Time-series signal prediction device, radiation treatment device, time-series signal prediction method, and storage medium

A time-series signal prediction method that is performed by a computer, the time-series signal prediction method comprising:

• acquiring a time-series signal associated with a patient's biological information;
• dividing the time-series signal into sub signals at predetermined intervals and converting the sub signals to block signals of a time series which is shorter than a time series of the time-series signal;
• acquiring, from the block signals, a feature vector indicating a time-series signal at a time subsequent to the time at which the time-series signal has been acquired;
• and
• converting the feature vector to a prediction signal associated with the patient's biological information.

A non-transitory computer-readable storage medium storing a program causing a computer to perform:

• acquiring a time-series signal associated with a patient's biological information;
• dividing the time-series signal into sub signals at predetermined intervals and converting the sub signals to block signals of a time series which is shorter than a time series of the time-series signal;
• acquiring, from the block signals, a feature vector indicating a time-series signal at a time subsequent to the time at which the time-series signal has been acquired;
• and
• converting the feature vector to a prediction signal associated with the patient's biological information.
