train streaming data and make predictionsIn the following example, we train a perceptron to categorize the datasets of 20 news categories. This data set of 20 Web news sites collects nearly 20,000 news articles. This data set is often used for document classification and clustering experiments, and Scikit-learn provides an easy way to download and read datasets. We will train a perceptron to identify three

then applying them to new data. This is why it is common practice to evaluate an algorithm in machine learning by splitting the dataset into two datasets, one of which is called the training set, which is used to learn the properties of the data, and the other is called the test set, which tests those properties on the test set.loading a sample data setScikit-le

SummaryClustering is unsupervised learning ( unsupervised learning does not rely on pre-defined classes or training instances with class tags), it classifies similar objects into the same cluster, it is observational learning, rather than example-based learning, which is somewhat like a fully automated classification.
8 tactics to Combat imbalanced Classes on Your machine learning Datasetby Jason Brownlee on August learning ProcessHave this happened?You is working on your dataset. You create a classification model and get 90% accuracy immediately. "Fantastic" you think. You dive a little deeper and discover this 90% of the data belongs to one class. damn!This is a example of a
