Researcher

Graduate Student

The University of Tokyo

Outline

Mimicry is a fascinating phenomenon generated by natural selection and has attracted the interest of many people. However, measuring the perfection of mimicry is difficult. The conventional method is inevitably accompanied by arbitrary judgments of an observer and the assessment by real predators needs a costly experiment. In this project, I’m going to develop a novel deep neural network that imitates the visual system of birds and try to assess the quality of the mimetic trait of butterflies as an example. This project will contribute to our understanding about how can artificial intelligence imitate the reaction of the animal other than human.

Researcher
Ayumi Ohnishi

Assitant Professor
Faculty of Engineering

Outline

Sensory enhancement devices, such as eyeglasses and hearing aids, are essential for improving the quality of human life. There is a possibility that the human five senses are daily affected by fatigue. If a sensory enhancer does not consider fatigue, it causes serious problems. This research investigates the effects of physical and mental fatigue on the five senses. Based on these results, I implement the AI-based sensation enhancement system to overcome problems derived from exhausted five senses.

Diagnostic support AI system for myocardial ischemia by patient-by-patient basis blood flow information

Researcher
Masateru Kawakubo

Assistant Professor
Faculty of Medical Sciences

Outline

Impaired coronary blood flow causes myocardial ischemia. Optimal treatment of myocardial ischemia is based on the image diagnosis by experienced radiologist. Therefore, a lack of experienced radiologists leads to less confident treatment and can undermine the consensus and conviction of patients in clinical situations. In this research project, I am planning to build the AI that proposes additional diagnostic image information to the conventional myocardial imaging for ischemia. Also I will reveal that this diagnostic support AI will increase the confidence of diagnoses of ischemia in general radiologist and cardiologist. My goal in this project is to build a diagnostic support AI system which allows patients to be treated of myocardial ischemia with peace of mind.

Outline

This research project aims to design a fast and accurate method for estimating radio propagation using deep learning and image sensor based crowdsensing. The communication efficiency of wireless communications is limited by radio propagation estimation accuracy. The research motivation is in the fact that radio propagation characteristics strongly depend on structure information. To break through the performance limitations of the conventional received signal power based crowdsensing, this project establishes a method for obtaining and using structure information specialized for estimating radio propagation from video and images. The biggest deliverable obtained through this project will be a data analysis infrastructure that can meet the growing demand for wireless communications over the next generation.

Integration of rule-based methods with machine learning in computer-aided music composition

Researcher
Tsubasa Tanaka

Part-time Lecturer
Faculty of Music
Tokyo University of the Arts

Outline

In the field of computer-aided music composition, how to reflect composer’s intention, give originality to the generated pieces, and guarantee the pieces’ quality are important issues. To deal with these problems, composers tend to prefer rule-based approaches based on objective functions or constraints of their own design rather than machine-learning-based methods. With this in mind, this project aims at integrating rule-based approaches with machine learning to utilize the power of machine learning in composition systems.

Researcher
Chia-Ming Chang

Project Lecturer
Graduate School of Information Science and Technology
The University of Tokyo

Outline

There is a huge demand for better machine learning results. One popular approach is to design good algorithms which many studies focus on. However, there is also another approach which is to “provide better data”. This study focuses on how to provide better data (without increasing costs) for improving machine learning results. This study aims (a) to bring “design thinking” into machine learning, (b) to improve machine learning results by providing better data, and (c) to design new annotation interfaces that allows non-expert annotators to complete a labeling task more quickly, more correctly, and support self-learning during annotation.

Mingbo Cai

Learning categories grounded in sensation without supervision

Researcher
Mingbo Cai

Assistant Professor
Institutes for Advanced Study
The University of Tokyo

Outline

In most current deep learning works, categories are learned by supervised learning, and the resulting neural networks learn to categorize images instead of objects. To overcome this, this project will develop new neural network architecture and learning objective to force neural networks to emerge categorical representations of objects by learning to predict their future states without relying on human supervision. It takes inspiration from how infants and animals form initial concepts of categories by themselves.

In this study, computational models of emotional responses are developed. More specifically, emotional responses are measured under two different conditions of visual and auditory stimuli, and computational models of emotional responses that take individual differences into account are examined. Although there are various definitions of emotional responses, this study refers to them as the physical responses such as visceral activities that occur in response to stimuli. This project aims to elucidate basic mechanisms behind emotions and to open up a path toward building robots with emotions by computationally modeling the emotional responses, which are the base of emotions.

Takashi Morita

Exploring deep transfer learning across heterogeneous data

Researcher
Takashi Morita

Designated Senior Assistant Professor
Academy of Emerging Sciences
Chubu University

Outline

Today’s artificial intelligence (AI) is built on big data. When the primary data for AI training is not available on a large scale, a method called transfer learning is used; AI is first pretrained on other big data that look similar to the main data, and then, a part of the pretrained AI is fine-tuned for the main data. However, even such “similar” big data are often unavailable. To tackle this problem, this research project extends transfer learning to pairs of heterogeneous data, which do not look alike on surface, and explores its effectiveness. Heterogeneous transfer learning also provides a novel similarity metric between data whose comparison is of particular academic interest (e.g., human language vs. animal vocalization).

Outline

Electron beams have been widely used in both science and industry. Even though the spatial shape of electron beams can be precisely controlled, it is still challenging to control the temporal structure with high precision. In this research, we aim at developing a technology for producing electron beams having tailored temporal profiles with the aid of machine learning (AI). This research will open up novel opportunities for ultrafast imaging of chemical reactions, quantum information, damage-reduced electron microscopy and particle accelerators.
