Nonlinear Semi-Parametric Models for Survival Analysis
Chirag Nagpal, Rohan Sangave, Amit Chahar +3
Semi-parametric survival analysis methods like the Cox Proportional Hazards (CPH) regression (Cox, 1972) are a popular approach for survival analysis. These methods involve fitting…
Discovery of Complex Anomalous Patterns of Sexual Violence in El Salvador
Maria De-Arteaga, Artur Dubrawski
When sexual violence is a product of organized crime or social imaginary, the links between sexual violence episodes can be understood as a latent structure. With this assumption i…
Noise-Tolerant Interactive Learning from Pairwise Comparisons
Yichong Xu, Hongyang Zhang, Aarti Singh +2
We study the problem of interactively learning a binary classifier using noisy labeling and pairwise comparison oracles, where the comparison oracle answers which one in the given…
Suppressing Background Radiation Using Poisson Principal Component Analysis
P. Tandon, P. Huggins, A. Dubrawski +2
Performance of nuclear threat detection systems based on gamma-ray spectrometry often strongly depends on the ability to identify the part of measured signal that can be attributed…
Clustering on the Edge: Learning Structure in Graphs
Matt Barnes, Artur Dubrawski
With the recent popularity of graphical clustering methods, there has been an increased focus on the information between samples. We show how learning cluster structure using edge…
Batched Lazy Decision Trees
Mathieu Guillame-Bert, Artur Dubrawski
We introduce a batched lazy algorithm for supervised classification using decision trees. It avoids unnecessary visits to irrelevant nodes when it is used to make predictions with…
