Description: Time series normalization is the process of adjusting time series data to remove trends and seasonality, allowing for more effective and accurate analysis. This process is fundamental in data preprocessing, as it helps transform the data into a format that facilitates the identification of underlying patterns and forecasting. By eliminating unwanted components, such as long-term trends or seasonal fluctuations, analysts can focus on variations that are more relevant to the analysis. Normalization can include techniques such as time series decomposition, where data is separated into trend, seasonality, and noise components, or the use of statistical methods like differencing. This approach is particularly useful in various fields, including finance, meteorology, and engineering, where data often exhibits complex patterns. Normalization not only improves the quality of the analysis but also optimizes the performance of predictive models, enabling researchers and professionals to make more informed decisions based on clearer and more representative data.
