from sklearn.cluster import KMeanskmeans = KMeans(n_clusters=3, random_state=9).fit(X_seeds) initial_result = kmeans.labels_ Since the resulting labels may not be the same as the ground truth labels, we have to map the two sets of labels. For this, we can use the following functi...
Use this notebook to identify natural clusters of customers.Oracle Machine Learningsupports clustering using several algorithms, including k-Means, O-Cluster, and Expectation Maximization. This notebook uses the CUSTOMERS data set from theSHschema using the unsupervised learning k-Means algorithm. The ...

Building a Categorical NB model is very similar to that of Gaussian NB but with one exception. Sklearn’s package requires variables to be in a numeric format; hence we need an additional step to encode variables of a type=’string’ to ‘numeric.’ It is done with just a couple of li...

Scikit-learn has been around a long time and would be most familiar to R programmers, but it comes with a big caveat: it is not built to run across a cluster. Spark ML is built for running on a cluster, since that is what Apache Spark is all about. ...
