Abstract: An interface receives time series data including multiple observed values of an observed parameter that are acquired at different time points for obtaining physiological information of a subject. A processor inputs the time series data into a prediction model to output, as a prediction result, a range within which values interpolating the multiple observed values may fall. The processor generates at least one first interpolated value by interpolating the multiple observed values with a first method. The processor generates at least one second interpolated value by interpolating the multiple observed values with a second method that is different from the first method. The processor identifies, as the prediction result, a range defined between a maximum value and a minimum value among the first interpolated value and the second interpolated value.

Abstract: An interface receives time series data including multiple observed values of an observed parameter that are acquired at different time points for obtaining physiological information of a subject. A processor inputs the time series data into a prediction model to perform prediction of one or more unobserved values of the observed parameter. The processor causes an output device to visualize a range within which the one or more unobserved values may fall. The range is changed in accordance with a time interval between the different time points.

Abstract: Training data is used in machine learning of a prediction model adapted to predict physiological information. An original data set includes a first observed value of an observed parameter for obtaining the physiological information acquired from a living body at a first time point, and a second observed value of the observed parameter acquired from the living body at a second time point different from the first time point. A first interpolation data set is generated by interpolating, with a first method, at least one value of the observed parameter in a time period between the first time point and the second time point. A second interpolation data set is generated by interpolating, with a second method different from the first method, at least one value of the observed parameter in the time period. The training data is generated so as to include the first and second interpolation data sets.

Abstract: A gas laser amplifier includes a housing, discharge electrode pairs, and an optical resonator. The housing includes an entrance window that allows entry of a first laser beam from outside and an exit window that allows exit of the first laser beam amplified. Each of the discharge electrode pairs excites a laser gas supplied between discharge electrodes facing each other in the housing. The optical resonator causes a second laser beam to oscillate with a gain of the excited laser gas in a non-incident state where the first laser beam from outside the housing does not enter the housing through the entrance window. In an incident state where the first laser beam enters the housing through the entrance window, the optical resonator suspends the oscillation of the second laser beam.
