Universal Marginaliser for Deep Amortised Inference for Probabilistic Programs

no code implementations16 Oct 2019 Robert Walecki, Kostis Gourgoulias, Adam Baker, Chris Hart, Chris Lucas, Max Zwiessele, Albert Buchard, Maria Lomeli, Yura Perov, Saurabh Johri

Probabilistic programming languages (PPLs) are powerful modelling tools which allow to formalise our knowledge about the world and reason about its inherent uncertainty.

SEWA DB: A Rich Database for Audio-Visual Emotion and Sentiment Research in the Wild

no code implementations9 Jan 2019 Jean Kossaifi, Robert Walecki, Yannis Panagakis, Jie Shen, Maximilian Schmitt, Fabien Ringeval, Jing Han, Vedhas Pandit, Antoine Toisoul, Bjorn Schuller, Kam Star, Elnar Hajiyev, Maja Pantic

Natural human-computer interaction and audio-visual human behaviour sensing systems, which would achieve robust performance in-the-wild are more needed than ever as digital devices are increasingly becoming an indispensable part of our life.

Deep Structured Learning for Facial Action Unit Intensity Estimation

no code implementations CVPR 2017 Robert Walecki, Ognjen, Rudovic, Vladimir Pavlovic, Björn Schuller, Maja Pantic

The goal of this paper is to model these structures and estimate complex feature representations simultaneously by combining conditional random field (CRF) encoded AU dependencies with deep learning.

Copula Ordinal Regression for Joint Estimation of Facial Action Unit Intensity

no code implementations CVPR 2016 Robert Walecki, Ognjen Rudovic, Vladimir Pavlovic, Maja Pantic

Joint modeling of the intensity of facial action units (AUs) from face images is challenging due to the large number of AUs (30+) and their intensity levels (6).

Variable-state Latent Conditional Random Fields for Facial Expression Recognition and Action Unit Detection

no code implementations13 Oct 2015 Robert Walecki, Ognjen Rudovic, Vladimir Pavlovic, Maja Pantic

For instance, in the case of AU detection, the goal is to discriminate between the segments of an image sequence in which this AU is active or inactive.
