Researcher
Keisuke Okumura

Researcher
Artificial Intelligence Research Center (AIRC)
National Institute of Advanced Industrial Science and Technology (AIST)

Outline

This project studies the optimization of environments for multi-agent path planning, wherein the environments are designed by obstacle layouts or installing one-way roads, to name just a few. By automating environmental design that conventionally has been manually adjusted, the project aims at providing efficient and safe environments for multi-robot coordination. Doing so is expected to be beneficial for several important domains including factory automation. Developed methodologies will be tested by both simulation and real-robot demonstrations as proof of concept.

Ryusei Oketani

Chirality recognition of molecular crystals by deep learning

Researcher
Ryusei Oketani

Assistant professor
Graduate School of Engineering Science
Osaka University

Outline

This project aims to develop a deep learning model enabling chirality recognition of chiral single crystals from microscopic images for facile and rapid measurement of enantiomeric excess in solid state. The chirality of crystalline solids has been characterized by either spectroscopic method or X-ray diffraction measurement so far. However, these techniques need a time-consuming data collection to obtain information on anisotropy or atomic coordinates in crystals. Toward a facile and rapid measurement of chirality of crystals, a deep learning model in end-to-end fashion, i.e., from crystal detection to chirality recognition, will be constructed. This work would contribute as a novel enantiomeric excess measurement of crystalline materials.

Mizuka Komatsu

Modeling Auditory Attention: Coordinating a Dynamic Causal Model and Deep Learning

Researcher
Mizuka Komatsu

Assistant Professor
Graduate School of System Informatics
Kobe University

Outline

The ability to select and focus on a part of sound from the outside world is called auditory attention. Existing models of auditory attention can be divided into two broad categories: the bottom-up approach, which focuses on the sound itself; and the top-down approach, which focuses on listening tasks. However, advances in data measurement technology hold the promise of more advanced modeling methods capable of integrating both types of models. This study pursues this possibility by coordinating mathematical and information sciences and their technologies, such as dynamic causal modeling and deep learning.

Quantitative Understanding of Knowledge Gap in Research Toward Paper Recommendation

Researcher
Takahiro Miura

Research Fellow
Center for Computational Social Science
Kobe University

Outline

This project aims to build a model to identify knowledge gap areas in research by focusing on delayed recognition in science. In general, cutting-edge research appears from the surroundings of popular fields, known as the ‘bandwagon effect.’ Empirically, the knowledge gap functions complementarily, causing disconnection and discord in science to enhance the non-linear growth of research fields, but the general application for researchers utilizing the knowledge gap is still in its infancy. To overcome this, this project will develop the model to recommend papers falling into the knowledge gap for the input papers, with the goal of implementing the application to stimulate researchers’ emerging knowledge creation.

Outline

The construction of AI system to automatically differentiate blood cells in peripheral blood and bone marrows is an important task, but it involves difficulties in accurately annotating a wide variety of morphologies and collecting data in diverse imaging environments. This project aims to develop an AI method that can recognize unknown condition of cells and build a technology that enables screening without assuming detailed classification by human hands. We will also develop interpretability techniques for effective analysis and methods that are robust to environmental changes.
