Regional risk classification in emerging automobile insurance markets using Bayesian Hurdle models
Abstract Accurate risk classification in automobile insurance claim frequency in emerging markets remains a critical challenge for actuarial practice and …
Article scientifique
Explaining and Preventing Alignment Collapse in Iterative RLHF
Reinforcement learning from human feedback (RLHF) typically assumes a static or non-strategic reward model (RM). In iterative deployment, however, the …
