Human Activity Recognition Using Objects

The computer vision endeavour of activity recognition from video has wide-ranging potential applications, from the monitoring of elderly people at home to shopping centre security systems. In this talk I'll describe the approach we're taking to this task: inferring a person's activity from the way they use objects in the environment. I'll introduce how we break the problem down in to three levels (object tracking, action primitive extraction, and high-level activity modelling), give an overview of our approach to each one (with demos in some cases), and explain some future directions.

A Trajectory Mixture Density Network for the Acoustic-articulatory Inversion Mapping

This talk presents work which appeared at the recent Interspeech 2006 conference. A trajectory model is proposed which is based on a mixture density network trained with target features augmented with dynamic features. This is then combined with an algorithm for estimating maximum likelihood trajectories which respects constraints between the static and derived dynamic features. I evaluated this model on an inversion mapping task. The introduction of the trajectory model successfully reduced root mean square error by up to 7.5%, as well as increasing correlation scores.

Multichannel dialogue act decoding of multiparty meetings

A number of authors have considered the task of dialogue act (DA) decoding for multiparty meetings, suggesting that information about the structure of the interaction (i.e. the sequence of statements, questions, interuptions etc) should prove useful in subsequent processing steps.

Previous approaches have typically considered each channel (speaker) in isolation when performing inference.

In this talk I present a framework for performing full joint classification and segmentation of all channels together. I take a multi-stream modelling approach using dynamic Bayesian networks (DBNs), with a state stream for each channel, and observations in the form of virtual evidence (VE), which consists of posteriors from conditional random fields (CRFs).

This is work in progress, and arose from discussions with Matthias Zimmermann after this year's MLMI.

Stick-breaking Construction for the Indian Buffet Process

The Indian buffet Process (IBP) is a recently proposed latent feature model where each object is modelled using a potentially unbounded number of binary latent features. It has had a variety of applications, including matrix factorization, causal inference, and psychological choice modelling. However, due to the unbounded nature of the model, standard Markov chain Monte Carlo inference techniques like Gibbs sampling is cumbersome and inefficient in IBPs. In this talk, I will reformulate the IBP model using a stick-breaking construction, and show that this leads to straightforward and efficient MCMC inference for the IBP. Furthermore, we will see that there are interesting and strong connections between the stick-breaking construction for the IBP, and the standard stick-breaking construction for the more well-known Dirichlet process.

There is another talk by the same speaker at 3.30pm in the same venue: A Bayesian Interpretation of Interpolated Kneser-Ney

UK Autumn School–Software Carpentry for Audio and Music Researchers

The aim of this one-week Autumn School (London, UK, 1-5 November 2010) is to train PhD students and researchers in the software development skills required to build reliable research software quickly and with a minimum of effort, and so maximize the impact of their research.

The Autumn School is presented by Dr. Greg Wilson in collaboration with SoundSoftware .ac.uk: Sustainable Software for Audio and Music Research.
