SYSTEM, METHOD AND COMPUTER PROGRAM FOR FORECASTING A TREND OF A NUMERICAL VALUE OVER A TIME INTERVAL

摘要

Examples relate to a system, to a method and to a computer program for forecasting a trend of a numerical value over a time interval. The system comprises processing circuitry configured to determine an estimate of the numerical value for the time interval by training a first machine-learning model based on historical data on the numerical value. The processing circuitry is configured to divide the time interval into a first and a second sub-interval. The processing circuitry is configured to determine an estimate of the numerical value for the first sub-interval by training a second machine-learning model based on the historical data on the numerical value. The processing circuitry is configured to determine an estimate of the numerical value for the second sub-interval based on the estimate of the numerical value for the time interval and based on the estimate of the numerical value for the first sub-interval.
