Since Transformers process words in parallel rather than sequences, positional encodings are added to give the model a sense of word order.

You cannot feed raw text into a model. You must use a tokenizer (like Byte-Pair Encoding or WordPiece) to break text into numerical "tokens." build a large language model from scratch pdf

A faster and more memory-efficient way to compute attention. Since Transformers process words in parallel rather than

Techniques like Data Parallelism (splitting data across GPUs) and Model Parallelism (splitting the model layers across GPUs) are essential to avoid memory bottlenecks. 4. The Training Process Training involves two main phases: build a large language model from scratch pdf

Reduces memory usage and speeds up training without significantly sacrificing accuracy.
