# mlsae-pythia-70m-deduped-x64-k256-tfm

A Multi-Layer Sparse Autoencoder (MLSAE) trained on the residual stream
activation vectors from every layer of
[EleutherAI/pythia-70m-deduped](https://huggingface.co/EleutherAI/pythia-70m-deduped)
with an expansion factor of 64 and k = 256, over 1 billion tokens from
[monology/pile-uncopyrighted](https://huggingface.co/datasets/monology/pile-uncopyrighted).
This model includes the underlying transformer.
