📖 Full Retelling
Researchers introduced 'HyperMLP,' a novel perspective on sequence modeling in machine learning through research paper arXiv:2602.12601v1 published on February 18, 2026, challenging conventional views of self-attention mechanisms by proposing that autoregressive attention heads can be understood as dynamic two-layer MLPs whose weights are instantiated from context history. The paper presents a fundamental rethinking of how attention operates in transformer models, moving away from the traditional probabilistic query-key lookup interpretation that has dominated the field. This new perspective views attention scores as forming an ever-growing hidden representation rather than maintaining normalized values, potentially simplifying the theoretical understanding while maintaining expressive power. The researchers argue that this unified approach could lead to more efficient architectures and better intuition about how sequence information is processed in modern deep learning models.

Algorithm for modelling sequential data
In deep learning, the transformer is an artificial neural network architecture based on the multi-head attention mechanism, in which text is converted to numerical representations called tokens, and each token is converted into a vector via lookup from a word embedding table. At each layer, each tok...

Abstract: Self-attention is often viewed as probabilistic query-key lookup, motivating designs that preserve normalized attention scores and fixed positional semantics. We advocate a simpler and more unified perspective: an autoregressive attention head can be viewed as a dynamic two-layer MLP whose weights are instantiated from the context history. From this view, attention scores form an ever-growing hidden representation, and standard MLP activations s
