Variational Latent-State GPT for Semi-supervised Task-Oriented Dialog Systems

no code implementations9 Sep 2021 Hong Liu, Yucheng Cai, Zhenru Lin, Zhijian Ou, Yi Huang, Junlan Feng

In this paper, we propose Variational Latent-State GPT model (VLS-GPT), which is the first to combine the strengths of the two approaches.

Metal-Insulator Transition in $n$-type bulk crystals and films of strongly compensated SrTiO$_3$

Wasserstein Soft Label Propagation on Hypergraphs: Algorithm and Generalization Error Bounds

no code implementations6 Sep 2018 Tingran Gao, Shahab Asoodeh, Yi Huang, James Evans

Inspired by recent interests of developing machine learning and data mining algorithms on hypergraphs, we investigate in this paper the semi-supervised learning algorithm of propagating "soft labels" (e. g. probability distributions, class membership scores) over hypergraphs, by means of optimal transportation.

Towards a New Science of a Clinical Data Intelligence

no code implementations17 Nov 2013 Volker Tresp, Sonja Zillner, Maria J. Costa, Yi Huang, Alexander Cavallaro, Peter A. Fasching, Andre Reis, Martin Sedlmayr, Thomas Ganslandt, Klemens Budde, Carl Hinrichs, Danilo Schmidt, Philipp Daumke, Daniel Sonntag, Thomas Wittenberg, Patricia G. Oppelt, Denis Krompass

We argue that a science of a Clinical Data Intelligence is sensible in the context of a Big Data analysis, i. e., with data from many patients and with complete patient information.
