Multi-view Anomaly Detection via Probabilistic Latent Variable Models
Tomoharu Iwata, Makoto Yamada
We propose a nonparametric Bayesian probabilistic latent variable model for multi-view anomaly detection, which is the task of finding instances that have inconsistent views. With…
Collaboration on Social Media: Analyzing Successful Projects on Social Coding
Yuya Yoshikawa, Tomoharu Iwata, Hiroshi Sawada
Social Coding Sites (SCSs) are social media services for sharing software development projects on the Web, and many open source projects are currently being developed on SCSs. One…
