Rethinking Expressivity and Efficiency in Test-Time Training

E²-TTT derives a closed-form chunk-level state transition that exactly reproduces per-token update dynamics, enabling parallel training that retains temporal structure, matches chunk-wise throughput, and achieves over 90% needle-in-a-haystack accuracy at 8× training length.

Bayesian Optimization with Fisher Information Geometry: Gradient Bounds and Trust-Region Methods

Pulling back the Fisher metric yields a local sensitivity tensor that bounds acquisition gradients and explains high-dimensional BO failures, leading to the FITR trust-region method that replaces lengthscale heuristics with local Fisher weights.
