Fast Single-Class Classification and the Principle of Logit Separation
Gil Keren, Sivan Sabato, Björn Schuller
We consider neural network training, in applications in which there are many possible classes, but at test-time, the task is a binary classification task of determining whether the…
Temporal anomaly detection: calibrating the surprise
Eyal Gutflaish, Aryeh Kontorovich, Sivan Sabato +2
We propose a hybrid approach to temporal anomaly detection in access data of users to databases --- or more generally, any kind of subject-object co-occurrence data. We consider a…
Nearest-Neighbor Sample Compression: Efficiency, Consistency, Infinite Dimensions
Aryeh Kontorovich, Sivan Sabato, Roi Weiss
We examine the Bayes-consistency of a recently proposed 1-nearest-neighbor-based multiclass learning algorithm. This algorithm is derived from sample compression bounds and enjoys…
Selecting with History
Tom Hess, Sivan Sabato
We define a new selection problem, \emph{Selecting with History}, which extends the secretary problem to a setting with historical information. We propose a strategy for this probl…
