MindfulAgents is a large language model-driven multi-agent system that personalizes mindfulness meditation through expert-aligned script generation and real-time adaptation, significantly improving user engagement, self-awareness, and stress reduction in both short-term and long-term studies.
This study demonstrates that DNA foundation models (DNABERT-2, Evo 2, and NTv2) are vulnerable to model inversion attacks, where adversaries can reconstruct sensitive genomic sequences from shared embeddings with high accuracy, particularly for shorter sequences and per-token representations, thereby highlighting critical privacy risks in Embeddings-as-a-Service frameworks.
This paper establishes that while policy gradient methods can achieve near-optimal performance in post-training autoregressive models when staying within the base model's support, they face an exponential query barrier to generalize beyond it unless process rewards are utilized to leverage token-level likelihood quantiles.
This paper presents a principled analysis of why imitation learning is effective for quadruped locomotion with limited data and proposes a new offline method that enables robots to learn robust walking policies from just a few seconds of demonstration.
This paper introduces Elenchus, a dialogue system that leverages prover-skeptic interactions between a human expert and an LLM to construct knowledge bases grounded in inferentialist semantics, mapping dialectical states to formal logic to explicitly capture and verify the inferential relationships and design rationales of complex ontologies like PROV-O.
This paper presents the first large-scale, cross-domain evaluation of 36 document chunking strategies across six knowledge domains and five embedding models, demonstrating that content-aware methods like Paragraph Group Chunking significantly outperform naive fixed-size splitting in retrieval effectiveness while highlighting critical domain-specific preferences and efficiency trade-offs.
This paper introduces NePPO, a novel multi-agent reinforcement learning pipeline that computes approximate Nash equilibria in general-sum games by learning a player-independent potential function to transform the mixed cooperative-competitive environment into an approximating cooperative game.
The paper introduces Diffusion Controller (DiffCon), a unified control-theoretic framework that models reverse diffusion sampling as a state-only stochastic control problem within LS-MDPs, enabling the derivation of practical fine-tuning algorithms and a lightweight side-network architecture that outperforms existing gray-box and white-box adaptation methods.
This paper demonstrates that optimizing for objectives like profit or crime reduction while maintaining a zero Average Treatment Effect (ATE) can mask significant unfairness driven by confounding, thereby arguing that fairness regulations must shift from evaluating aggregate decision-level outcomes to scrutinizing model-level causal mechanisms.
This paper introduces a lightweight, probabilistic world model built on a pretrained vision foundation model that generates uncertainty-based runtime monitors to accurately detect anomalous failures in bimanual manipulators, outperforming existing baselines while requiring significantly fewer trainable parameters.
This study analyzes how 80 student design teams integrated generative AI into their creative process, revealing that while AI serves as a cognitive accelerator for early-stage tasks like brainstorming, human competencies in agency, domain knowledge, imagination, and taste remain essential for interpreting context, validating outputs, and refining design solutions.
This paper introduces Self-MOA, a fully automated framework that aligns small language models using weak supervision from automated evaluators to achieve significant safety improvements with minimal training data while preserving helpfulness.
The paper introduces \textsc{ReSched}, a minimalist deep reinforcement learning framework that simplifies the Flexible Job Shop Scheduling Problem by condensing the state space to four essential features and utilizing a modified Transformer architecture, achieving superior performance and generalization across various scheduling variants compared to existing methods.
Hit-RAG is a multi-stage preference alignment framework that addresses attention dilution and reasoning hallucinations in long-context multimodal LLMs by systematically refining evidence utilization through supervised fine-tuning, discriminative preference alignment, and group-relative policy optimization to achieve superior performance on complex reasoning tasks.
This paper proposes the Hierarchical Memory Tree (HMT), a structured framework that decouples high-level task logic from site-specific action details through a three-level abstraction hierarchy, thereby significantly enhancing the generalization and robustness of large language model-based web agents in unseen environments.
The paper introduces DeepEarth, a self-supervised multi-modal world model featuring Earth4D, a novel 4D space-time positional encoder that achieves state-of-the-art ecological forecasting performance and outperforms larger foundation models through efficient planetary-scale learning.
This paper proposes CAPL, a framework that mitigates multi-image hallucinations in large vision-language models by introducing a selectable image token interaction mechanism for fine-grained cross-image alignment and a preference learning strategy that trains the model to rely on genuine visual evidence rather than textual priors.
This paper presents a user-friendly framework that enables domain scientists to generate 3D animations of petascale, time-varying climate data on commodity hardware using an LLM-assisted conversational interface, thereby eliminating the need for specialized visualization expertise and high-performance computing resources.
This paper proposes a bi-directional digital twin prototype anchoring framework enhanced with multi-periodicity learning to achieve robust few-shot fault diagnosis by leveraging meta-training in a virtual simulation space and test-time adaptation in the physical domain, thereby overcoming the limitations of traditional methods that require abundant labeled or unlabeled target data.
MedSteer is a training-free activation-steering framework that generates structurally preserved counterfactual endoscopic images by manipulating cross-attention activations in diffusion transformers, outperforming existing methods in concept editing and downstream medical detection tasks.
