How To Classify Data In Python using Scikit-learn

Classification is a large domain in the field of statistics and machine learning. Generally, classification can be broken down into two areas: 1. Binary classification, where we wish to group an outcome into one of two groups. 2. Multi-class classification, where we wish to group an outcome into one of … See more For binary classification, we are interested in classifying data into one of two binarygroups - these are usually represented as 0's and 1's in our data.
