Directionally Dependent Multi-View Clustering Using Copula Model

no code implementations17 Mar 2020 Kahkashan Afrin, Ashif S. Iquebal, Mostafa Karimi, Allyson Souris, Se Yoon Lee, Bani K. Mallick

Motivated by this, we propose a copula-based multi-view clustering model where a copula enables the model to accommodate the directional dependence existing in the datasets.

Simultaneous 12-Lead Electrocardiogram Synthesis using a Single-Lead ECG Signal: Application to Handheld ECG Devices

no code implementations20 Nov 2018 Kahkashan Afrin, Parikshit Verma, Sanjay S. Srivatsa, Satish T. S. Bukkapatnam

This work is perhaps the first successful attempt to synthesize clinically equivalent synchronous 12-lead ECG from single-lead ECG.

Balanced Random Survival Forests for Extremely Unbalanced, Right Censored Data

no code implementations24 Mar 2018 Kahkashan Afrin, Gurudev Illangovan, Sanjay S. Srivatsa, Satish T. S. Bukkapatnam

Accuracies of survival models for life expectancy prediction as well as critical-care applications are significantly compromised due to the sparsity of samples and extreme imbalance between the survival (usually, the majority) and mortality class sizes.
