Abstract(in English) | This paper proposes an extension of principal component analysis for gaussian process posteriors which is denoted by GP-PCA. GP-PCA can be applied to multi-task learning, meta-learning and transfer learning. The issue is how to define an structure of a set of GP posteriors such as a coordinate system and a distance. In this study, we define infinite dimensional structure reduced to finite dimensional structure based on information geometry. Especially, we show that a set of GP posteriors becomes a finite dimensional dually flat. Moreover, we demonstrate the effectiveness of GP-PCA through experiments. |
