K-meanCluster
How the K-mean Cluster work
Step 1. Begin with a decision the value of k = number of clusters
Step 2. Put any initial partition that classifies the data into k clusters. You may assign the training samples randomly, or systematically as the following:
Take the first k training sample as single-element clusters
Assign each of the remaining (N-k) training sample to the cluster with the nearest centroid. After each assignment, recomputed the centroid of the gaining cluster.
Step 3 . Take each sample in sequence and compute its distance from the centroid of each of the clusters. If a sample is not currently in the cluster with the closest centroid, switch this sample to that cluster and update the centroid of the cluster gaining the new sample and the cluster losing the sample.
Step 4 . Repeat step 3 until convergence is achieved, that is until a pass through the training sample causes no new assignments. (How the K-mean Cluster workStep 1.

Most countries are facing a multiplicity of challenges directly related to the
pr ent ways in which they currently generate and use energy. Human-induced climate
change, rising pollution levels, decreasing energy security, and resource wars are all
increasingly linked to the widespread use of non-renewable sources of energy. These
interrelated challenges present an ongoing and pressing policy-making dilemma to
develop and implement sound energy solutions. Evidence regarding the imperative need
for creative energy solutions is amassing a variety of reputable sources. The Fourth
Assessment Report by the Intergovernmental Panel on Climate Chance (IPCC) ranks
amongst the most salient of these sources. This IPCC report clearly points out that drastic
reductions in the use of fossil fuel use are essential to reduce greenhouse gas (GHG)
emissions to thereby minimize the most detrimental impacts of climate change.
