Chapter 4 Classification of Bauxites
01/01/1972Autochthonous or allochthonous origin Bauxites may be grouped as follows: ( I ) autochthonous bauxites on fresh igneous, metamorphic and sedimentary rocks: (a) primary formations; (b) fossil, polygenetic, altered bauxites; (2) allochthonous bauxite sediments: (a) coarse clastic bauxite sediments; (6) fine clastic-colloidal bauxite sediments.

Is Stochastic gradient descent a classifier or an optimizer?
SGDClassifier is a Linear classifiers (SVM, logistic regression, a.o.) with SGD training. This estimator implements regularized linear models with stochastic gradient descent (SGD) learning: the gradient of the loss is estimated each sample at a time and the model is updated along the way with a decreasing strength schedule (aka learning rate).
