Title:
Image Processing Using Machine Learning for Human Perception

Speaker:
Prof. Kaoru Arakawa (Meiji University)

Schedule:
8:30-10:00, 28 November 2018

Abstract:
Since images are nonstationary and are to be evaluated by human perception, conventional linear signal processing is not valid for them. In order to get satisfactory results in image processing, introduction of machine learning is expected, because it can consider nonstationary fine structures in images and realize human-like smart data processing. In this talk, methods for image processing using machine learning, which consider human perception, are presented. Here, two types of machine learning are considered; one is to use training data and the other is not. The former is represented by neural networks which are based on minimum mean square error criteria for desired output, and the latter is interactive evolutionary computing based on human subjective criteria. The performance is shown not only in general image processing such as denoising and enhancement, but also in special usage such as facial photo retouching.

Title:
Non-orthogonal Access Schemes in 5G – Room Between Channel Capacity and System Throughput

Speaker:
Prof. Yukitoshi Sanada (Keio University)

Schedule:
8:30-10:00, 29 November 2018

Abstract:
Because of the wide use of smart phones and mobile terminals, a higher data rate is an inevitable demand in wireless communications. The 5th generation (5G) mobile communication systems, which are expected in 2020, have been investigated to accommodate explosive traffic growth. In the 5G, new multiple access schemes such as massive MIMO, NOMA, or SCMA has been proposed and actively investigated. The notable point of these schemes is that non-orthogonality is effectively utilized. To realize these multiple access schemes, efficient and near-optimum multi-signal detection techniques have been developed from the CDMA. This keynote overviews those multiple access schemes and focuses on multi-signal detection techniques that are closely related to multiple access schemes.
