Building a Large Language Model from Scratch

To truly understand the foundations of Chachi PT and similar language models, it's important to start with the basics. In this section, we'll explore how a large language model is built from scratch, assuming little prior knowledge in terms of the technology involved. These large language models serve as the backbone of Chachi PT and are vital for its functionality. We'll cover the essential steps and processes involved in creating these models, providing You with a comprehensive understanding of their construction.

Tokenization and Representing Natural Language

The representation of natural language in machines is a crucial and complex challenge in the field of natural language processing (NLP). In this section, we'll explore the process of tokenization, which involves mapping individual words to numerical values. We'll discuss the pitfalls of representing words individually and introduce the concept of subword tokenization. By examining practical examples and techniques, we'll demonstrate how tokenization allows us to represent text as a sequence of tokens, unlocking the ability to perform higher-level operations on the text.

Word Embeddings: Creating Semantically Similar Word Vectors

Word embeddings play a vital role in NLP models by enabling the learning of semantically similar word representations. In this section, we'll dive deeper into the world of word embeddings and the significance of these vectors in language models. Through the use of large, high-dimensional vectors, we can map words to positions in vector space, where similar words are located nearby. We'll explore the power and flexibility of word embeddings, as well as their practical application in language modeling.

The Transformer Architecture: Powering Language Models

The Transformer architecture lies at the heart of modern language models and has revolutionized the field of NLP. In this section, we'll take a closer look at the Transformer's design and its role in powering language models like Chachi PT. We'll explore the self-Attention mechanism and the feed-forward block components that make up the Transformer. By understanding the inner workings of this architecture, we can appreciate its effectiveness in optimizing language models for efficiency and accuracy.

Training Language Models with Gradient Descent

Training a language model involves optimizing its parameters to find the best possible approximation of the probability of the next token given the previous tokens. In this section, we'll delve into the training process of language models using gradient descent. We'll explore how gradient descent enables us to compute gradients for each parameter and update them in a way that maximizes the likelihood of the actual data. Through iterative optimization, we can train models to accurately predict what comes next in a sequence of tokens.

Scale: The Key to High-Quality Models

The performance and quality of a language model heavily depend on the scale of the data it is trained on. In this section, we'll emphasize the importance of scale in achieving high-quality models. We'll discuss the use of vast datasets collected from various sources, including the internet, to train language models effectively. The scale of data allows models like Chachi PT to learn from a vast amount of information and generate diverse and accurate predictions.

Conditional Generation: Bootstrapping Predictions

Conditional generation is a crucial aspect of language models, enabling the generation of coherent and contextually appropriate sequences of text. In this section, we'll delve into conditional generation and the process of bootstrapping predictions. By plugging in a prefix and iteratively generating predictions Based on the model's learned function, we can Create long sequences of text. We'll explore the complexities and techniques involved in generating text that aligns with given conditions.

Scaling up in Size and Parameters

As language models Continue to evolve, researchers are constantly pushing the boundaries of scale. In this section, we'll explore the concept of scaling up models in both size and parameters. We'll discuss the growth in model size, from models with billions of parameters to models with hundreds of billions of parameters. We'll examine the impact of increased scale on model capabilities, performance, and the ability to capture long-range dependencies in text.

Using pretrained models with Hugging Face
