K Means clustering with python code explained

K means clustering is another simplified algorithm in machine learning. It is categorized into unsupervised learning because here we don't know the result already (no idea about which cluster will be formed). This algorithm is used for vector quantization of the data and has been taken from signal processing methodology. Here the data is divided into several groups, data points in each group have similar characteristics. These clusters are decided by calculating the distance between data points.
