Pollux: Co-adaptive Cluster Scheduling for Goodput-Optimized Deep Learning

2 code implementations27 Aug 2020 Aurick Qiao, Sang Keun Choe, Suhas Jayaram Subramanya, Willie Neiswanger, Qirong Ho, Hao Zhang, Gregory R. Ganger, Eric P. Xing

Some recent schedulers choose job resources for users, but do so without awareness of how DL training can be re-optimized to better utilize the provided resources.

Online Kernel based Generative Adversarial Networks

no code implementations19 Jun 2020 Yeojoon Youn, Neil Thistlethwaite, Sang Keun Choe, Jacob Abernethy

We propose a novel approach that resolves many of these issues by relying on a kernel-based non-parametric discriminator that is highly amenable to online training---we call this the Online Kernel-based Generative Adversarial Networks (OKGAN).

On Leveraging the Visual Modality for Neural Machine Translation

no code implementations WS 2019 Vikas Raunak, Sang Keun Choe, Quanyang Lu, Yi Xu, Florian Metze

Leveraging the visual modality effectively for Neural Machine Translation (NMT) remains an open problem in computational linguistics.

Audio Cover Song Identification using Convolutional Neural Network

no code implementations1 Dec 2017 Sungkyun Chang, Juheon Lee, Sang Keun Choe, Kyogu Lee

To do this, we first build the CNN using as an input a cross-similarity matrix generated from a pair of songs.
