Willkommen!

This is my repository of studies on Machine Learning.
Here you'll find examples of Machine Learning exercises for the types of models:    

• Linear Regression

from sklearn import datasets, linear_model
from sklearn.metrics import mean_squared_error, r2_score
from sklearn.model_selection import train_test_split


• Decision Tree and Random Forest

from sklearn import tree
from sklearn.tree import DecisionTreeClassifier, export_graphviz
from sklearn.ensemble import RandomForestClassifier
from sklearn.model_selection import train_test_split
from sklearn.preprocessing import StandardScaler
from sklearn.metrics import classification_report, accuracy_score, confusion_matrix, r2_score, mean_squared_error
import graphviz


• k-Nearest Neighbors

from sklearn.preprocessing import StandardScaler
from sklearn.model_selection import train_test_split
from sklearn.neighbors import KNeighborsClassifier
from sklearn.metrics import classification_report,confusion_matrix
