（二十五）sklearn 偏最小二乘回归

参考博客 Python偏最小二乘回归(PLSR)测试
EXAMPLE

from sklearn.cross_decomposition import PLSRegression

X = [
    [0., 0., 1.],
    [1., 0., 0.],
    [2., 2., 2.],
    [2., 5., 4.]
]

Y =[
    [0.1, -0.2],
    [0.9, 1.1],
    [6.2, 5.9],
    [11.9, 12.3]
]

pls2 = PLSRegression(n_components=2)
for i in range(1000):
    pls2.fit(X, Y)

Y_pred = pls2.predict(X)

print(Y_pred)
