Study Notes

Transformer Architecture

The transformer architecture has an encoder and a decoder, each consisting of 6 identical layers.
Each layer has two sub-layers: multi-head self-attention and a feed-forward neural network.
The encoder takes in input embeddings and produces output embeddings.
The decoder takes in output embeddings and produces probabilities.

Transformer Encoder

The encoder has self-attention as its core building block.
Self-attention allows each word in the input sequence to interact with every other word.

Impact of Transformers

Transformers have revolutionized the field of NLP and ML, enabling significant progress in various tasks.
The transformer architecture has led to the development of powerful models that can match or exceed human-level performance.

History of NLP Models

Before transformers, recurrent models such as LSTMs were widely used in NLP tasks.
Recurrent models were used for sequence-to-sequence problems and encoder-decoder models.
The transformer architecture has replaced recurrent models as the de facto strategy in NLP.

Scaling Laws

The performance of transformers improves smoothly as model size, training data, and compute resources increase.
This power-law relationship has been observed over multiple orders of magnitude with no sign of slowing.

Drawbacks and Variants

There are drawbacks and variants of transformers that will be discussed further.
