Boosting Reinforcement Learning in 3D Visuospatial Tasks Through Human-Informed Curriculum Design

A new algorithm, Deep Gaussian Process Proximal Policy Optimization (GPPO), has been introduced to enhance uncertainty estimation in Reinforcement Learning (RL), particularly in control tasks requiring a balance between safe exploration and efficient learning. GPPO utilizes Deep Gaussian Processes to approximate both policy and value functions, maintaining competitive performance with existing methods while offering calibrated uncertainty estimates.

A recent study has framed the self-healing process of material systems as a Reinforcement Learning (RL) problem within a Markov Decision Process (MDP), demonstrating that RL agents can autonomously derive optimal policies for maintaining structural integrity while managing resource consumption. The research highlighted the superior performance of continuous-action agents, particularly the TD3 agent, in achieving near-complete material recovery compared to traditional heuristic methods.

The introduction of Perceptual-Evidence Anchored Reinforced Learning (PEARL) marks a significant advancement in multimodal reasoning, addressing the limitations of traditional Reinforcement Learning with Verifiable Rewards (RLVR) in Vision-Language Models (VLMs). PEARL enhances reasoning by anchoring it to verified visual evidence, thus mitigating issues like visual hallucinations and reward hacking.

A new study has introduced a framework for deterministic inference across varying tensor parallel sizes, addressing the issue of training-inference mismatch in large language models (LLMs). This mismatch arises from non-deterministic behaviors in existing LLM serving frameworks, particularly in reinforcement learning settings where different configurations can yield inconsistent outputs.

A new paper presents a hybrid framework for portfolio optimization that combines Long Short-Term Memory (LSTM) forecasting with Proximal Policy Optimization (PPO) reinforcement learning. This innovative approach aims to enhance portfolio management by leveraging deep learning to predict market trends and dynamically adjust asset allocations across various financial instruments, including U.S. and Indonesian equities, U.S. Treasuries, and cryptocurrencies.

Recent research has critically evaluated the effectiveness of Reinforcement Learning with Verifiable Rewards (RLVR) in enhancing the reasoning capabilities of large language models (LLMs). The study found that while RLVR-trained models perform better than their base counterparts on certain tasks, they do not exhibit fundamentally new reasoning patterns, particularly at larger evaluation metrics like pass@k.

PrismAudio has introduced a novel framework for Video-to-Audio (V2A) generation that utilizes Reinforcement Learning and specialized Chain-of-Thought (CoT) modules to address the challenges of semantic consistency, audio-visual synchrony, aesthetic quality, and spatial accuracy. This approach decomposes traditional reasoning into four distinct modules, each with targeted reward functions, enhancing the model's interpretability and performance.

A new reinforcement learning platform named ContagionRL has been introduced, designed for reward engineering in spatial epidemic simulations. This platform allows researchers to evaluate how different reward function designs influence survival strategies in various epidemic scenarios, integrating a spatial SIRS+D epidemiological model with adjustable environmental parameters.
