Process-Supervised Reinforcement Learning for Interactive Multimodal Tool-Use Agents

Weiting Tan, Xinghua Qu, Ming Tu +4

Effective interactive tool use requires agents to master Tool Integrated Reasoning (TIR): a complex process involving multi-turn planning and long-context dialogue management. To t…

Streaming Sequence Transduction through Dynamic Compression

Weiting Tan, Yunmo Chen, Tongfei Chen +5

We introduce STAR (Stream Transduction with Anchor Representations), a novel Transformer-based model designed for efficient sequence-to-sequence transduction over streams. STAR dyn…

SSR: Alignment-Aware Modality Connector for Speech Language Models

Weiting Tan, Hirofumi Inaguma, Ning Dong +2

Fusing speech into pre-trained language model (SpeechLM) usually suffers from inefficient encoding of long-form speech and catastrophic forgetting of pre-trained text modality. We…

Upsample or Upweight? Balanced Training on Heavily Imbalanced Datasets

Tianjian Li, Haoran Xu, Weiting Tan +2

Data abundance across different domains exhibits a long-tailed distribution: few domains have abundant data, while most face data scarcity. Our work focuses on a multilingual setti…

DiffNorm: Self-Supervised Normalization for Non-autoregressive Speech-to-speech Translation

Weiting Tan, Jingyu Zhang, Lingfeng Shen +2

Non-autoregressive Transformers (NATs) are recently applied in direct speech-to-speech translation systems, which convert speech across different languages without intermediate tex…
