Supervised Feature Subset Selection and Feature Ranking for Multivariate Time Series without Feature Extraction

no code implementations1 May 2020 Shuchu Han, Alexandru Niculescu-Mizil

We introduce supervised feature ranking and feature subset selection algorithms for multivariate time series (MTS) classification.

On Separability of Loss Functions, and Revisiting Discriminative Vs Generative Models

no code implementations NeurIPS 2017 Adarsh Prasad, Alexandru Niculescu-Mizil, Pradeep K. Ravikumar

We revisit the classical analysis of generative vs discriminative models for general exponential families, and high-dimensional settings.

Controlling the Precision-Recall Tradeoff in Differential Dependency Network Analysis

no code implementations9 Jul 2013 Diane Oyen, Alexandru Niculescu-Mizil, Rachel Ostroff, Alex Stewart, Vincent P. Clark

We then show that by imposing a bias towards learning similar dependency networks for each condition the false discovery rates can be reduced to acceptable levels, at the cost of finding a reduced number of differences.

no code implementations NeurIPS 2012 Siddharth Gopal, Yiming Yang, Bing Bai, Alexandru Niculescu-Mizil

A challenging problem in hierarchical classification is to leverage the hierarchical relations among classes for improving classification performance.
