Abstract
One embodiment of the present invention provides an apparatus and the like for improving the accuracy of deterioration estimation regarding a monitoring target. An information processing apparatus as one embodiment of the present invention includes a detector, a separator, a calculator, and an estimator. The detector detects a normal waveform pattern included in a waveform of time-series data of a target. The separator separates the waveform of the time-series data into components while removing the normal waveform pattern that is detected. The calculator calculates a feature of the time-series data based on at least one of the components. The estimator estimates deterioration of the target based on the feature.

An information processing apparatus comprising:
- processing circuitry configured to:
- detect a predetermined normal waveform pattern included in from a first waveform of time-series data acquired by a sensor on a monitoring target;
- remove the predetermined normal waveform pattern from the first waveform of time-series data to obtain a second waveform of time-series data and separate the second waveform of the time-series data into a trend component that indicates an increasing or decreasing trend of the first waveform, a seasonal component that repeats in a certain cycle depending on time, and a remainder component remaining after the trend component and the seasonal component are removed from the first waveform of time series data;
- calculate a feature of the time-series data based on at least one of the trend component, the seasonal component, or the remainder component;
- and
- estimate a deterioration state of the monitoring target based on the feature.
