Instead of updating m j by computing the mean, we use stochastic gradient descent, to remodel the mi such that : m i = m
Instead of updating by computing the mean, we use stochastic gradient descent, to remodel the mi such that : with learning rate step size Recall that in the update step of the standard Kmean algorithm, we assign each cluster centre to be the mean centroid of the data points closest to that centre. It turns out that a particular choice of the learning rate which may be different for each cluster makes the two algorithms batch gradient descent and the standard kmeans algorithm have identical update steps. Let's focus on the update for the first cluster, with center d Implement the equation instead of mean in the standard algorithm and find the learning rate value, such that the value of both algorithms perform the same update for marks
