Decomposition Bounds for Marginal MAP
Wei Ping, Qiang Liu, Alexander Ihler
Marginal MAP inference involves making MAP predictions in systems defined with latent variables or missing information. It is significantly more difficult than pure marginalization…
Regularized Minimax Conditional Entropy for Crowdsourcing
Dengyong Zhou, Qiang Liu, John C. Platt +2
There is a rapidly increasing interest in crowdsourcing for data labeling. By crowdsourcing, a large number of labels can be often quickly gathered at low cost. However, the labels…
Communication-efficient sparse regression: a one-shot approach
Jason D. Lee, Yuekai Sun, Qiang Liu +1
We devise a one-shot approach to distributed sparse regression in the high-dimensional setting. The key idea is to average "debiased" or "desparsified" lasso estimators. We show th…
Cheaper and Better: Selecting Good Workers for Crowdsourcing
Hongwei Li, Qiang Liu
Crowdsourcing provides a popular paradigm for data collection at scale. We study the problem of selecting subsets of workers from a given worker pool to maximize the accuracy under…
