K means from scratch python
Step 1.Randomly pick k data points as our initial Centroids. Step 2.Find the distance (Euclidean distance for our purpose) between each data points in our training set with the k centroids. Step 3.Now assign each data point to the closest centroid according to the distance found. Step 4.Update centroid location by taking … See more Let’s implement the above steps in code now. Import the numpy module and then go through the rest of the code here to get an understanding of how the K-Means clustering is … See more We will use the digits dataset (inbuilt within the sklearn module) for testing our function.
