Eshan Ehsan Abbasnejad

Research interests: Machine Learning, Information Retrieval, Graphical Models, Approximate Inference, Non-parametric Bayesian Methods, Recommender Systems, and Decision Theory.

Project Title:  Decision-theoretic Approximations for Machine Learning

Most machine learning algorithms focus on either learning the probabilistic model or minimizing the loss. In probabilistic models, approximate inference, the process of obtaining the desired model from the observations when its is not tractable, does not consider the task loss. On the other end of the spectrum, the common practice in learning is to minimize the task loss without considering the uncertainty of prediction model. Therefore, we investigate the intersection of decision theory and machine learning considering both uncertainty in prediction model and the task loss.

Research interests: smart predictions and modeling by the application of machine learning and data mining techniques.

Project Title: Time-varying Dynamic Bayesian Causal Networks for Moving Objects

To learn the periodic behaviors of moving objects, e.g., traffic, and to infer their correlations are essential knowledge related to our daily life.  The popularity of spatial-temporal-aware equipments allow the collection of trajectories in unprecedented scale.  Depending on the type of moving objects, their trajectories might exhibit unfavorable statistical properties, e.g., data sparseness and skewness, and heterogeneous data patterns, etc.  To address the problems, we aim to reveal the moving objects' view of areas by learning regions directly from their trajectories based on unsupervised machine learning techniques, and to capture the evolution of region structure by using a time-varying model.  Upon satisfying causal Markov assumption, causal inference can be made.
