An End-to-End Time Series Model for Simultaneous Imputation and Forecast

no code implementations1 Jun 2023 Trang H. Tran, Lam M. Nguyen, Kyongmin Yeo, Nam Nguyen, Dzung Phan, Roman Vaculin, Jayant Kalagnanam

Time series forecasting using historical data has been an interesting and challenging topic, especially when the data is corrupted by missing values.

Interpretable Clustering via Multi-Polytope Machines

no code implementations10 Dec 2021 Connor Lawless, Jayant Kalagnanam, Lam M. Nguyen, Dzung Phan, Chandra Reddy

To solve our formulation we propose a two phase approach where we first initialize clusters and polytopes using alternating minimization, and then use coordinate descent to boost clustering performance.

A Scale Invariant Flatness Measure for Deep Network Minima

no code implementations6 Feb 2019 Akshay Rangamani, Nam H. Nguyen, Abhishek Kumar, Dzung Phan, Sang H. Chin, Trac. D. Tran

It has been empirically observed that the flatness of minima obtained from training deep networks seems to correlate with better generalization.
