定义一个基本函数来绘制人脸画廊。

n_row, n_col = 2, 3
n_components = n_row * n_col
image_shape = (64, 64)


def plot_gallery(title, images, n_col=n_col, n_row=n_row, cmap=plt.cm.gray):

        nrows=n_row,

        im = ax.imshow(
            vec.reshape(image_shape),
            cmap=cmap,
            interpolation="nearest",
            vmin=-vmax,
            vmax=vmax,

让我们看看我们的数据。灰色表示负值，白色表示正值。

分解

初始化不同的分解估计器，并在所有图像上拟合每个估计器并绘制一些结果。每个估计器提取 6 个分量作为向量 \(h \in \mathbb{R}^{4096}\)。我们只是将这些向量以 64x64 像素图像的人性化可视化方式显示出来。

在 用户指南 中阅读更多内容。

特征脸 - 使用随机 SVD 的 PCA

使用数据的奇异值分解 (SVD) 进行线性降维，将其投影到较低维空间。

注意

特征脸估计器通过 sklearn.decomposition.PCA 还提供了一个标量 noise_variance_（按像素计算的方差平均值），它不能以图像形式显示。

pca_estimator = decomposition.PCA(
    n_components=n_components, svd_solver="randomized", whiten=True
)
pca_estimator.fit(faces_centered)
plot_gallery(
    "Eigenfaces - PCA using randomized SVD", pca_estimator.components_[:n_components]
)

非负分量 - NMF

估计非负原始数据作为两个非负矩阵的乘积。

nmf_estimator = decomposition.NMF(n_components=n_components, tol=5e-3)
nmf_estimator.fit(faces)  # original non- negative dataset
plot_gallery("Non-negative components - NMF", nmf_estimator.components_[:n_components])

独立分量 - FastICA

独立分量分析将多元向量分离为最大限度独立的加性子分量。

ica_estimator = decomposition.FastICA(
    n_components=n_components, max_iter=400, whiten="arbitrary-variance", tol=15e-5
)
ica_estimator.fit(faces_centered)
plot_gallery(
    "Independent components - FastICA", ica_estimator.components_[:n_components]
)

稀疏分量 - MiniBatchSparsePCA

Mini-batch 稀疏 PCA (MiniBatchSparsePCA) 提取最能重建数据的稀疏分量集。此变体比类似的 SparsePCA 更快，但精度较低。

batch_pca_estimator = decomposition.MiniBatchSparsePCA(
    n_components=n_components, alpha=0.1, max_iter=100, batch_size=3, random_state=rng
)
batch_pca_estimator.fit(faces_centered)
plot_gallery(
    "Sparse components - MiniBatchSparsePCA",
    batch_pca_estimator.components_[:n_components],
)

字典学习

默认情况下，MiniBatchDictionaryLearning 将数据划分为 mini-batches，并通过在 mini-batches 上循环指定的迭代次数以在线方式进行优化。

batch_dict_estimator = decomposition.MiniBatchDictionaryLearning(
    n_components=n_components, alpha=0.1, max_iter=50, batch_size=3, random_state=rng
)
batch_dict_estimator.fit(faces_centered)
plot_gallery("Dictionary learning", batch_dict_estimator.components_[:n_components])

聚类中心 - MiniBatchKMeans

sklearn.cluster.MiniBatchKMeans 具有计算效率，并使用 partial_fit 方法实现在线学习。这就是为什么使用 MiniBatchKMeans 来增强一些耗时算法可能是有益的。

kmeans_estimator = cluster.MiniBatchKMeans(
    n_clusters=n_components,
    tol=1e-3,
    batch_size=20,
    max_iter=50,
    random_state=rng,
)
kmeans_estimator.fit(faces_centered)
plot_gallery(
    "Cluster centers - MiniBatchKMeans",
    kmeans_estimator.cluster_centers_[:n_components],
)

因子分析分量 - FA

FactorAnalysis 与 PCA 相似，但其优点在于独立地对输入空间中每个方向的方差进行建模（异方差噪声）。在 用户指南 中阅读更多内容。

fa_estimator = decomposition.FactorAnalysis(n_components=n_components, max_iter=20)
fa_estimator.fit(faces_centered)
plot_gallery("Factor Analysis (FA)", fa_estimator.components_[:n_components])

# --- Pixelwise variance
plt.figure(figsize=(3.2, 3.6), facecolor="white", tight_layout=True)
vec = fa_estimator.noise_variance_
vmax = max(vec.max(), -vec.min())
plt.imshow(
    vec.reshape(image_shape),
    cmap=plt.cm.gray,
    interpolation="nearest",
    vmin=-vmax,
    vmax=vmax,
)
plt.axis("off")
plt.title("Pixelwise variance from \n Factor Analysis (FA)", size=16, wrap=True)
plt.colorbar(orientation="horizontal", shrink=0.8, pad=0.03)
plt.show()

分解：字典学习

在接下来的部分中，让我们更精确地考虑 字典学习。字典学习是一个问题，它旨在将输入数据稀疏表示为简单元素的组合。这些简单元素构成一个字典。可以约束字典和/或编码系数为正以匹配数据中可能存在的约束。

MiniBatchDictionaryLearning 实现了字典学习算法的一个更快但精度较低的版本，更适合于大型数据集。在 用户指南 中阅读更多内容。

使用另一种颜色图绘制来自我们数据集的相同样本。红色表示负值，蓝色表示正值，白色表示零。

plot_gallery("Faces from dataset", faces_centered[:n_components], cmap=plt.cm.RdBu)

与前面的示例类似，我们更改参数并训练 MiniBatchDictionaryLearning 估计器在所有图像上。通常，字典学习和稀疏编码将输入数据分解为字典和编码系数矩阵。 \(X \approx UV\)，其中 \(X = [x_1, . . . , x_n]\)，\(X \in \mathbb{R}^{m×n}\)，字典 \(U \in \mathbb{R}^{m×k}\)，编码系数 \(V \in \mathbb{R}^{k×n}\)。

下面是当字典和编码系数都受到正约束时的结果。

字典学习 - 正向字典

在以下部分中，我们在寻找字典时强制执行正性。

dict_pos_dict_estimator = decomposition.MiniBatchDictionaryLearning(
    n_components=n_components,
    alpha=0.1,
    max_iter=50,
    batch_size=3,
    random_state=rng,
    positive_dict=True,
)
dict_pos_dict_estimator.fit(faces_centered)
plot_gallery(
    "Dictionary learning - positive dictionary",
    dict_pos_dict_estimator.components_[:n_components],
    cmap=plt.cm.RdBu,
)

字典学习 - 正向代码

下面我们约束编码系数为正矩阵。

dict_pos_code_estimator = decomposition.MiniBatchDictionaryLearning(
    n_components=n_components,
    alpha=0.1,
    max_iter=50,
    batch_size=3,
    fit_algorithm="cd",
    random_state=rng,
    positive_code=True,
)
dict_pos_code_estimator.fit(faces_centered)
plot_gallery(
    "Dictionary learning - positive code",
    dict_pos_code_estimator.components_[:n_components],
    cmap=plt.cm.RdBu,
)
