Efficient and Adaptive Simultaneous Speech Translation with Fully Unidirectional Architecture

AAAI 2026technical

Simultaneous speech translation (SimulST) produces translations incrementally while processing partial speech input. Although large language models (LLMs) have shown strong capabilities in offline translation tasks, applying them to SimulST poses notable challenges. Existing LLM-based SimulST appr

IterResearch: Rethinking Long-Horizon Agents via Markovian State Reconstruction

ICLR 2026poster

Recent advances in deep-research agents have shown promise for autonomous knowledge construction through dynamic reasoning over external sources. However, existing approaches rely on a mono-contextual paradigm that accumulates all information in a single, expanding context window, leading to context…

Fixing Distribution Shifts of LLM Self-Critique via On-Policy Self-Play Training

ACL 2025long

Self-critique mechanisms significantly improve the performance of language models in complex reasoning tasks by giving them the ability to correct errors, conduct induction and deduction, and switch thinking insights. However, synthetic data methods often require human-introduced errors or sampling…

Investigating Hallucinations in Simultaneous Machine Translation: Knowledge Distillation Solution and Components Analysis

NAACL 2025long

Simultaneous Machine Translation (SiMT) generates target translation before receiving the whole source sentence and faces a serious hallucination problem. In contrast, traditional offline machine translation (OMT) models exhibit significantly fewer hallucinations. Motivated by this disparity, we pro…

SimulPL: Aligning Human Preferences in Simultaneous Machine Translation

ICLR 2025poster

Simultaneous Machine Translation (SiMT) generates translations while receiving streaming source inputs. This requires the SiMT model to learn a read/write policy, deciding when to translate and when to wait for more source input. Numerous linguistic studies indicate that audiences in SiMT scenarios…

Teaching Vision-Language Models to Ask: Resolving Ambiguity in Visual Questions

ACL 2025long

In visual question answering (VQA) context, users often pose ambiguous questions to visual language models (VLMs) due to varying expression habits. Existing research addresses such ambiguities primarily by rephrasing questions. These approaches neglect the inherently interactive nature of user inter…

Large Language Models Know What is Key Visual Entity: An LLM-assisted Multimodal Retrieval for VQA

EMNLP 2024main

Visual question answering (VQA) tasks, often performed by visual language model (VLM), face challenges with long-tail knowledge. Recent retrieval-augmented VQA (RA-VQA) systems address this by retrieving and integrating external knowledge sources. However, these systems still suffer from redundant v…

Self-Modifying State Modeling for Simultaneous Machine Translation

ACL 2024long

Simultaneous Machine Translation (SiMT) generates target outputs while receiving stream source inputs and requires a read/write policy to decide whether to wait for the next source token or generate a new target token, whose decisions form a decision path. Existing SiMT methods, which learn the poli…
