Abstract:
A method for generating a workflow includes: generating multiple candidate workflows by making a modification to part of an existing workflow that defines multiple condition branches and following contents at respective destinations of the condition branches; obtaining KPI fluctuation vectors one for each candidate workflow from the existing workflow; generating multiple synthesized policies by synthesizing two or more of the KPI fluctuation vectors; calculating, when one of selected routes of multiple candidate workflows contains the modifications, a KPI predicted value of each synthesized policy by reflecting a weight parameter on the KPI fluctuation vector, the weight parameter being set such that a weight for a modification to an upper point of the selected route is higher than that to a lower point of the selected route among the modifications; and outputting a workflow of one of the synthesized policies the KPI predicted value of which satisfies a target value.

A meal intake detection device includes: a memory; and a processor coupled to the memory and configured to: detect a rise of heart rate; extract as a meal intake candidate a time range from a detected rise to time when the heart rate decreases to a predetermined value in temporal changes in heart rate, and when a second meal intake candidate is extracted in a time range of an extracted first meal intake candidate, separate the first meal intake candidate and the second meal intake candidate along a predetermined line; and detect whether each of the first meal intake candidate and the second meal intake candidate is a meal intake based on feature quantities relating to the first meal intake candidate and the second meal intake candidate that are separated.
Abstract:
A pulse wave detection device acquires an image. The pulse wave detection device extracts a living body region included in the image. The pulse wave detection device generates a signal from time series data of a pixel value included in a partial image of the image corresponding to the living body region. The pulse wave detection device calculates a variation index for evaluating a degree of disturbance of a pulse wave included in the signal. The pulse wave detection device controls whether to output the signal by using the variation index.

Abstract:
A pulse wave detection apparatus detects a signal, and calculates a correlation coefficient between waveforms of the signal included in a first window and a second window having a predetermined duration, the correlation coefficient being smaller when a difference between dispersion of the amplitude value in the first window and dispersion of the amplitude value in the second window becomes larger.
