Patent number: 11263172Abstract: A method, computer program product, and/or computer system improves a future efficiency of a specific system. One or more processors receive multiple historical data snapshots that describe past operational states of a specific system. The processor(s) identify a time series pattern for the time series of data in the multiple historical snapshots and calculate their variability. The processor(s) then determine that the variability in a first sub-set of the time series pattern is larger than a predefined value, and determine that future values of the first set of the time series pattern are a set of non-forecastable future values. The processor(s) also determine that the variability in a second sub-set of the time series pattern for the data is smaller than the predefined value, and utilizes this second sub-set to modify the specific system at a current time.Type: GrantFiled: January 4, 2021Date of Patent: March 1, 2022Assignee: International Business Machines CorporationInventors: Yuan-Chi Chang, Venkata Nagaraju Pavuluri, Dharmashankar Subramanian, Long Vu, Debarun Bhattacharjya, Timothy Rea Dinger
