EviSeek: An Evidence-Centric Agentic Framework for Embodied Active Information Seeking

Read the original on arXiv AI →

EviSeek is a training‑free framework that explicitly links question‑derived evidence demands to observation‑conditioned actions and selective evidence retention. By making the informational purpose of interaction explicit, it guides agents to acquire only the evidence needed to answer a question. On the ESI‑Bench dataset, EviSeek improves accuracy by 7.1 percentage points over a single‑model agent with Qwen3‑VL‑32B and by 3.7 points with Gemini 3.1 Pro, while also boosting visual‑support‑weighted accuracy and reducing token usage.

JRDB-AVR: An Active Visual Reasoning Benchmark for Embodied Agents in Real-World Environments

JRDB-AVR is a new benchmark for embodied agents that tests active visual reasoning in real-world environments. It requires agents to answer questions by requesting limited observations in time and view, and evaluates both the final answer and the visual evidence that supports it. The benchmark includes diverse tasks such as temporal search, viewpoint selection, and human-oriented compositional reasoning, and introduces a reference agent that builds an observation‑grounded graph world model.

Iron: Intent-Aligned and Retrospective Dual Learning Framework for Enhancing Generalist Virtual Agents

Iron is a new framework for training generalist virtual agents that aligns low‑level actions with high‑level intents using a stepwise cycle‑consistent reward. It also repurposes failed trajectories through a hindsight reproduction mechanism to improve learning efficiency and task diversity. Experiments show Iron‑trained agents outperform those trained with three times more data, achieving a 25.06% relative improvement on unseen web tasks and better performance on complex tasks.

UESF-Bench: Benchmarking and Probing for Unified Embodied Seeking and Following

arXiv:2607. 13621v1 Announce Type: new Abstract: Language-guided human following is an important capability for embodied agents, but existing benchmarks typically assume that the target person is visible at the start of an episode.
