Давайте посмотрим на наши данные. Серый цвет указывает на отрицательные значения, белый указывает на положительные значения.

Разложение#

Инициализировать различные оценщики для декомпозиции и обучить каждый из них на всех изображениях, а затем построить некоторые результаты. Каждый оценщик извлекает 6 компонентов в виде векторов \(h \in \mathbb{R}^{4096}\). Мы просто отобразили эти векторы в удобной для человека визуализации как изображения 64x64 пикселей.

Подробнее в Руководство пользователя.

Собственные лица - PCA с использованием рандомизированного SVD#

Линейное снижение размерности с использованием сингулярного разложения (SVD) данных для проецирования в пространство меньшей размерности.

Примечание

Оценщик Eigenfaces, через sklearn.decomposition.PCA, также предоставляет скаляр noise_variance_ (среднее значение дисперсии по пикселям), которое не может быть отображено как изображение.

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]
)

Неотрицательные компоненты - NMF#

Оценить неотрицательные исходные данные как произведение двух неотрицательных матриц.

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])

Независимые компоненты - FastICA#

Анализ независимых компонент разделяет многомерный вектор на аддитивные подкомпоненты, которые максимально независимы.

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]
)

Разреженные компоненты - MiniBatchSparsePCA#

Мини-пакетный разреженный PCA (MiniBatchSparsePCA) извлекает набор разреженных компонентов, которые лучше всего восстанавливают данные. Этот вариант быстрее, но менее точен, чем аналогичный SparsePCA.

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],
)

Словарное обучение#

По умолчанию, MiniBatchDictionaryLearning разделяет данные на мини-пакеты и оптимизирует в онлайн-режиме, циклически перебирая мини-пакеты заданное количество итераций.

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])

Центры кластеров - MiniBatchKMeans#

sklearn.cluster.MiniBatchKMeans вычислительно эффективен и реализует онлайн-обучение с partial_fit метод. Именно поэтому может быть полезно улучшить некоторые трудоёмкие алгоритмы с помощью MiniBatchKMeans.

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],
)

Компоненты факторного анализа - FA#

FactorAnalysis похож на PCA но имеет преимущество моделирования дисперсии в каждом направлении входного пространства независимо (гетероскедастичный шум). Подробнее в Руководство пользователя.

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()

Декомпозиция: Словарное обучение#

В следующем разделе рассмотрим Словарное обучение более точно. Словарное обучение — это задача, которая сводится к поиску разреженного представления входных данных в виде комбинации простых элементов. Эти простые элементы образуют словарь. Можно ограничить словарь и/или кодирующие коэффициенты положительными значениями, чтобы соответствовать ограничениям, которые могут присутствовать в данных.

MiniBatchDictionaryLearning реализует более быструю, но менее точную версию алгоритма словарного обучения, которая лучше подходит для больших наборов данных. Подробнее в Руководство пользователя.

Постройте те же образцы из нашего набора данных, но с другой цветовой картой. Красный указывает на отрицательные значения, синий — на положительные, а белый представляет нули.

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

Аналогично предыдущим примерам, мы изменяем параметры и обучаем MiniBatchDictionaryLearning оценщик на всех изображениях. Обычно обучение словаря и разреженное кодирование разлагают входные данные на матрицы словаря и кодирующих коэффициентов. \(X \approx UV\), где \(X = [x_1, . . . , x_n]\), \(X \in \mathbb{R}^{m×n}\), словарь \(U \in \mathbb{R}^{m×k}\), кодирующие коэффициенты \(V \in \mathbb{R}^{k×n}\).

Также ниже приведены результаты, когда словарь и коэффициенты кодирования положительно ограничены.

Словарное обучение - положительный словарь#

В следующем разделе мы обеспечиваем положительность при нахождении словаря.

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,
)

Dictionary learning - positive dictionary

Словарное обучение - положительный код#

Ниже мы ограничиваем коэффициенты кодирования как положительную матрицу.

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,
)
