The below example will use sklearn.decomposition.KernelPCA module on Sklearn digit dataset. Pastebin.com is the number one paste tool since 2002. %matplotlib inline import matplotlib.pyplot as plt import seaborn as sns; sns.set() import numpy as np from sklearn.cluster import KMeans from sklearn.datasets import load_digits digits = load_digits() digits.data.shape Output 1797, 64) This output shows that digit dataset is having 1797 samples with 64 features. The dataset contains a total of 1797 sample points. sklearn.datasets. Applying Support Vector Machine algorithm on load_digits dataset of sklearn import pandas as pd from sklearn.datasets import load_digits digits = load_digits () digits . Its perfection lies not only in the number of algorithms, but also in a large number of detailed documents […] from matplotlib import pyplot as plt. We will use Sklearn’ s load_digits dataset, which is a collection of 8x8 images (64 features)of digits. The size of the array is expected to be [n_samples, n_features]. The iris dataset is a classic and very easy multi-class classification dataset. The K-nearest neighbors algorithm is fast to train the data but is slow to compute the results. Digits dataset can be used for classification as well as clustering. import numpy as np import sklearn from sklearn.preprocessing import scale from sklearn.datasets import load_digits from sklearn.cluster import KMeans from sklearn import metrics. Pastebin.com is the number one paste tool since 2002. Chris Albon . Each feature is the intensity of one pixel of an 8 x 8 image. Each datapoint is a 8x8 image of a digit. load_digits #Display the first digit plt. Its perfection lies not only in the number of algorithms, but also in a large number of detailed documents […] DataFrames or Series as described below. classify). sklearn.datasets.load_digits sklearn.datasets.load_digits(n_class=10, return_X_y=False) [source] Load and return the digits dataset (classification). If True, the data is a pandas DataFrame including columns with ‘load_digits’ dataset contains ~1800 images of hand-written digits from 0 to 9. The number of classes to return.
