V-2 Clustering with Kmeans: Normalize our data, Does it improve it? | Python | Unsupervised learning

Are you ready to learn about Kmeans? Does normalization of our data improves k-means performance? #python #k-means #kmeans In this super chapter, we'll cover the discovery of clusters or groups through the partitioning algorithm K-means with python and the JUPYTER NOTEBOOK. Pandas libraries for data manipulation, matplotlib for creation of graphics, sklearn for calling the clustering function KMeans. Video #2: What is Kmeans? Why should we normalize our data before clustering? What is the difference between scaling and normalization? How normalization works? Formulas for normalization and scale: min, max, normal distribution, standard deviation Graphics of cluster with scatterplots: No normalized data vrs normalized data Discussion of results of No normalized data and clustering vrs normalized data and clusters Video #1:    • V-1: Clustering with Kmeans in Python: Skl...   How the algorithm Kmeans works?
