Pattern Information Processing
Our research interests include basic theories of pattern recognition and understanding, and applied fields of visual information processing, language information processing, and speech information processing. As research on Pattern Information Processing, we apply methods from neuroscience and artificial intelligence such as machine learning, statistics, artificial intelligence, and data mining to design appropriate feature representations and discriminative models for images, videos, texts, and speeches.

We are studying technologies for image understanding, recognition, and synthesis in the fields of computer vision, computational photography, and computer graphics. Specifically, to capture and utilize the rich information contained in light fields, we research and develop methodologies that combine cutting-edge cameras and lighting systems with mathematical models and machine learning.

As an application of natural language processing, automated essay scoring is conducted. Evaluating student essays can be labor-intensive for human graders with arising issues of consistency in evaluations. To address these issues, we have developed an automated essay scoring model and a supporting tool for the essay grading process. By utilizing machine learning techniques, the target of this research is to establish a more reliable and efficient approach for scoring essays. Since Japanese essay datasets have been limited, we have constructed and provided a dataset of scored Japanese essays to the research community.

Our goal is to develop technologies to enable advanced communication between humans and machines, such as spoken dialogue interfaces and action recognition from biological signals. To achieve this goal, we are researching methods that can represent and process multimodal-information sources based on speech processing, signal prcessing, and machine learning.
