Evaluating the Disentanglement of Deep Generative Models through Manifold Topology

ICLR 2021poster

Learning disentangled representations is regarded as a fundamental task for improving the generalization, robustness, and interpretability of generative models. However, measuring disentanglement has been challenging and inconsistent, often dependent on an ad-hoc external model or specific to a cert…

Countdown Regression: Sharp and Calibrated Survival Predictions

UAI 2019poster

Probabilistic survival predictions (i.e. personalized survival curves) from models trained with Maximum Likelihood Estimation (MLE) can have high, and sometimes unacceptably high variance. The field of meteorology, where the paradigm of maximizing sharpness subject to calibration is popular, has ad…

HYPE: A Benchmark for Human eYe Perceptual Evaluation of Generative Models

NeurIPS 2019oral

Generative models often use human evaluations to measure the perceived quality of their outputs. Automated metrics are noisy indirect proxies, because they rely on heuristics or pretrained embeddings. However, up until now, direct human evaluation strategies have been ad-hoc, neither standardized no…
