Electrical and
Information Engineering

Electrical and information engineering is an academic discipline that studies the nature, structures and logic of information from the points of generation, transmission, conversion, recognition and usage. This discipline also studies the theory and practice of information equipment and the hardware and software of information systems, with a focus on computers. This technology is indispensable and is a foundation of industry and life in our modern society. Electrical and information engineering is based on electrical and electronic engineering, communication engineering and computer science. The combination of these broad technological fields led to the creation of this advanced technological field of study.
Through instruction and research into electrical and information engineering, whith an eye towards taking consideration into the impact of information communication technology on society, the Faculty of Electrical and Information Engineering cultivates specialists who will acquire the ability to adapt to a wide range of electrical, information and communication related problems, and can therefore respond to modern day demands. Additionally, we work to cultivate specialists who can solve yet unknown problems autonomously and creatively.

“Compressed sensing”, used to restore the a whole from its various parts.

“Compressed sensing” is a technology that allows one to restore the entire multi-dimensional data (like image data) from randomly selected small parts of data. Although this method is relatively a new mathematical tool developed around 2006, it is closely related to the fundamental mathematical problem well-known as simultaneous linear equations. By using "compressed sensing" it is possible to obtain high-resolution MRI images from low-resolution images obtained in medical sites with short scan times.
Viewers can enjoy clear images even when only a small amount of image data is delivered over the Internet. In order to understand exactly how much information is required for restoration, knowledge of mathematics learned at university is necessary. However, the information can be restored from the least amount of data intuitively if it is represented as a “sparse vector”, (a vector with most components set to 0).
Although this method has been applied to the restoration of various signals including images, movies, and voice, in our laboratory we extend our research on the application of compressed sensing focusing regarding the sparseness of signals in communication systems and big data.

From Information Systems to Marketing.

With the development of AI and IoT, terminals are placed everywhere, and huge amounts of information are exchanged. Preventing congestion or delay of this information exchange is a task for future communication researchers. Currently, if there are 100 terminals, they must transmit signals one by one in order. When multiple terminals transmit signals at the same time, the signals collide and cannot be properly received. However, if we apply the compressed sensing approach, we can restore the complete transmitted signals of all terminals, with the number of transmissions less than the number of terminals, by making multiple conflicted signal transmissions by these 100 terminals at the same time and catching the received signals. As a result, we can receive signals from a large number of IoT terminals in a significantly shortened time.
If we apply it to big data, we can imagine for example that information regarding “payment status of utility bills in the past” is useful to know the “repayment tendency of mortgage loans”, but the information on “favorite food” could also be helpful. Compressed sensing can also be applied to find hidden relationships that humans have thus far not realized.
From signal processing to big data, we are researching and developing practical application of technologies that makes the world happy. If you are interested in both basic theory and application, please knock at the door of our laboratory.
