MesaNet uses optimal test-time training for better sequence modeling

By PulseAugur Editorial · [1 sources] ·

Researchers have developed MesaNet, a novel sequence modeling architecture that optimizes performance through locally optimal test-time training. This approach, derived from an in-context loss minimized by a conjugate gradient solver, allows for chunkwise parallelization and scalability. Experiments show MesaNet achieves lower perplexity and better downstream performance than previous recurrent neural networks, particularly on tasks requiring long context, though it does increase inference computation.

    MesaNet: Sequence Modeling by Locally Optimal Test-Time Training

    arXiv:2506.05233v2 Announce Type: replace-cross Abstract: Sequence modeling is currently dominated by causal transformer architectures that use softmax self-attention. Although widely adopted, transformers require scaling memory and compute linearly during inference. A recent str…
