示例1: StandardScaler

# 需要導入模塊: from sklearn.preprocessing import StandardScaler [as 別名]
# 或者: from sklearn.preprocessing.StandardScaler import flatten [as 別名]
normalizeFeatures = 'Mean'
if normalizeFeatures == 'MeanAndStd':
    X_std = StandardScaler().fit_transform(vecPosMatrix)
elif normalizeFeatures == 'Mean':
    X_std = vecPosMatrix - np.mean(vecPosMatrix,0)

print "Making sklearn_pca"
nComponents = 10
sklearn_pca = sklearnPCA(n_components=nComponents)
print "Making Y_sklearn"

# An important note -- we get a hash value for the raw data here
# as a unique identifier of this dataset. Then we save the initial
# PCA object to disk to reduce time on subsequent runs.

sklearn_pca_hash = str(hash(tuple(X_std.flatten()[::100])))[-10:]
#pca_result_hash = 'y_sklearn_hash_%s.cpickle' %(sklearn_pca_hash)
pca_result_hash = 'pca_obj_hash_%s.cpickle' %(sklearn_pca_hash)
if not(os.path.exists(pca_result_hash)):
    #Y_sklearn = sklearn_pca.fit_transform(X_std)
    sklearn_pca.fit(X_std)
    with open(pca_result_hash,'wb') as of:
        cPickle.dump(sklearn_pca, of)
    Y_sklearn = sklearn_pca.transform(X_std)
    #with open(pca_result_hash,'wb') as of:
    #    cPickle.dump(Y_sklearn, of)
else:
    #Y_sklearn = cPickle.load(open(pca_result_hash))
    sklearn_pca = cPickle.load(open(pca_result_hash))
    Y_sklearn = sklearn_pca.transform(X_std)
