In a variety of domains it is desirable to learn a representation of an environment defined by a stream of sensori-motor experience. In many cases such a representation is necessary as the observational data is too plentiful to be stored in a computationally feasible way.

This talk proposes a theory of how conscious emotional experience is produced by the brain as the result of many interacting brain areas coordinated in working memory.

Using adaptive consultation of experts to improve convergence rates in multiagent learning

Speaker: Greg Hines

In this paper we study the use of experts algorithms in a multiagent setting.

A CAPTCHA is a special kind of AI hard test to prevent bots from logging into computer systems. We define an AI hard test to be a problem which is intractable for a computer to solve as a matter of general consensus of the AI community.

Common machine learning theory makes some simplifying assumptions about the learning set up. A problematic such simplification is the assumption that the data available to the learner for training is a faithful representative of the data it will be later tested on.

Most of text data mining techniques are based on either a word analysis or phrase analysis of the text. The statistical analysis of a term (word or phrase) frequency captures the importance of the term within a document. However, to achieve a more accurate analysis, the underlying mining technique should indicate terms that capture the semantics of the text from which the importance of a term in a sentence and in the document can be derived.

As an emerging field of study, granular computing has received much attention. Many models, frameworks, methods and techniques have been proposed and studied. It is perhaps the time to seek for a general and unified view so that fundamental issues can be examined and clarified. This talk examines granular computing from three perspectives.

Planning in partially observable domains is a notoriously difficult problem. However, in many real-world scenarios, planning can be simplified by decomposing the task into a hierarchy of smaller planning problems. Several approaches have been proposed to optimize a policy that decomposes according to a hierarchy specified a priori. In this thesis, I investigate the problem of automatically discovering the hierarchy.

Sports fans in many sports anxiously watch their team's performances and their chances of winning a championship or securing a playoff spot. Typically, they obtain their information from major newspapers and websites, which publish standings along with remarks on the qualification and elimination of the individual teams.
