Title: AI-based Smart Healthcare

Prof. Tomoaki Ohtsuki

Keio University, Japan


With the rapid aging society in developed countries particularly Japan, social costs for nursing care and medical expenses are also rising. Meanwhile, the size of the average family has continued to shrink, which results in the increase of elderly people living alone. Smart healthcare is expected to support the aging society where people can live healthily and peacefully while reducing the costs for support dramatically. To realize such a society, smart technologies are necessary. Now AI is becoming more and more important in smart healthcare as well. In this talk, we will introduce AI-based smart healthcare. We will also introduce some techniques to detect mental diseases.

Title: Transition To Digital Power Grids Education

Assoc. Prof. Wijarn Wangdee

Senior researcher at the Center of Excellence in Electrical Power Technology (CEPT), Thailand


Electrical power grids around the world are dramatically evolving under the power and energy sector transformation. Decabonization goal to neutralize CO2 emission has promoted a full utilization of green and renewable energy technologies as well as transportation electrification in the near future. This subsequently leads to the decentralization of a large number of small renewable energy sources, known as distributed energy resources (DERs), which can play a key role in the future power grids where a coordination among these DERs will be enabled by emerging digital technologies. With all advancements in the technologies come together, it creates a new paradigm known as a ‘prosumer’ where a consumer of electricity (load demand) can also turn into a producer of electricity (power generation), for instance, selling the electricity from a residential rooftop solar power at daytime while buying the electricity from power utility at nighttime. This new power industry paradigm shift may be referred to as demand-side disruption. To enable a smooth transition to the digital power grid paradigm, a frontier of a traditional power engineering education must be expanded to overlap and connect with communication technology as well as information technology (i.e. ICT) in order to complement or fulfil the future power grid complexity. This education augmentation will prove important for the next generation of power engineers in making decisions on very sophisticated power grid control, operation and coordination that greatly rely on the utilization of big data flowing back and forth among the large numbers of relevant power grid players through an energy internet.

Title: Toward Research Transformation for Sustainable Data-centric Society

Prof. Takao Onoye

Osaka University, Japan


As we all are confronted with global scale issues such as climate change, environmental disaster, world hunger, pandemic, etc., universities are requested to contribute for solving these issues. Researches at the universities should be transformed to aim to create a better and fairer world. In this talk, several activities are introduced by using advanced digital technology for achieving sustainable development goals (SDGs). A key factor for success is organizing transdisciplinary research units by bridging digital/data scholars and those of other disciplines in the domains of life science, biomedical science, science and engineering, and humanities.

This research is focused on the development of autonomous orchard spray rover which is mainly targeting to durian orchard. The current developing status will be updated. The procedure for creating spraying trajectory will be mainly precented. Depth camara is used to grab all information in an orchard. Then the semantic segmentation is used to distinguish durian canopy from an environment. Moving obstacles are not considered. the segmented canopy is fused with depth information to estimate durian canopy with an ellipsoid surface. Finally, the trajectory is created on such surface.

Title: Psychoacoustic Processing in DNN-HMM based Speech Recognition

Yoshikazu Miyanaga

Chitose Institute of Science and Technology, Chitose, Japan

University of Technology Sydney, Sydney, Australia King Mongkut’s University of Technology Thonburi, Bangkok, Thailand


This topic introduces the design of a noise robust automatic speech recognition (ASR) system. It is suitable for speech communication robots.  For almost all of speech communication robots, a strong noisy robust speech recognition has been demanded. For both of a continuous speech dialog-based and a command-based ASR, we have designed strong robust ASR systems against various noise circumstances. The psychoacoustic masking effect for speech feature extraction in ASR is introduced in this presentation. It is based on the human auditory system. Generally, the mel-frequency cepstral coefficients (MFCC) are widely used speech features in ASR systems, and however one of their main drawbacks is the lack of psychoacoustic processing, which can affect and hamper the results. This presentation introduces noise robust speech features which improve upon MFCC and its modified features. A psychoacoustic model-based feature extraction which simulates the perception of sound in the human auditory system is investigated and integrated into the front-end technique of the proposed ASR system. The proposed new speech features are called as gammatone filter bank cepstral coefficients with psychoacoustic masking processing (PGFCC). They are applied into conventional GMM-HMM and DNN-HMM. The DNN-HMM with PGFCC shows the highest accuracy in these experiments on ASR. This new approach would be useful for noise robust speech recognition embedded into robots.

Title: Terahertz communication systems for future access networks

Tetsuya Kawanishi

Waseda University, Japan


We provide overviews on radio links using terahertz waves which can provide high-speed wireless transmission. However, transmission distances would be shorter than a few kilometers due to attenuation in the air. Thus, we should rely on seamless networks consisting of terahertz radio-links and optical fibers.
