Text-to-Any-Skeleton Motion Generation Without Retargeting

ICCV 2025poster

Recent advances in text-driven motion generation have shown notable advancements. However, these works are typically limited to standardized skeletons and rely on a cumbersome retargeting process to adapt to varying skeletal configurations of diverse characters. In this paper, we present OmniSkel, a…

On-the-fly Rectification for Robust Large-Vocabulary Topic Inference

ICML 2021spotlight

Across many data domains, co-occurrence statistics about the joint appearance of objects are powerfully informative. By transforming unsupervised learning problems into decompositions of co-occurrence statistics, spectral algorithms provide transparent and efficient algorithms for posterior inferenc…

Scaling Gaussian Process Regression with Derivatives

NeurIPS 2018poster

Gaussian processes (GPs) with derivatives are useful in many applications, including Bayesian optimization, implicit surface reconstruction, and terrain reconstruction. Fitting a GP to function values and derivatives at $n$ points in $d$ dimensions requires linear solves and log determinants with an…

Scalable Log Determinants for Gaussian Process Kernel Learning

NeurIPS 2017poster

For applications as varied as Bayesian neural networks, determinantal point processes, elliptical graphical models, and kernel learning for Gaussian processes (GPs), one must compute a log determinant of an n by n positive definite matrix, and its derivatives---leading to prohibitive O(n^3) computat…
