Switched Latent Force Models for Movement ... March 28, 2011 Latent force models encode the interaction between multiple related dynamical systems in the form of a kernel or covariance function. Each variable to be modeled is represented as the output of a ...

Learning invariant features using the ... March 28, 2011 Identifying the features of objects becomes a challenge when those features can change in their appearance. We introduce the Transformed Indian Buffet Process (tIBP), and use it to define a ...

Online Markov Decision Processes under Bandit ... March 28, 2011 We consider online learning in finite stochastic Markovian environments where in each time step a new reward function is chosen by an oblivious adversary. The goal of the learning agent is to ...

Structured Determinantal Point Processes March 28, 2011 We present a novel probabilistic model for distributions over sets of structures — for example, sets of sequences, trees, or graphs. The critical characteristic of our model is a ...

Global Analytic Solution for Variational Bayesian March 28, 2011 Bayesian methods of matrix factorization (MF) have been actively explored recently as promising alternatives to classical singular value decomposition. In this paper, we show that, despite the ...

Optimal Bayesian Recommendation Sets and ... March 28, 2011 Bayesian approaches to utility elicitation typically adopt (myopic) expected value of information (EVOI) as a natural criterion for selecting queries. However, EVOI-optimization is usually ...

Worst-case bounds on the quality of ... March 28, 2011 We study worst-case bounds on the quality of any fixed point assignment of the max-product algorithm for Markov Random Fields (MRF). We start proving a bound independent of the MRF structure and ...

Lecture 11 - Paris and the Belle Époque March 28, 2011 Modern Paris was indelibly shaped by the rebuilding project ordered by Napoleon III and carried out by Baron Haussmann in the 1850s and '60s. The large-scale demolition of whole ...

Variational Inference over Combinatorial Spaces March 26, 2011 Since the discovery of sophisticated fully polynomial randomized algorithms for a range of #P problems (Karzanov et al., 1991; Jerrum et al., 2001; Wilson, 2004), theoretical work on approximate ...

Supervised Clustering March 26, 2011 Despite the ubiquity of clustering as a tool in unsupervised learning, there is not yet a consensus on a formal theory, and the vast majority of work in this direction has focused on unsupervised ...

Learning To Count Objects in Images March 26, 2011 We propose a new supervised learning framework for visual object counting tasks, such as estimating the number of cells in a microscopic image or the number of humans in surveillance video ...
