Time series data represents sequences that change randomly over time, where forecasting involves using historical data points to predict current and future values. Traditional time series prediction methods in stochastic process theory typically employ linear models such as AR, MA, and ARMA models. However, these models require manual selection of model types and determination of orders, often resulting in significant prediction errors. Wavelet theory, an emerging mathematical method, has gained prominence in recent years. Wavelet neural networks combine wavelet analysis with neural networks to effectively address time series prediction challenges. This case study demonstrates the application of wavelet neural networks for traffic flow prediction, highlighting their effectiveness in time series forecasting through practical implementation and algorithm validation.

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.
