Information Bottleneck Domain Adaptation with Privileged Information for Visual Recognition

We address the unsupervised domain adaptation problem for visual recognition when an auxiliary data view is available during training. This is important because it allows improving the training of visual classifiers on a new target visual domain when paired additional source data is cheaply available. This is the case when we learn from a source of RGB plus depth data, for then test on a new RG...

Auxiliary Training Information Assisted Visual Recognition

In the realm of multi-modal visual recognition, the reliability of the data acquisition system is often a concern due to the increased complexity of the sensors. One of the major issues is the accidental loss of one or more sensing channels, which poses a major challenge to current learning systems. In this paper, we examine one of these specific missing data problems, where we have a main moda...

Recognition of Visual Events using Spatio-Temporal Information of the Video Signal

Recognition of visual events as a video analysis task has become popular in machine learning community. While the traditional approaches for detection of video events have been used for a long time, the recently evolved deep learning based methods have revolutionized this area. They have enabled event recognition systems to achieve detection rates which were not reachable by traditional approac...

Mixed Bayesian Networks with Auxiliary Variables for Automatic Speech Recognition

In standard automatic speech recognition (ASR), hidden Markov models (HMMs) calculate their emission probabilities by an artificial neural network (ANN) or a Gaussian distribution conditioned only upon the hidden state variable. Recent work [12] showed the benefit of conditioning the emission distributions also upon a discrete auxiliary variable, which is observed in training and hidden in reco...
