MAEM: Mitigating Recency Bias via a Replay-Free, Capacity-Controlled Dynamic Mixture of Experts for Class-Incremental Graph Learning

This work proposes MAEM, a replay-free, capacity-controlled dynamic mixture-of-experts framework for class-incremental graph learning that mitigates recency bias, outperforms strong continual graph learning baselines, and keeps model capacity bounded under strict replay-free learning.

HGRP: Heterogeneous Graph Neural Network for Routability Prediction

HGRP models the cells, nets, and routing grids as distinct types of nodes and explicitly represents topological connectivity, spatial mapping, and grid adjacency, thereby constructing a heterogeneous graph representation that preserves multi-level circuit semantics.

Dimension-Optimal Dynamic Regret in Exp-Concave Online Learning

A proper, full-information learner on compact convex subsets of $\mathbb{R}^d$ that adapts to the unknown path length and, under fixed dimension-independent diameter, gradient, and curvature parameters, guarantees full information under fixed dimension-independent diameter, gradient, and curvature parameters.

RM-OPD: On-Policy Distillation for Generative Reward Models

Reinforcement Learning on Mixed-domain preference data (Mix-RL) has become the mainstream approach for training general-purpose Generative Reward Models (GRMs). However, Mix-RL suffers from two critical bottlenecks: the reward sparsity induced by outcome rewards, and the cross-domain interference arising from jointly o...

Optimizing Sparse Boolean Rule Networks using Mixed Integer Linear Programming

We study the problem of learning accurate and cognitively simple binary classifiers that are directly interpretable as Boolean rules. We propose mixed integer linear programming (MILP) formulations for training sparse disjunctive normal form (DNF) networks, viewed as small networks with a conjunctive hidden layer and a...

In-Context Batch Black-box Optimization via Flow Matching

Batch black-box optimization is important for expensive systems where many candidates can be evaluated in parallel, yet only a few rounds of evaluation are affordable. In this regime, effective batch construction must identify multiple promising regions while avoiding redundant evaluations, and conventional Bayesian op...

A Bregman Proximal Viewpoint on Neural Operators

We present several advances on neural operators by viewing the action of operator layers as the minimizers of Bregman regularized optimization problems over Banach function spaces. The proposed framework allows interpreting the activation operators as Bregman proximity operators from dual to primal space. This novel vi...

KANLab: TensorFlow Playground for Kolmogorov-Arnold Networks

KANLab is a browser-based visualization tool designed to interactively teach the core concepts of Kolmogorov-Arnold Networks (KAN), forked from the widely successful TensorFlow Playground. To maximize educational clarity, KANLab omits residual connections and learnable scaling parameters found in modern KAN implementat...

From Spectral to Frobenius: When Muon Loses Its Spectral Implicit Bias

It is proved that Muon can recover its spectral max-margin bias with Newton-Schulz iterations growing logarithmically over training, and disentangle the roles of Newton-Schulz iteration count, the stabilization constant, and the Newton-Schulz polynomial, revealing distinct asymptotic behaviors, including directions tha...

Exhaustive Canonical Skeletons Generation: A Formal Dataset for Decomposable Symbolic Regression

An exhaustive dataset of univariate canonical skeletons generated via a deterministic constrained context-free grammar designed to support the decomposable SR paradigm to solve multivariate SR problems without assuming linear separability is introduced.

What Do Foundation Models for Market Microstructure Learn? A Controlled Study with Synthetic Limit Order Books

Autoregressive transformers trained on limit order book (LOB) message streams are increasingly proposed as foundation models for market microstructure. Because the generative process of real markets is unknown, these models can be judged only by the realism of their output, leaving open what they actually learn. We mak...
