In recent years, research in Artificial Neural Networks (ANNs) has resurged, now under
the Deep-Learning umbrella, and grown extremely popular due to major breakthroughs
in methodological and computing capabilities. Deep-Learning methods are part of
representation-learning algorithms that attempt ...

Developing transparent predictive analytics has attracted significant research attention recently. There have been multiple theories on how to model learning transparency but none of them aims to understand the internal and often complicated modeling processes. In this paper we adopt a contemporary ...

Data science is penetrating virtually every aspect of our society. However, data science algorithms and systems, including data acquisition and processing pipelines and analytical techniques, are becoming increasingly complex. Many data science algorithms and systems are not transparent to the end-u ...

We consider two widely used notions in machine learning, namely: sparsity and stability. Both notions are deemed desirable, and are believed to lead to good generalization ability. We show that these two notions contradict each other: a sparse algorithm can not be stable and vice versa. Thus, one ha ...

We consider a robust classification problem and show that standard regularized
SVM is a special case of our formulation, providing an explicit link between reg-
ularization and robustness. At the same time, the physical connection of noise and
robustness suggests the potential for a broad new fami ...

Collaborative networks are composed of experts who cooperate with each other to complete specific tasks, such as resolving problems reported by customers. A task is posted and subsequently routed in the network from an expert to another until being resolved. When an expert cannot solve a task, his r ...

We present a framework for biclustering and clustering where the observations are general labels. Our approach is based on the maximum likelihood estimator and its convex relaxation, and generalizes recent works in graph clustering to the biclustering setting. In addition to standard biclustering se ...

Heterogeneous Information Network (HIN) is a natural and general
representation of data in modern large commercial recommender
systems which involve heterogeneous types of data. HIN based
recommenders face two problems: how to represent the high-level
semantics of recommendations and how to fuse ...
