Memory-efficient Transformers via Top-k Attention

This repository contains the accompanying code for the paper:

"Memory-efficient Transformers via Top-k Attention." Ankit Gupta, Guy Dar, Shaya Goodman, David Ciprut, Jonathan Berant. In SustaiNLP, 2021. [PDF]

Structure

The repository contains:

• our implementation/benchmarking of top-k attention (in nocache_attention dir)
• unifiedqa/T5 finetuning/inference using our top-k attention at feed-forward layers (in unifiedqa dir)

Coming Soon:

• BERT QA model with top-k attention
• T5 multi-head layers with top-k attention (current code is only for FF layers)
