Working with categorical values with one-hot encoding

Machine learning and statistics can be quite good at determining relationships between numbers. But what if you have a feature that is categorical and doesn't have a relationship? The definition of a categorical feature is when the variable is a label or category with discrete possibilities, such as colors , the animal kingdom, or cities.

One option when you have this type of data is to use use one-hot encoding. This is the process of converting a categorical value into a set of ones and zeroes so that the model can interpret them as independent, but not infer that there is a relationship between them. This also prevents the inference that some categories are superior or inferior.
