Abstract

In this talk we present a new direction of multi-task multi-view learning where we have data sets with multiple tasks, multiple views and multiple labels. We call this problem a multi-task multi-view multi-label learning problem or MTVL learning for short. There is a wide application of MTVL leaning where examples include Internet of Things, brain science, and text categorization. In designing effective MTVL learning algorithms, we hypothesize that a key component is to ˇ°disentangleˇ± interactions among tasks, views, and labels, or performing factor analysis to better understand task-view-label interactions. For that purpose, we have developed an adaptive-basis multi-linear analyzers that utilizes a tensor loading factor to modulate interactions among multiple latent factors. We designed a new MTVL learning algorithm, aptMTVL, and evaluated its performance on several real-world data sets. The experimental results demonstrated the effectiveness of our proposed method as compared to state-of-the-art MTVL learning algorithms.
