Redução de dimensão usando PCA
# Import PCA
from sklearn.decomposition import PCA
# Create a PCA instance with 2 components: pca
pca = PCA(n_components= ...)
# Fit the PCA instance to the scaled samples
pca.fit(scaled_samples)
# Transform the scaled samples: pca_features
pca_features = pca.transform(scaled_samples)
# Print the shape of pca_features
print(pca_features.shape)
