K Means algorithm | part 1 | KMeans Clustering | Supervised vs Unsupervised learning | tamil
k-means clustering aims to partition n observations into k clusters in which each observation belongs to the cluster with the nearest mean (cluster centers or cluster centroid), serving as a prototype of the cluster.

How to find the mean of data points which has 2 values ( x ,y ) for each data point ( average of all observations) ?

Add up all the x values and divide the result by the total number of data points. This gives you the average x value. Add up all the y values and divide the result by the total number of data points. This gives you the average y value. The mean of the data points is the pair (average x value, average y value).
Good session . One small suggestion is that the voice is running fast.

Bro first iteration la centroids value enna bro?

Video timeline 09:20 la 2 inverted triangles randomly initialized centroid . if k value is 2 , First iteration la randomly edachu 2 places centroid point ah vechukalam if k value is 3 , First iteration la randomly edachu 3 places centroid point ah vechukalam ... etc since random ah place panradunala it better to place those random 2 centroid point at extremes ends so that they will be far from each other than to place them both near to each other this will help to group points and form cluster . Reference : scikit-learn.org/stable/modules/generated/sklearn.cluster.KMeans.html "‘random’: choose n_clusters observations (rows) at random from data for the initial centroids."
