Learning in Stackelberg Mean Field Games: A Non-Asymptotic Analysis

arXiv:2509.15392v1 Announce Type: new Abstract: We study policy optimization in Stackelberg mean field games (MFGs), a hierarchical framework for modeling the strategic interaction between a single leader and an infinitely large population of homogeneous followers. The objective can be formulated…

cadrille: Multi-modal CAD Reconstruction with Online Reinforcement Learning

arXiv:2505.22914v2 Announce Type: replace-cross Abstract: Computer-Aided Design (CAD) plays a central role in engineering and manufacturing, making it possible to create precise and editable 3D models. Using a variety of sensor or user-provided data as inputs for CAD reconstruction can…

VoXtream: Full-Stream Text-to-Speech with Extremely Low Latency

arXiv:2509.15969v1 Announce Type: cross Abstract: We present VoXtream, a fully autoregressive, zero-shot streaming text-to-speech (TTS) system for real-time use that begins speaking from the first word. VoXtream directly maps incoming phonemes to audio tokens using a monotonic alignment scheme and…

Top-$k$ Feature Importance Ranking

arXiv:2509.15420v1 Announce Type: new Abstract: Accurate ranking of important features is a fundamental challenge in interpretable machine learning with critical applications in scientific discovery and decision-making. Unlike feature selection and feature importance, the specific problem of ranking important features has…

Random Matrix Theory-guided sparse PCA for single-cell RNA-seq data

arXiv:2509.15429v1 Announce Type: new Abstract: Single-cell RNA-seq provides detailed molecular snapshots of individual cells but is notoriously noisy. Variability stems from biological differences, PCR amplification bias, limited sequencing depth, and low capture efficiency, making it challenging to adapt computational pipelines…
