Sklearn kmeans prediction

Webb20 jan. 2024 · The point at which the elbow shape is created is 5; that is, our K value or an optimal number of clusters is 5. Now let’s train the model on the input data with a number of clusters 5. kmeans = KMeans (n_clusters = 5, init = "k-means++", random_state = 42 ) y_kmeans = kmeans.fit_predict (X) y_kmeans will be: Webb26 okt. 2024 · But these are not real label of each image, since the output of the kmeans.labels_ is just group id for clustering.
