Effective User-defined Keyword Spotting with Dual-stage Matching, Multi-modal Enrollment, and Continual Adaptation
Zhiqi Ai, Han Cheng, Shiyi Mu +3
User-defined keyword spotting (KWS) is crucial for personalized voice interaction, yet existing methods face several challenges: (1) insufficient discriminability among confusable…
The -boundedness of wave operators for higher order Schrödinger operator with zero singularities in low odd dimensions
Han Cheng, Avy Soffer, Zhao Wu +1
This paper investigates the -bounds of wave operators for higher-order Schrödinger operators on , with and real-valued decaying pote…
Human Semantic Segmentation using Millimeter-Wave Radar Sparse Point Clouds
Pengfei Song, Luoyu Mei, Han Cheng
This paper presents a framework for semantic segmentation on sparse sequential point clouds of millimeter-wave radar. Compared with cameras and lidars, millimeter-wave radars have…
Dispersive estimates for the Schrödinger equation with finite rank perturbations
Han Cheng, Shanlin Huang, Quan Zheng
In this paper, we investigate dispersive estimates for the time evolution of Hamiltonians $$ H=-Î+\sum_{j=1}^N\langle\cdot\,, Ï_j\rangle Ï_j\quad\,\,\,\text{in}\,\,\,\mathbb{R}^…
Step 3.5 Flash: Open Frontier-Level Intelligence with 11B Active Parameters
Ailin Huang, Ang Li, Aobo Kong +213
We introduce Step 3.5 Flash, a sparse Mixture-of-Experts (MoE) model that bridges frontier-level agentic intelligence and computational efficiency. We focus on what matters most wh…
Towards Robustness Analysis of E-Commerce Ranking System
Ningfei Wang, Yupin Huang, Han Cheng +3
Information retrieval (IR) is a pivotal component in various applications. Recent advances in machine learning (ML) have enabled the integration of ML algorithms into IR, particula…
