  • Title
    Automatic Estimation of Affective Impressions from a Single Sound-symbolic Word and Word-based Visualization of Perceptual Space
  • Abstract
    The semantic differential (SD) was mainly developed by the US psychologist Charles E. Osgood in 1950s. Since then, it has been widely applied to capture the affective and cognitive factors of respondents’ attributions to selected concepts and objects on a multidimensional level. This method asks respondents to analyze their affective impression and perceptual experiences one by one. On the other hand, Gestalt psychology implies that human understands external stimuli as whole rather than the sum of their parts. Therefore, we proposed a system that can automatically estimate multidimensional ratings of affective impressions of objects from a single sound-symbolic word that has been spontaneously and intuitively expressed by a user. When a user inputs a sound-symbolic word into the system, the system refers to a database of phonemes and their auditory impressions and calculates ratings in terms of fundamental scales of affective and perceptual experiences. In this talk I will outline the advantage of our method in visualizing our affective impressions of objects and our perceptual space.

  • Title
    Current Achievements and Future Perspectives for Artificial Intelligence in Medical Engineering
  • Abstract
    There is no doubt that artificial intelligence (AI) will play the important role of the future medical science. The Ministry of Health, Labor and Welfare (MHLW) in Japan indicates six important areas for AI development in medicine; they are genomic medicine, diagnostic imaging support, diagnostic treatment support, drug development, nursing care, and surgery assistance. And, AI based computer programs for diagnosing diseases have been approved recently by Pharmaceuticals and Medical Devices Agency (PMDA), JAPAN. At first, this talk will survey the current progress of AI development of medicine in not only Japan but also world.
    Next, I will introduce a basic methodology of applying AI to medicine through our achievements on computer-aided diagnosis of rheumatoid arthritis (RA). RA is an autoimmune disorder and results in painful joints. The guideline of RA diagnosis method includes the evaluation of hand X-ray radiograph. The RA progress in X-ray radiograph can be quantified by using modified total sharp score (mTSS), which is defined as the sum of erosion and joint space narrowing (JSN) scores. Due to the time consuming of for image interpretation, many hospitals skips the numeric evaluation of X-ray radiograph. The proposed system first automatically detects finger joints in X-ray radiograph images using support vector machine (SVM), convolutional neural network (CNN), and needless to say image processing techniques. The system belongs to the key area of diagnostic imaging support. The accurate quantification of RA will assist physicians to perform the appropriate treatment, and then will support the evidence based medicine (EBM).
    In conclusion, I will summarize the talk, and mention the future perspectives.
