Researchers demonstrate that transformer models equipped with continuous latent context tokens can efficiently implement online learning algorithms without parameter updates. A small GPT-2-style model trained with this approach outperforms much larger language models on synthetic online prediction tasks, suggesting a promising architectural direction for adaptive AI systems.
Researchers introduce Q2RL, a novel algorithm that combines behavior cloning with reinforcement learning to enable robots to improve their policies through online interaction.

The method demonstrates superior controllability and generalization across reinforcement learning benchmarks, potentially advancing AI decision-making systems.
Researchers introduce MemQ, a novel framework that applies Q-learning eligibility traces to episodic memory in large language model agents, enabling credit assignment across memory dependencies recorded in provenance DAGs. The approach achieves superior performance across six diverse benchmarks, with gains up to 5.7 percentage points on multi-step tasks requiring deep memory chains.
Researchers propose SafeQIL, a new Q-learning algorithm that learns safe policies from expert demonstrations in constrained environments where safety constraints are unknown. The approach balances maximizing task rewards while maintaining safety by learning from demonstrated trajectories that successfully complete tasks without violating hidden constraints.
Researchers propose QSIM, a new framework that addresses systematic Q-value overestimation in multi-agent reinforcement learning by using action similarity weighted Q-learning instead of traditional greedy approaches.

Researchers propose Enhanced-FQL(λ), a fuzzy reinforcement learning framework that combines fuzzified eligibility traces and segmented experience replay to improve interpretability and efficiency in continuous control tasks. The method demonstrates competitive performance with neural network approaches while maintaining computational simplicity through interpretable fuzzy rule bases rather than complex black-box architectures.
Researchers introduce Chunk-Guided Q-Learning (CGQ), a new offline reinforcement learning algorithm that combines single-step and multi-step temporal difference learning approaches. The method achieves better performance on long-horizon tasks by reducing error accumulation while maintaining fine-grained value propagation, with theoretical guarantees and empirical validation on OGBench tasks.
Researchers developed a new pessimistic auxiliary policy for offline reinforcement learning that reduces error accumulation by sampling more reliable actions. The approach maximizes the lower confidence bound of Q-functions to avoid high-value actions with potentially high errors during training.
Researchers introduce iterated Shared Q-Learning (iS-QL), a new reinforcement learning method that bridges target-free and target-based approaches by using only the last linear layer as a target network while sharing other parameters. The technique achieves comparable performance to traditional target-based methods while maintaining the memory efficiency of target-free approaches.
