arXiv:2607.07386v1 Announce Type: new Abstract: Linear attention models allow a fixed state size and a fixed amount of compute per token. However, due to their limited state size, linear attention models fall behind in long-context recall compared to softmax-attention-based transformer architectures. Increasing the state size of linear attention improves recall performance but at the cost of higher FLOPs. In this work, we introduce Sparse Delta Memory (SDM), an architecture that scales the hidden state of gated linear RNNs to orders of magnitude higher capacity using a sparse addressing scheme
The rapid advancement in AI necessitates continuous innovation in model architectures to overcome existing scaling limitations, particularly for long-context understanding.
Improving the efficiency of long-context recall in AI models could significantly enhance capabilities for advanced AI applications, making them practical for more complex tasks.
This research outlines a method to significantly scale the state size of linear RNNs, potentially allowing them to process much longer sequences of information with greater efficiency than current transformer-based models.
