A user on r/MachineLearning is seeking solutions for long-range recall issues in linear attention models, particularly for DNA sequence modeling which can reach millions of tokens. Standard softmax attention is computationally prohibitive for such long sequences. The user found that their linear attention model, and even HyenaDNA, performed poorly on a needle-in-a-haystack benchmark with recall rates around 25%, suggesting a fundamental limitation rather than an implementation error. Smaller context windows showed better recall, but performance degraded significantly with longer sequences. AI
