WebSep 28, 2024 · One hot encoding data is one of the simplest, yet often misunderstood data preprocessing techniques in general machine learning scenarios. The process binarizes categorical data with ‘N’ distinct categories into N columns of binary 0’s and 1’s. Where the presence of a 1 in the ‘N’th category indicates that the observation belongs to that category. http://www.iotword.com/6055.html
