The feature extraction is entirely done using Python. We use the Pytorch package [53] to define and train the NNC. Our NN is a single hidden layer NN with 35 hidden nodes trained with the Adagrad [54] optimizer. Finally, in order to train the NNC to distinguish AD from NC patients ...
In this post you discovered feature selection for preparing machine learning data in Python with scikit-learn. You learned about 4 different automatic feature selection techniques: Univariate Selection. Recursive Feature Elimination. Principle Component Analysis. Feature Importance. If you are looking for ...
