In this research we present a novel approach to the concept change detection problem. Change detection is a fundamental issue with data stream mining as classification models …
We present AROW, an online learning algorithm for binary and multiclass problems that combines large margin training, confidence weighting, and the capacity to handle non …
Collaborative filtering (CF) aims to predict users' ratings on items according to historical user- item preference data. In many real-world applications, preference data are usually sparse …
Reinforcement Learning (RL) has achieved remarkable success in safety-critical areas, but it can be weakened by adversarial attacks. Recent studies have introduced``smoothed …
Confidence-weighted online learning is a generalization of margin-based learning of linear classifiers in which the margin constraint is replaced by a probabilistic constraint based on a …
We develop an approach to risk minimization and stochastic optimization that provides a convex surrogate for variance, allowing near-optimal and computationally efficient trading …
Though machine learning algorithms excel at minimizing the average loss over a population, this might lead to large discrepancies between the losses across groups within …
