate response Chatbots powered by ChatGPT can be customized

to meet the specific needs of the business or organization using them

Trang 28

Let’s look at an example of a chatbot for managing customer questions.Suppose an online sales company has set up a chatbot to help its customers When a customer logs on to the home page, the chatbot opens automatically and asks the customer how it can help If the customer has a question about a product, the chatbot can use ChatGPT to understand the question and respond accurately and relevantly.

For example, if a customer asks “What are the different payment methods accepted?” the chatbot can use ChatGPT to identify the question and respond with the payment methods accepted by the company The chatbot can also offer relevant product suggestions based on the questions asked by the customer

By using ChatGPT, the chatbot can provide a quick and accurate response to customers, improving the customer experience and

increasing overall business satisfaction Chatbots can be used to automate interactions with customers, answer frequently asked questions, guide users to relevant information, and even take orders or reservations

Chatbots can improve the customer experience by providing quick and accurate answers, while reducing costs

Machine Translation Apps

The interest of ChatGPT for automatic translation applications lies in its ability to understand and generate natural language in different languages Thanks to its neural network architecture, ChatGPT can be trained on large multilingual text corpora, which enables it to acquire an understanding

of the linguistic structure and semantic relationships between words in different languages This means that ChatGPT can be used to translate text from one language to another with relatively high accuracy, producing more natural results than traditional rule-based machine translation systems

Trang 29

Furthermore, ChatGPT can be fine-tuned to adapt to specific

automatic translation tasks, based on the application domain and target languages For example, a ChatGPT model can be trained to translate technical texts in a particular domain, such as medicine or engineering, using specific training data for that domain

With these capabilities, ChatGPT is increasingly being used to develop automatic translation systems for various applications, such as real-time translation on social media platforms, commercial document translation, and website content translation for multilingual sites

To use ChatGPT for automatic translation, pairs of sentences in

different languages are provided for model training Once trained, the model can predict the translation of a given sentence in another language using an understanding of the grammar and syntax of each language.For example, if one wants to translate the English sentence “I like to eat sushi” into French, ChatGPT can be used to predict the translation using a model trained with pairs of sentences in English and French The model can then predict that the translation of “I like to eat sushi” is “J’aime manger des sushis.”

Here are some examples of sentence pairs that could be used for training ChatGPT for the translation of “I like to eat sushi” into French:

• I like sushi ➤ J’aime le sushi

• Sushi is my favorite food ➤ Le sushi est mon plat

préféré

• I eat sushi every week ➤ Je mange du sushi chaque

semaine

• Have you ever tried sushi? ➤ As-tu déjà essayé le sushi?

• Sushi tastes delicious ➤ Le sushi a un gỏt délicieux

Trang 30

These sentence pairs enable ChatGPT to learn different ways of

translating the expression “I like to eat sushi” into French depending on the context With this training data, ChatGPT can produce more accurate and natural translations than traditional machine translation software, which often rely on pre-defined grammatical rules and lack the ability to understand the context and meaning of the sentence

Content Writing Apps

ChatGPT can be used for content writing applications because it can generate high-quality natural language text Unlike other rule- or template- based text generation methods, ChatGPT is capable of learning from large amounts of data and producing more natural and fluent responses By using a pre-trained model, it is possible to generate high-quality natural language text using fine-tuning techniques to adapt the model to specific tasks This can be particularly useful for businesses that need to produce content at scale, such as product descriptions, blog posts, reports, text summaries, etc By using ChatGPT for text generation, businesses can save time and costs while improving the quality and efficiency of their content production

Fine-tuning is a technique used to adjust a pre-trained language model to a specific dataset to produce specialized content For example, a journalist could use ChatGPT to generate article ideas or catchy headlines

by entering a brief description of the topic to cover The model could then generate several title or article angle suggestions from that description, allowing the journalist to save time and explore perspectives they may not have considered otherwise

Let’s use ChatGPT to write a few lines about “selling sushi.” The query given by the user to ChatGPT is “Give an example of content writing with

‘selling sushi.’” The response obtained could be, for example, the following:

Trang 31

ChatGPT: Selling sushi is a lucrative activity that is

growing in popularity worldwide Sushi-selling businesses can offer a variety of products, from traditional sushi

to contemporary creations, to satisfy the tastes of their customers To succeed in this field, it is essential to understand consumers' tastes and preferences, keep up with the latest trends, and provide superior quality products.The same query “Give an example of content writing with ‘selling sushi’” introduced a second time and sent to ChatGPT produces a new response expressed differently Here it is:

ChatGPT: Selling sushi is a growing market People are

increasingly interested in this traditional Japanese food, which is healthy, delicious, and easy to eat If you are looking to enter this market, you should consider creating

a sushi restaurant The keys to success are excellent quality ingredients, visually appealing presentation, and excellent customer service With a little effort, you can create a popular meeting place for sushi and Japanese food enthusiasts

Why is the second response generated by ChatGPT different, even though the query entered by the user is identical? Responses may vary depending on several factors

• It may depend on the context of the query, which can

influence how the model generates a response

• It may depend on the specific model used to generate

the response, as well as its level of training and the

quantity and quality of the training data used

Trang 32

• Responses can also be influenced by text generation

parameters such as the length of the generated

sequence, sampling temperature, and level of noise

Sampling temperature and noise level are parameters that affect text generation with language models such as ChatGPT. Sampling temperature controls the degree of diversity in word selection A higher temperature can allow for a greater variety of word choices, while a lower temperature can give more conservative responses

The noise level can affect the quality of text generation by adding unpredictability This can make responses more interesting and surprising, but it can also lead to less coherent or understandable responses By adjusting these parameters, users can tailor the language model’s output

to their specific needs

Applications in Information Retrieval

ChatGPT can also be used to search for information by asking it questions

in natural language To do this, it is possible to use a chatbot interface with a pre-trained model The model is trained from a large amount of text data, so it can answer a variety of questions based on its knowledge of language and experience Users can ask questions using clear and precise sentences to obtain more accurate answers It is also possible to adjust the temperature level of sampling to control the creativity of responses and add a level of noise to generate more diverse responses

Here is an example of information search with ChatGPT:

User: What is climate change, and how does it affect

our planet?

Trang 33

ChatGPT: Climate change is a global phenomenon that occurs

due to the increase of greenhouse gases in the Earth's atmosphere, mainly caused by human activities such as burning fossil fuels This leads to an increase in the planet's average temperature, which can have devastating effects such as melting of ice, sea- level rise, extreme weather events, and loss of biodiversity Governments, businesses, and individuals can take measures to reduce their carbon footprint and mitigate the effects of

Based on ChatGPT’s responses, it is obviously possible to continue the discussion started with it For example:

User: What measures can be taken to mitigate the effects

of climate change?

ChatGPT: There are many measures that can be taken to

mitigate the effects of climate change, including:

• Reducing greenhouse gas emissions by using renewable energy sources such as solar and wind power, and limiting energy consumption

• Improving energy efficiency by using more efficient technologies and encouraging energy-saving

behaviors

• Encouraging the use of public transport, electric vehicles, and low-carbon transport modes

Trang 34

• Promoting sustainable agriculture and forestry practices to help store carbon and reduce greenhouse gas emissions.

• Investing in research and development of cleaner and more efficient technologies

• Raising public awareness about the issues of

climate change and encouraging adoption of more environmentally friendly behaviors

• Encouraging international cooperation to combat climate change and achieve global emissions

reduction targets

CHAPTER 4

ChatGPT Training

This chapter explains the training of ChatGPT, focusing on the technical aspects of training this language model and the different strategies to optimize its performance In this chapter, we will explore the important parameters for training ChatGPT, the available training tools, and

techniques to improve the model’s performance

Pre-training and Training of ChatGPT

Pre-training and training are two distinct steps in developing language models like ChatGPT. Pre-training involves training the model on a large amount of unlabeled data, while training involves fine-tuning the model

on a specific task with labeled data

Labeled data is training data that has been previously annotated or marked with labels indicating the expected response or class for each data example For example, in an image classification problem, each image may

be labeled with the class it belongs to (cat, dog, bird, etc.)

Thus, during ChatGPT’s pre-training, the model is trained on a large amount of raw text from a variety of sources, such as news articles, books, and websites This step allows ChatGPT to understand the structure of language and learn to predict the next words in a given sequence

Trang 37

Next, during training, the model is fine-tuned on a specific task using labeled data For example, if we want to train ChatGPT to answer questions,

we could train it on a dataset of questions and answers, where the questions are provided as input and the expected answers are given as output

By fine-tuning the model on a specific task, ChatGPT can improve its performance for that particular task by using the knowledge gained during pre-training on a large amount of data

Fine-Tuning

Fine-tuning is a technique used to adapt a pre-trained machine learning model to a specific task by re-training it on a smaller dataset specific to that task

Let’s take the example of using ChatGPT for poem generation

ChatGPT is a pre-trained machine learning model on a large amount of textual data However, to generate poems, we need to retrain the model on

a dataset specific to poetry

To do this, we select a dataset of poems, which we use to retrain

ChatGPT using the fine-tuning technique We adjust the weights of the model’s words using the specific poetry data, while preserving the prior knowledge learned by the model during its initial pre-training

Thus, by using fine-tuning, we can adapt ChatGPT to poem generation while leveraging the prior knowledge it acquired during its initial pre- training on a large amount of textual data

Data Collection and Preparation

The collection and preparation of data in ChatGPT refers to the process of gathering and preparing a large corpus of text to be used as training data for the model This often involves collecting texts from various sources such as books, articles, web pages, and social media, as well as cleaning

Trang 38

and formatting them to be used as inputs for the model The quality of the collected and prepared data can have a significant impact on the quality of the model’s performance.

Here is an example of collecting and preparing data for the topic of

“sushi making”:

1 Data collection: First, raw data can be collected

from sources such as cookbooks, recipe websites,

culinary blogs, YouTube videos, etc The collected

data may include ingredients, step-by-step

instructions, cooking times, necessary tools and

equipment, etc

2 Data cleaning: Next, the raw data may require

cleaning to remove duplicates, errors, and

inconsistencies For example, quantity measures

can be standardized using the same system of

measurement, ingredients can be normalized for

spelling and naming, and steps can be ordered

consistently

3 Data encoding: The cleaned data can then be

encoded in numerical form to enable processing

by the ChatGPT model For example, words and

phrases can be encoded as real-number vectors

using techniques such as Word2Vec or GloVe

(Global Vectors for Word Representation)

4 Data splitting: Finally, the encoded data can be split

into training, validation, and test sets to train, tune,

and evaluate the ChatGPT model

Trang 39

These steps of data collection and preparation can ensure that the ChatGPT model is trained on high-quality and relevant data for the

specific topic of sushi making, which can improve the quality of the

generated text results

ChatGPT Training Settings

Using parameters for training ChatGPT allows for customization of the model based on the specific needs of the application Parameters can adjust variables such as model size, layer depth, learning rate, and more By adjusting these parameters, it is possible to optimize the performance of the model for specific tasks such as automatic translation or content creation.The “model size” parameter is an important factor when training ChatGPT because it determines the complexity of the language model that will be used for the given task A larger model size is capable of learning more complex and precise language representations, which often results in better performance in tasks such as text generation, automatic translation,

or content creation However, increasing the model size can result in higher computation costs and require more training data to achieve good performance Therefore, it is essential to find a balance between model complexity and available resources

The “layer depth” parameter refers to the number of layers in the ChatGPT neural network A higher value for this parameter means

that the network will have more layers and, therefore, more capacity to capture complex word relationships This can optimize the performance

of ChatGPT by helping the model learn richer and more abstract word representations, which can improve its ability to understand the meaning

of input text and generate more coherent and relevant responses However, increasing the layer depth can also increase training time and model complexity, so it is important to find the right balance based on the

application’s needs

Trang 40

The “learning rate” parameter is used to control the amount of weight update the model receives at each training iteration If the learning rate is too low, the model will learn slowly and may not converge to an optimal solution If the learning rate is too high, the model may skip local optima and fail to converge to the global optimal solution Thus, choosing the right value for the learning rate can help optimize the model’s performance by ensuring quick and stable convergence to an optimal solution.

Finding the right value for the learning rate parameter can be an iterative process that involves multiple trial and error attempts Generally,

it is recommended to start with a base value and adjust from there based

on training performance If the model does not appear to converge or converges too slowly, the learning rate can be increased If the model appears unstable or performance decreases, the learning rate can be reduced

Ultimately, the training parameters must be chosen wisely to optimize learning and prevent overfitting This requires experience and expertise in natural language processing and machine learning

Training Tools Available

There are several ChatGPT training tools available; here are a few:

• Hugging Face Transformers: This is an open-source

deep learning framework that allows for training and

using language models, including ChatGPT, with a

simple and easy-to-use API

• TensorFlow: This is a popular deep learning framework

with a large community of developers and researchers,

which also allows for training language models,

including ChatGPT
