Implicit Neural Representation Inference for Low-Dimensional Bayesian Deep Learning

ICLR 2024poster

Bayesian inference is the standard for providing full predictive distributions with well calibrated uncertainty estimates. However, scaling to a modern, overparameterized deep learning setting typically comes at the cost of severe and restrictive approximations, sacrificing model predictive stren…

Composition of Motion from Video Animation Through Learning Local Transformations

ICASSP 2023accepted

In this work, we solve the problem of motion representation in videos, according to local transformations applied to specific keypoints extracted from static the images. First, we compute the co-ordinates of the keypoints of the body or face through a pre-trained model, and then we introduce a convo…

Wind: Wasserstein Inception Distance For Evaluating Generative Adversarial Network Performance

ICASSP 2020accepted

In this paper, we present Wasserstein Inception Distance (WInD), a novel metric for evaluating performance of Generative Adversarial Networks (GANs). The proposed metric extends on the rationale of the previously proposed Frechet Inception Distance (FID), in the sense that GAN performance is quantif…
