Researchers introduce MC-RFM, a novel framework for efficiently adapting frozen vision models to new tasks using mixed-curvature Riemannian geometry. The method represents adapted features on a product manifold combining hyperbolic and Euclidean spaces, outperforming existing parameter-efficient adaptation techniques across multiple benchmarks and backbone architectures.
Researchers introduce EvoTest, an evolutionary framework enabling AI agents to improve performance across consecutive test episodes without fine-tuning or gradients. The method outperforms existing adaptation techniques on a new Jericho Test-Time Learning benchmark, successfully winning games that all baseline methods failed to complete.
Research reveals that large language models like DeepSeek-V3.2, Gemini-3, and GPT-5.2 show rigid adaptation patterns when learning from changing environments, particularly struggling with loss-based learning compared to humans. The study found LLMs demonstrate asymmetric responses to positive versus negative feedback, with some models showing extreme perseveration after environmental changes.
Researchers challenge three foundational assumptions in reinforcement learning—treating environments as Markov processes, learning as policy optimization, and agents as scalar reward maximizers—proposing instead a framework grounded in evolutionary dynamics and thermodynamic theories of agency. The work suggests reconceptualizing agent learning as adaptation rather than optimization, with goals extending beyond simple reward signals.
Researchers introduce Foundation Preserving LoRA (FoLoRA), a new optimization framework that addresses a critical challenge in fine-tuning foundation models: maintaining pre-trained capabilities while adapting to specialized downstream tasks. Using a generalized Rayleigh-quotient approach, FoLoRA intelligently balances task performance gains against knowledge forgetting during training.
Researchers introduce FreqAdapter, a parameter-efficient fine-tuning method that operates in the frequency domain rather than signal space to adapt pre-trained models like CLIP and LLaVA. The approach uses multi-scale adaptation strategies and text-guided prompts to improve model efficiency and performance with minimal training parameters and fast convergence.
Researchers identify a critical flaw in robotic manipulation training: collecting diverse single-shot demonstrations paradoxically degrades performance due to estimation noise. Their proposed Anchor-Centric Adaptation (ACA) framework prioritizes repeated demonstrations at core tasks before expanding coverage, significantly improving robot reliability under strict data budgets.
Researchers introduce TeLAPA, a continual reinforcement learning framework that maintains diverse policy archives instead of relying on single-model preservation, addressing the loss of plasticity problem where retained policies fail to serve as effective starting points for rapid adaptation across new tasks.
Researchers demonstrate that meta-learning agents in simulated robot wrestling can quickly learn to defeat stronger non-meta-learning opponents. The study also shows these agents can adapt to physical malfunctions, highlighting the potential for AI systems to rapidly adjust strategies and overcome challenges.
