Topic modeling has been widely applied in a variety of industrial applications. Training high-quality model usually requires massive amount in-domain data, order to provide comprehensive co-occurrence information for the learn. However, data such as medical or financial records are often proprietary sensitive, which precludes uploading centers. Hence training topic models scenarios using conventional approaches faces dilemma: party (i.e., company institute) either tolerate scarcity sacrifice...
