a position paper argues that in high-dimensional settings, many different mechanisms can produce the same data, so predictive success does not prove a model has found the true mechanism, and large language models can hide this by giving a single fluent explanation.
aura-mem uses a learned gate to write only when observations change actions, keeping memory fixed at 4,224 bytes regardless of episode length.
periodic and soft target updates can guarantee convergence in linear q-learning under explicit spectral and step-size conditions.
a new method uses gradient tests instead of validation loss to decide when to stop training gradient boosted trees, avoiding the need for a patience parameter.
a new diagnostic reveals that common anomaly detection benchmarks become unreliable when held-out classes overlap with normal data in representation space.
a new framework aligns structured electronic health record representations with large language models to improve clinical prediction and reasoning.
