Description: Incremental PCA, or Incremental Principal Component Analysis, is a variant of traditional PCA that allows for the incremental updating of the model, meaning it can adapt without needing to recalculate the entire model each time new data is added. This technique is particularly useful in situations where datasets are large or constantly changing, making full processing impractical or inefficient. Unlike standard PCA, which requires all data to be available beforehand, Incremental PCA can adapt to real-time data streams, making it a valuable tool in online data analysis and machine learning applications. Its implementation is based on singular value decomposition (SVD) and allows for maintaining the structure of the data while reducing its dimensionality, thus facilitating visualization and analysis. This technique not only improves computational efficiency but also enables analysts and data scientists to work with frequently changing data, maintaining the relevance and accuracy of the model over time.
