Mitigating Hallucinations in Large Language Models via Causal Reasoning

arXiv:2508.12495v2 Announce Type: replace-cross Abstract: Large language models (LLMs) exhibit logically inconsistent hallucinations that appear coherent yet violate reasoning principles, with recent research suggesting an inverse relationship between causal reasoning capabilities and such hallucinations. However, existing reasoning approaches in LLMs,…

Hey Pentti, We Did (More of) It!: A Vector-Symbolic Lisp With Residue Arithmetic

arXiv:2511.08767v1 Announce Type: new Abstract: Using Frequency-domain Holographic Reduced Representations (FHRRs), we extend a Vector-Symbolic Architecture (VSA) encoding of Lisp 1.5 with primitives for arithmetic operations using Residue Hyperdimensional Computing (RHC). Encoding a Turing-complete syntax over a high-dimensional vector space…

A Generalized Bias-Variance Decomposition for Bregman Divergences

arXiv:2511.08789v1 Announce Type: new Abstract: The bias-variance decomposition is a central result in statistics and machine learning, but is typically presented only for the squared error. We present a generalization of the bias-variance decomposition where the prediction error is a…

IFG: Internet-Scale Guidance for Functional Grasping Generation

arXiv:2511.09558v1 Announce Type: cross Abstract: Large Vision Models trained on internet-scale data have demonstrated strong capabilities in segmenting and semantically understanding object parts, even in cluttered, crowded scenes. However, while these models can direct a robot toward the general region…

BayesQ: Uncertainty-Guided Bayesian Quantization

arXiv:2511.08821v1 Announce Type: new Abstract: We present BayesQ, an uncertainty-guided post-training quantization framework that is the first to optimize quantization under the posterior expected loss. BayesQ fits a lightweight Gaussian posterior over weights (diagonal Laplace by default; optional K-FAC/low-rank), whitens…

Physics-Informed Machine Learning for Characterizing System Stability

arXiv:2511.08831v1 Announce Type: new Abstract: In the design and operation of complex dynamical systems, it is essential to ensure that all state trajectories of the dynamical system converge to a desired equilibrium within a guaranteed stability region. Yet, for many…

Solver-Free Decision-Focused Learning for Linear Optimization Problems

arXiv:2505.22224v2 Announce Type: replace Abstract: Mathematical optimization is a fundamental tool for decision-making in a wide range of applications. However, in many real-world scenarios, the parameters of the optimization problem are not known a priori and must be predicted from…
