Web26 okt. 2024 · Since the size of the MNIST dataset is quite large, we will use the mini-batch implementation of k-means clustering ( MiniBatchKMeans) provided by scikit-learn. This will dramatically reduce the amount of time it takes to fit the algorithm to the data. Here, we just choose the n_clusters argument to the n_digits (the size of unique labels, in ...
