REALISTA: Realistic Latent Adversarial Attacks that Elicit LLM Hallucinations

ICML 2026poster

Large language models (LLMs) achieve strong performance across many tasks but remain vulnerable to hallucinations, motivating the need to find adversarial prompts that realistically elicit such failures. We formulate hallucination elicitation as a constrained optimization problem, where the goal is …

Voyaging into Perpetual Dynamic Scenes from a Single View

ICCV 2025poster

The problem of generating a perpetual dynamic scene from a single view is an important problem with widespread applications in augmented and virtual reality, and robotics. However, since dynamic scenes regularly change over time, a key challenge is to ensure that different generated views be consist…

Semantic Flow: Learning Semantic Fields of Dynamic Scenes from Monocular Videos

ICLR 2024poster

In this work, we pioneer Semantic Flow, a neural semantic representation of dynamic scenes from monocular videos. In contrast to previous NeRF methods that reconstruct dynamic scenes from the colors and volume densities of individual points, Semantic Flow learns semantics from continuous flows that…

MonoNeRF: Learning a Generalizable Dynamic Radiance Field from Monocular Videos

ICCV 2023poster

In this paper, we target at the problem of learning a generalizable dynamic radiance field from monocular videos. Different from most existing NeRF methods that are based on multiple views, monocular videos only contain one view at each timestamp, thereby suffering from ambiguity along the view dire…
