Transformer Tricks

A collection of tricks to simplify and speed up transformer models:

• Slim attention: [paper], [video], [podcast], [notebook], [code-readme], [reddit]
• Matrix-shrink [work in progress]: [paper]
• Flash normalization: [paper], [podcast], [notebook], [code-readme]
• Precomputing the first layer: [paper], [podcast]
• Removing weights from skipless transformers: [paper], [podcast], [notebook]

Many of these tricks follow a recent trend of removing parts from neural networks such as RMSNorm’s removal of mean centering from LayerNorm, PaLM's removal of bias-parameters, decoder-only transformer's removal of the encoder stack, and of course transformer’s revolutionary removal of recurrent layers.

For example, our FlashNorm removes the weights from RMSNorm and merges them with the next linear layer. And slim attention removes the entire V-cache from the context memory for MHA transformers.
