Nonuniform Negative Sampling and Log Odds Correction with Rare Events Data
HaiYing Wang, Aonan Zhang, Chong Wang
We investigate the issue of parameter estimation with nonuniform negative sampling for imbalanced data. We first prove that, with imbalanced data, the available information about u…
Efficient state and parameter estimation for high-dimensional nonlinear system identification with application to MEG brain network modeling
Matthew F. Singh, Chong Wang, Michael W. Cole +1
System identification poses a significant bottleneck to characterizing and controlling complex systems. This challenge is greatest when both the system states and parameters are no…
Fully Supervised Speaker Diarization
Aonan Zhang, Quan Wang, Zhenyao Zhu +2
In this paper, we propose a fully supervised speaker diarization approach, named unbounded interleaved-state recurrent neural networks (UIS-RNN). Given extracted speaker-discrimina…
TopicRNN: A Recurrent Neural Network with Long-Range Semantic Dependency
Adji B. Dieng, Chong Wang, Jianfeng Gao +1
In this paper, we propose TopicRNN, a recurrent neural network (RNN)-based language model designed to directly capture the global semantic meaning relating words in a document via…
Scalable Modeling of Conversational-role based Self-presentation Characteristics in Large Online Forums
Abhimanu Kumar, Shriphani Palakodety, Chong Wang +3
Online discussion forums are complex webs of overlapping subcommunities (macrolevel structure, across threads) in which users enact different roles depending on which subcommunity…
Embarrassingly Parallel Variational Inference in Nonconjugate Models
Willie Neiswanger, Chong Wang, Eric Xing
We develop a parallel variational inference (VI) procedure for use in data-distributed settings, where each machine only has access to a subset of data and runs VI independently, w…
