# Model Card for tim-lawson/mlsae-pythia-70m-deduped-x4-k32
A Multi-Layer Sparse Autoencoder (MLSAE) trained on the residual stream activation
vectors from [EleutherAI/pythia-70m-deduped](https://huggingface.co/EleutherAI/pythia-70m-deduped) with an
expansion factor of R = 4 and sparsity k = 32, over 1 billion
tokens from [monology/pile-uncopyrighted](https://huggingface.co/datasets/monology/pile-uncopyrighted).
This model is a PyTorch TopKSAE module, which does not include the underlying
transformer.
