Time series refers to a sequence of data points arranged at specific time intervals, representing various metrics such as product demand, production volume, or sales figures. The intervals can be measured in any time unit (hours, days, weeks, months). When establishing relationships with dependent variables proves difficult or data collection is challenging, regression analysis may not be suitable. For cases where high prediction accuracy isn't critical, time series analysis offers an effective alternative. Implementation typically involves preprocessing data using wavelet decomposition (e.g., MATLAB's wavedec function) to extract features, followed by neural network training with functions like feedforwardnet for pattern recognition and forecasting.
