OVI-MAP: Open-Vocabulary Instance-Semantic Mapping

Zilong Deng, Federico Tombari, Marc Pollefeys, Johanna Wald, Daniel Barath

CVPR 2026

Incremental open-vocabulary 3D instance-semantic mapping is essential for autonomous agents operating in complex everyday environments. However, it remains challenging due to the need for robust instance segmentation, real-time processing, and flexible open-set reasoning. Existing methods often rely

Near-Optimal Sample Complexity for Iterated CVaR Reinforcement Learning with a Generative Model

Zilong Deng, Simon Khan, Shaofeng Zou

AISTATS 2025poster

In this work, we study the sample complexity problem of risk-sensitive Reinforcement Learning (RL) with a generative model, where we aim to maximize the Conditional Value at Risk (CVaR) with risk tolerance level $\tau$ at each step, named Iterated CVaR. We develop nearly matching upper and lower…
