Claim 0:
1. A method of detecting an abnormality in time series data, the method being performed in a computing device including one or more processors and a memory storing one or more programs executed by the one or more processors, the method comprising:
first masking to cover a portion of input time series data with a mask;
generating first-restored time series data in which the time series data is restored by inputting the first-masked time series data to a generator;
calculating a difference between the first-restored time series data and original time series data;
second masking to cover a portion of the time series data with a mask on basis of the calculated difference; and
generating second-restored time series data in which the time series data is restored by inputting the second-masked time series data to the generator.
