MCTR: Multi Camera Tracking Transformer
Alexandru Niculescu-Mizil, Deep Patel, Iain Melvin
Multi-camera tracking plays a pivotal role in various real-world applications. While end-to-end methods have gained significant interest in single-camera tracking, multi-camera tra…
Hopper: Multi-hop Transformer for Spatiotemporal Reasoning
Honglu Zhou, Asim Kadav, Farley Lai +4
This paper considers the problem of spatiotemporal object-centric reasoning in videos. Central to our approach is the notion of object permanence, i.e., the ability to reason about…
Supervised Feature Subset Selection and Feature Ranking for Multivariate Time Series without Feature Extraction
Shuchu Han, Alexandru Niculescu-Mizil
We introduce supervised feature ranking and feature subset selection algorithms for multivariate time series (MTS) classification. Unlike most existing supervised/unsupervised feat…
Controlling the Precision-Recall Tradeoff in Differential Dependency Network Analysis
Diane Oyen, Alexandru Niculescu-Mizil, Rachel Ostroff +2
Graphical models have gained a lot of attention recently as a tool for learning and representing dependencies among variables in multivariate data. Often, domain scientists are loo…
Obtaining Calibrated Probabilities from Boosting
Alexandru Niculescu-Mizil, Richard A. Caruana
Boosted decision trees typically yield good accuracy, precision, and ROC area. However, because the outputs from boosting are not well calibrated posterior probabilities, boosting…
A Binary Classification Framework for Two-Stage Multiple Kernel Learning
Abhishek Kumar, Alexandru Niculescu-Mizil, Koray Kavukcuoglu +1
With the advent of kernel methods, automating the task of specifying a suitable kernel has become increasingly important. In this context, the Multiple Kernel Learning (MKL) proble…
