Feature extraction is a process in machine learning where relevant and informative features are selected or extracted from raw data. It involves transforming the input data into a more compact representation that captures the essential characteristics for a particular task. Feature extraction is often performed to reduce the dimensionality of the data, remove noise, and highlight relevant patterns, improving the performance and efficiency of machine learning models. Techniques such as Principal Component Analysis (PCA), wavelet transforms, and deep learning-based methods can be used for feature extraction.
