In Depth: k-Means Clustering Python Data Science Handbook
WebClustering algorithms seek to learn, from the properties of the data, an optimal division or discrete labeling of groups of points. Many clustering algorithms are available in Scikit-Learn and elsewhere, but perhaps the simplest to understand is an algorithm known as k-means clustering, which is implemented in sklearn.cluster.KMeans. Webimage = img_to_array (image) data.append (image) # extract the class label from the image path and update the # labels list label = int (imagePath.split (os.path.sep) [- 2 ]) labels.append (label) # scale the raw pixel intensities to the range [0, 1] data = np.array (data, dtype= "float") / 255.0 labels = np.array (labels) # partition the data ...
