Abstract: An image generation device includes an imaging unit configured to convert data representing an expression level for each microRNA type into image-rendition data serving as data representing a matrix of two dimensions or more, a classification unit configured to perform classification of the image-rendition data, and a contribution-presentation-image generation unit configured to generate a contribution-presentation image representing a contribution of a specific part of the image-rendition data to the classification.

Abstract: A driver assistance device to assist in giving a more appropriate stimulus to a driver is obtained. The driver assistance device includes an acquisition unit to acquire temporal change information indicating a change of a driver's arousal state over time, and a stimulus determination unit to determine a stronger stimulus as a stimulus to be given to the driver as an absolute value of the change over time indicated by the temporal change information acquired by the acquisition unit is larger.

Abstract: In a personal authentication system based on seat pressure, a registration apparatus adjusts parameters by means of feature computation using, as training data, a time series pressure distribution data piece of a would-be registrant and time series pressure distribution data pieces of a plurality of other persons, and back propagation based on a difference between the results of the feature computation and training signals, and stores the adjusted parameters as a personal identification data piece. The authentication apparatus determines the personal identification value by means of computation on a time series pressure distribution data piece of an authentication object person, using, as parameters, a personal identification data piece for each registered person, and performs authentication. The feature computation includes computations for extracting a physical feature and a behavioral feature.
