    WriteSAE: Sparse Autoencoders for Recurrent State

    Researchers have developed WriteSAE, a novel sparse autoencoder designed to manipulate the matrix updates within recurrent language model states. This method learns rank-1 matrix atoms that directly replace the model's own matrix updates, showing a significant improvement in final token distribution accuracy. The technique has been successfully applied to models like Gated DeltaNet and Mamba-2, demonstrating its potential for steering model generation and understanding internal state dynamics. AI

    IMPACT Enables direct intervention and steering of recurrent language model states, potentially leading to more controllable and understandable AI generation.

    Gated DeltaNet-2: Decoupling Erase and Write in Linear Attention

    NVIDIA has introduced Gated DeltaNet-2, a new linear attention layer designed to improve memory editing in recurrent neural networks. This model separates the processes of erasing old information and writing new information using distinct channel-wise gates, addressing a limitation in previous delta-rule architectures. Trained on 100 billion tokens with 1.3 billion parameters, Gated DeltaNet-2 demonstrates superior performance over existing models like Mamba-2 and KDA, particularly in long-context retrieval tasks.
