Alternatively, general dimensionality reduction techniques are used such as:
Read moreWhich algorithm is used for feature extraction?
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.
