import numpy as np
from sklearn.decomposition import PCA
from sklearn.datasets import load_iris
# Загрузка данных
data = load_iris()
X = data.data
# Применение PCA для снижения размерности до 2 компонент
pca = PCA(n_components=2)
X_pca = pca.fit_transform(X)
print(X_pca[:5]) # Преобразованные данные
🗣️ В этом примере PCA снижает размерность данных Iris с 4 до 2 компонент. Это позволяет визуализировать данные и ускорить работу моделей, сохраняя основную информацию.🖥 Подробнее тут
