# "The Elements of Statistical Learning" Notebooks

Reproducing examples from the "The Elements of Statistical Learning" by Trevor Hastie, Robert Tibshirani and Jerome Friedman with Python and its popular libraries: 

**numpy**, **math**, **scipy**, **sklearn**, **pandas**, **tensorflow**, **statsmodels**, **sympy**, **catboost**, **pyearth**, **mlxtend**, **cvxpy**. Almost all plotting is done using **matplotlib**, sometimes using **seaborn**.
