This paper introduces Adam-Aware In-Run Data Shapley, a novel method that overcomes the limitations of SGD-based attribution in adaptive optimizers by deriving a closed-form approximation and a Linearized Ghost Approximation to achieve near-perfect fidelity in data contribution estimation while maintaining high training efficiency.
This paper investigates whether Schwartz higher-order values improve sentence-level human value detection, finding that while hierarchical gating offers limited benefits, calibration techniques and hybrid ensembles significantly boost performance, suggesting the value hierarchy is more effective as an inductive bias than a rigid routing mechanism.
This paper introduces LatentMem, a learnable multi-agent memory framework that addresses memory homogenization and information overload by using an experience bank and a memory composer to generate customized, token-efficient latent memories, further optimized via Latent Memory Policy Optimization (LMPO) to significantly enhance multi-agent system performance.
This paper introduces T2T (Thickening-to-Thinning), a dynamic reward shaping framework inspired by human learning dynamics that enhances LLM reasoning by encouraging longer, exploratory trajectories on incorrect attempts and penalizing length upon success, thereby outperforming standard baselines on mathematical benchmarks.
This paper introduces a novel inference-time backdoor attack that exploits maliciously modified chat templates to compromise open-weight language models without altering weights or training data, demonstrating high success rates in degrading factual accuracy and inducing harmful outputs while evading current security scans.
This paper introduces the Hinge Regression Tree (HRT), a novel oblique decision tree method that reframes split learning as a non-linear least-squares problem solvable via a damped Newton method, offering provable convergence, universal approximation capabilities, and superior performance with compact structures compared to existing baselines.
This paper introduces Radial Müntz-Szász Networks (RMN), a highly parameter-efficient neural architecture that utilizes learnable radial power bases and a log-primitive to accurately model multidimensional singular fields like $1/r\log r$, achieving significantly lower error rates than standard MLPs and SIREN on benchmark tasks while providing closed-form gradients for physics-informed learning.
SDFed is a heterogeneous federated prompt learning framework that addresses local-global discrepancies by combining a fixed-length global prompt with variable-length local prompts, enhanced by subspace refinement and divergence control strategies to improve performance and robustness in privacy-sensitive, resource-constrained multi-party settings.
This paper identifies and formalizes "Retrieval Pivot Attacks" in Hybrid RAG systems, demonstrating how vector-retrieved seeds can inadvertently pivot through knowledge graph links to cause cross-tenant data leakage, and proves that enforcing authorization specifically at the graph expansion boundary effectively mitigates this risk with minimal overhead.
This paper proposes a unified diffusion-guided pretraining framework for brain graph foundation models that overcomes the limitations of existing methods by using diffusion to preserve semantic connectivity patterns during augmentation and to enable topology-aware global reconstruction, thereby achieving robust and transferable representations across diverse neuroimaging datasets.
This paper investigates document page reordering in heterogeneous Dutch freedom of information releases, identifying that while specialized models achieve high accuracy on short documents, seq2seq transformers fail to generalize to longer texts due to fundamental differences in required ordering strategies, a challenge effectively addressed through model specialization rather than curriculum learning.
This paper introduces a response-free framework that leverages natural language processing and topic modeling to automatically simplify psychological scales by identifying semantic latent structures, achieving an average 60.5% reduction in item count while preserving psychometric validity and construct alignment.
TrasMuon is a novel optimizer that enhances the stability and convergence of Muon-style methods by integrating global RMS calibration and energy-based trust-region clipping to preserve near-isometric geometry while mitigating sensitivity to step-size hyperparameters and high-energy outliers.
