The Adaptive Policy Gradient paper (arXiv:2305.15193) was first posted on 24 May 2023 and withdrawn on 24 September 2025 citing unresolved technical issues. Read more: https://getnews.me/adaptive-policy-gradient-method-withdrawn-after-technical-issues/ #reinforcementlearning #policygradient #arxiv

An algorithm for multi‑objective RL maximizes a concave utility and reaches an ε‑neighborhood after O(M⁴σ²/(1‑γ)⁸ε⁴) trajectories (arXiv:2105.14125). Read more: https://getnews.me/policy-gradient-method-advances-multi-objective-reinforcement-learning/ #multigoalrl #policygradient

A new policy‑gradient method integrates Bayesian risk handling into reinforcement learning, offering provable convergence at rate O(T⁻½ + r⁻½) and extending to episodic MDPs.
