VSTAR: Generative Temporal Nursing for Longer Dynamic Video Synthesis

ICLR 2025poster

Despite tremendous progress in the field of text-to-video (T2V) synthesis, open-sourced T2V diffusion models struggle to generate longer videos with dynamically varying and evolving content. They tend to synthesize quasi-static videos, ignoring the necessary visual change-over-time implied in the te…

Multi-Class Uncertainty Calibration via Mutual Information Maximization-based Binning

ICLR 2021poster

Post-hoc multi-class calibration is a common approach for providing high-quality confidence estimates of deep neural network predictions. Recent work has shown that widely used scaling methods underestimate their calibration error, while alternative Histogram Binning (HB) methods often fail to prese…

The Power of Ensembles for Active Learning in Image Classification

CVPR 2018poster

Deep learning methods have become the de-facto standard for challenging image processing tasks such as image classification. One major hurdle of deep learning approaches is that large sets of labeled data are necessary, which can be prohibitively costly to obtain, particularly in medical image diagn…
