The humanoid robot Nexi and a team of robot helicopters are deployed in response to a simulated fire aboard a Navy ship. Working together with a remote human operator, the robots search for survivors and guide them to safety. A mixed-initiative tasking system allows the human operator to specify tea ...

Learning graphical models with hidden variables can offer semantic insights to complex data and lead to salient structured predictors without relying on expensive, sometime unattainable fully annotated training data. While likelihood-based methods have been extensively explored, to our knowledge, le ...

In this talk, I explore the mathematical relationships between duality in information geometry, convex analysis, and divergence functions.
First, from the fundamental inequality of a convex function, a family of divergence measures can be constructed, which specializes to the familiar Bregman diver ...

Distributed reinforcement learning (DRL) has been studied as an approach to learn control policies thorough interactions between distributed agents and environments. The main emphasis of DRL has been put on the way to learn sub-optimal policies with the least or limited sharing of agents' perception ...

Graph transduction methods label input data by learning a classification function that is regularized to exhibit smoothness along a graph over labeled and unlabeled samples. In practice, these algorithms are sensitive to the initial set of labels provided by the user. For instance, classification ac ...

Learning sparse Markov networks based on the maximum margin principle remains an open problem in structured prediction. In this paper, we proposed the Laplace max-margin Markov network (LapM3N), and a general class of Bayesian M3N (BM3N) of which the LapM3N is a special case and enjoys a sparse repr ...

Supervised topic models utilize document’s side information for discovering predictive low dimensional representations of documents;
and existing models apply likelihood-based estimation. In this paper, we present a max-margin supervised topic model for both continuous
and categorical response var ...

Sparsity is a desirable property in high dimensional learning. The $\ell_1$-norm regularization can lead to primal sparsity, while max-margin methods achieve dual sparsity; but achieving both in a single structured prediction model remains difficult. This paper presents an $\ell_1$-norm max-margin M ...

Recent work has shown the effectiveness of leveraging layout and tag-tree structure for segmenting webpages and labeling HTML elements. However, how to effectively segment and label the text contents inside HTML elements is still an open problem. Since many text contents on a webpage are often text ...
