Phasor Transformer offers efficient alternative to attention for time-series modeling

By PulseAugur Editorial · [1 sources] ·

Researchers have introduced the Phasor Transformer, a novel block designed to address the quadratic bottleneck in attention mechanisms for time-series data. This new approach represents sequence states on the unit-circle manifold and utilizes a combination of trainable phase-shifts and a parameter-free Discrete Fourier Transform for global token coupling. The resulting Large Phasor Model (LPM) demonstrates competitive performance against self-attention models at a fraction of the parameter count, establishing a new efficiency-accuracy frontier for temporal modeling in oscillatory domains.

IMPACT Offers a more efficient approach to time-series modeling, potentially impacting applications requiring long-context understanding.

    The Phasor Transformer: Resolving Attention Bottlenecks on the Unit Circle

    arXiv:2603.17433v2 Announce Type: replace-cross Abstract: Transformer models have redefined sequence learning, yet dot-product self-attention introduces a quadratic token-mixing bottleneck for long-context time-series. We introduce the Phasor Transformer block, a phase-native alt…
