About this paper
Joshua Nunley
The Frustrated Synchronization Network (FSN) introduces an oscillator-based attention mechanism that models attention as a learned, interpretable frustrated coupling law. It achieves lower validation loss than Transformer baselines on character-level text and code, particularly improving long-range copying by synchronizing token representations towards data-determined offsets rather than simple consensus.
Key insights
- Integrating 'frustrated synchronization' allows attention mechanisms to perform 'anticipation' or 'continuation' by synchronizing to data-dependent transitions, moving beyond simple consensus.
- Attention can be expressed as a learned, mathematically interpretable coupling law, where kernel coefficients directly correspond to established concepts in synchronization theory, offering transparency into its mechanics.
- The 'successor-field' term in the coupling kernel, which couples a token to the successor phase of attended tokens, is crucial for the FSN's enhanced long-range copying capabilities, facilitating 'retrieval-to-continuation'.
