Spurious Rewards: Rethinking Training Signals in RLVR

arXiv:2506.10947v2 Announce Type: replace-cross Abstract: We show that reinforcement learning with verifiable rewards (RLVR) can elicit strong mathematical reasoning in certain language models even with spurious rewards that have little, no, or even negative correlation with the correct answer. For…

Optimizer choice matters for the emergence of Neural Collapse

arXiv:2602.16642v3 Announce Type: replace Abstract: Neural Collapse (NC) refers to the emergence of highly symmetric geometric structures in the representations of deep neural networks during the terminal phase of training. Despite its prevalence, the theoretical understanding of NC remains limited.…

Overparameterized Multiple Linear Regression as Hyper-Curve Fitting

arXiv:2404.07849v2 Announce Type: replace-cross Abstract: This work demonstrates that applying a fixed-effect multiple linear regression (MLR) model to an overparameterized dataset is mathematically equivalent to fitting a hyper-curve parameterized by a single scalar. This reformulation shifts the focus from global…

Quantum enhanced ensemble GANs for anomaly detection in continuous biomanufacturing

arXiv:2508.21438v2 Announce Type: replace Abstract: The development of continuous biomanufacturing processes requires robust and early anomaly detection, since even minor deviations can compromise yield and stability, leading to disruptions in scheduling, reduced weekly production, and diminished economic performance. These processes…

NTK-Guided Implicit Neural Teaching

arXiv:2511.15487v2 Announce Type: replace Abstract: Implicit Neural Representations (INRs) parameterize continuous signals via multilayer perceptrons (MLPs), enabling compact, resolution-independent modeling for tasks like image, audio, and 3D reconstruction. However, fitting high-resolution signals demands optimizing over millions of coordinates, incurring prohibitive…

Coarsening Bias from Variable Discretization in Causal Functionals

arXiv:2602.22083v1 Announce Type: cross Abstract: A class of causal effect functionals requires integration over conditional densities of continuous variables, as in mediation effects and nonparametric identification in causal graphical models. Estimating such densities and evaluating the resulting integrals can be…

SymTorch: A Framework for Symbolic Distillation of Deep Neural Networks

arXiv:2602.21307v1 Announce Type: new Abstract: Symbolic distillation replaces neural networks, or components thereof, with interpretable, closed-form mathematical expressions. This approach has shown promise in discovering physical laws and mathematical relationships directly from trained deep learning models, yet adoption remains limited…
