HARMONIC LOSS TRAINS INTERPRETABLE AI MODELS

Harmonic loss is an alternative to cross-entropy loss for training neural networks that offers better interpretability and faster convergence through scale invariance and finite convergence points. Experiments across algorithmic, vision, and language datasets, demonstrate that models trained with harmonic loss show superior performance in interpretability, data efficiency, and reduced grokking compared to standard models. Harmonic loss could be particularly valuable for applications with limited data or where interpretability is crucial.

CONVEX OPTIMIZATION THEORY AND LEARNING-RATE SCHEDULING FOR LARGE MODEL TRAINING

Learning-rate schedules for large models closely match theoretical bounds from non-smooth convex optimization. These authors provide a bound for constant schedules with linear cooldown, showing cooldown's practical benefits through the absence of logarithmic terms in the bound. Their findings enabled practical improvements in training Llama-type models through optimal learning-rate extension and cross-schedule transfer.
