Questão 1311601

Analise o script python abaixo:

import pandas as pd

from sklearn.datasets import make_hastie_10_2

x, y = make_hastie_10_2(n_samples=6000,

random_state=42)

from sklearn.model_selection import train_test_split

x_train, x_test, y_train, y_test = train_test_split(x,

y, test_size=0.25,

random_state=42)

from sklearn.ensemble import RandomForestClassifier

clf = RandomForestClassifier( n_estimators=100,

oob_score=True, n_jobs=-1)

clf.fit(x_train, y_train)

y_pred_proba = clf.predict_proba(x_test)[:,1]

from sklearn.metrics import roc_curve

fpr, tpr, thr = roc_curve(y_test, y_pred_proba)

pd.DataFrame( {'FPR': fpr, 'TPR': tpr}

).set_index('FPR')['TPR'].plot(kind='line')
