Automated feature extraction methods Autoencoders, wavelet scattering, and deep neural networks are commonly used to extract features and reduce dimensionality of the data.
Read moreWhy is CNN better for feature extraction?
CNN provides better image recognition when its neural network feature extraction becomes deeper (contains more layers), at the cost of the learning method complexities that had made CNN inefficient and neglected for some time.
Read moreHow do you choose a feature extraction method for machine learning?
Feature Selection: Select a subset of input features from the dataset.
Read moreWhich is the best method for feature extraction?
Principal Component Analysis (PCA) and Independent Component Analysis (ICA) were the two best methods at extracting representative features, followed by Dictionary Learning (DL) and Non-Negative Matrix Factorization (NNMF).

When plotted, many time series exhibit one or more of the following features:
