Multi-Scale Label Relation Learning for Multi-Label Classification Using 1-Dimensional Convolutional Neural Networks

no code implementations13 Jul 2021 Junhyung Kim, Byungyoon Park, Charmgil Hong

By training a model with multiple kernel sizes, the method is able to learn the dependency relations among labels at multiple scales, while it uses a drastically smaller number of parameters.

Detection of Abnormal Input-Output Associations

no code implementations3 Aug 2017 Charmgil Hong, Si-Qi Liu, Milos Hauskrecht

We study a novel outlier detection problem that aims to identify abnormal input-output associations in data, whose instances consist of multi-dimensional input (context) and output (responses) pairs.

Detecting Unusual Input-Output Associations in Multivariate Conditional Data

no code implementations21 Dec 2016 Charmgil Hong, Milos Hauskrecht

We present a novel outlier detection framework that identifies abnormal input-output associations in data with the help of a decomposable conditional probabilistic model that is learned from all data instances.

Dealing with Class Imbalance using Thresholding

no code implementations10 Jul 2016 Charmgil Hong, Rumi Ghosh, Soundar Srinivasan

In advanced manufacturing units, where the manufacturing process has matured over time, the number of instances (or parts) of the product that need to be rejected (based on a strict regime of quality tests) becomes relatively rare and are defined as outliers.

MCODE: Multivariate Conditional Outlier Detection

no code implementations15 May 2015 Charmgil Hong, Milos Hauskrecht

Outlier detection aims to identify unusual data instances that deviate from expected patterns.

A Mixtures-of-Experts Framework for Multi-Label Classification

no code implementations16 Sep 2014 Charmgil Hong, Iyad Batal, Milos Hauskrecht

We develop a novel probabilistic approach for multi-label classification that is based on the mixtures-of-experts architecture combined with recently introduced conditional tree-structured Bayesian networks.
