VISTA: A Test-Time Self-Improving Video Generation Agent

CVPR 2026

Despite rapid advances in text-to-video synthesis, generated video quality remains critically dependent on precise user prompts. Existing test-time optimization methods, successful in other domains, struggle with the multi-faceted nature of video. In this work, we introduce VISTA (Video Iterative Se

Neural Spline Search for Quantile Probabilistic Modeling

AAAI 2023technical

Accurate estimation of output quantiles is crucial in many use cases, where it is desired to model the range of possibility. Modeling target distribution at arbitrary quantile levels and at arbitrary input attribute levels are important to offer a comprehensive picture of the data, and requires the…

Nested Hierarchical Transformer: Towards Accurate, Data-Efficient and Interpretable Visual Understanding

AAAI 2022technical

Hierarchical structures are popular in recent vision transformers, however, they require sophisticated designs and massive datasets to work well. In this paper, we explore the idea of nesting basic local transformers on non-overlapping image blocks and aggregating them in a hierarchical way. We find…
