There are two fundamental innovations: the idea of token vectors and +self-attention. + +Rather than encoding words (or perhaps, amino acids) as themselves in a machine +learning model, they are encoded as token vectors. Tokens can be full words, +but are usually fragments of words. In the case of amino acids, each amino acid +would be a "token". For example: + + Token -> Amino Acid + 1 -> A + 2 -> C + 3 -> D + ... + 20 -> Y + 21 -> * + +These tokens are usually just integers, corresponding with a map to the actual +words they represent. These tokens are then mapped to a vector embedding: + + 1 -> [0.0, 0.2, 0.1, ... ] (length:512) + 2 -> [0.9, 0.0, 0.2, ... ] (length:512) + 3 -> [0.2, 0.4, 0.6, ... ] (length:512) + +In the original instantiation of vector embeddings, one could think of them as +representing an idea in high-dimensional space. For example, the concept of +gender could be the difference between the vector between "mom" and "dad" +(which correspondingly would also be the difference between the vector between +"aunt" and "uncle"). + +The idea is that these vector embeddings can be compared to each other to find +the most relevant portions of a sequence for a model, otherwise known as +"attention". When the model is comparing to itself, this is called +"self-attention". A good example of self attention is looking at the words in a +sentence to find out the meaning, or the way each amino acid in a protein +interacts with each other amino acid. + +Transformers are a specific deep learning model architecture that depends on +self-attention plus feed-forward neural networks, layed on top of each other. +Because of the multiple layers of self-attention, transformers are very good +at figuring out the context of information, and how it relates to other +information in a sequence. These have found their way into biotechnology +research. + +Alphafold is a great example of transformer-architecture applied to biological +data: by utilizing the self-attention mechanisms of transformers, it is able +to more effectively predict protein structure than any other piece of software. + +This package's intention is to make a tokenizer for amino acid data, such that +sources like uniprot can be used to train LLMs. Essentially, we want to convert +amino acid sequence data to a list of int32 integers in an easy-to-use way. + +We will be using Karpathy's datafile format from llm.c, written here: + + https://github.com/karpathy/llm.c/blob/master/dev/data/data_common.py + +In brief, there is a header with 256 int32, followed by tokens as uint16.
