Efficient Heteroscedastic Bayesian Optimization for Risk-Aware AutoRL
arXiv:2607. 26680v1 Announce Type: new Abstract: Reinforcement learning (RL) has shown remarkable success across a wide range of complex tasks.
The paper proposes treating the chain ladder’s pattern selection as a supervised‑learning problem, framing adjustments as penalties and hyperparameters on a convex loss function. It introduces generalized data weights with decay and power parameters, benchmark shaping, and Whittaker‑Henderson smoothing, all combined into a single linear system for minimisation. The authors demonstrate the approach with a real Schedule P triangle, showing how experience‑based and prospective adjustments can be objectively set via a training loop and reserve validation.

The paper introduces Difficulty-Calibrated Flow Matching, a method that adapts the noise-to-data interpolation schedule in Conditional Flow Matching based on a pilot run’s loss profile. By setting the schedule to the quantile function of this difficulty profile, the training trajectory spends more time where the velocity is hardest to learn. Experiments on CIFAR-10, MNIST, and Fashion‑MNIST show that this calibrated path achieves the best FID on CIFAR‑10 and outperforms all fixed schedules in large‑batch, few‑update settings, where compute is most limited.
