When Remembering and Planning are Worth it: Navigating under Change
Omid Madani, J. Brian Burns, Reza Eghbali +1
We explore how different types and uses of memory can aid spatial navigation in changing uncertain environments. In the simple foraging task we study, every day, our agent has to f…
Tracking Changing Probabilities via Dynamic Learners
Omid Madani
Consider a predictor, a learner, whose input is a stream of discrete items. The predictor's task, at every time point, is probabilistic multiclass prediction, i.e. to predict which…
Expedition: A System for the Unsupervised Learning of a Hierarchy of Concepts
Omid Madani
We present a system for bottom-up cumulative learning of myriad concepts corresponding to meaningful character strings, and their part-related and prediction edges. The learning is…
Binomial Tails for Community Analysis
Omid Madani, Thanh Ngo, Weifei Zeng +5
An important task of community discovery in networks is assessing significance of the results and robust ranking of the generated candidate groups. Often in practice, numerous cand…
ExplainIt! -- A declarative root-cause analysis engine for time series data (extended version)
Vimalkumar Jeyakumar, Omid Madani, Ali Parandeh +3
We present ExplainIt!, a declarative, unsupervised root-cause analysis engine that uses time series monitoring data from large complex systems such as data centres. ExplainIt! empo…
Polynomial Value Iteration Algorithms for Detrerminstic MDPs
Omid Madani
Value iteration is a commonly used and empirically competitive method in solving many Markov decision process problems. However, it is known that value iteration has only pseudo-po…
