| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | It has attracted considerable attention to use crowdsourcing services to collect a large amount of labeled data for machine learning, since crowdsourcing services allow one to ask the general public to label data at very low cost through the Internet. The use of crowdsourcing has introduced a new challenge in machine learning, that is, coping with low quality of crowd-generated data. There have been many recent attempts to address the quality problem of multiple labelers, however, there is a serious drawback in the existing approaches, that is non-convexity of the objective function. Most of the existing methods consider true labels as latent variables, which results in non-convex optimization problems. In this paper, we propose a convex optimization formulation of learning from crowds by introducing personal models of individual crowds without estimating true labels. We also devise an efficient iterative method for solving the convex optimization problem by exploiting conditional independence structures in multiple classifiers. |
