The idea is encoding your categorical variable with the use of target variable (continuous or categorical depending on the task). For example, if you have regression task, you can encode your categorical variable with the mean of the target.

In my experience with supervised learning, improving the model performance from decent to human-like requires creative feature engineering. Jumping from simple algorithms to complex ones does not always boost performance if the feature engineering is not done … WebAug 13, 2024 · Dummy coding scheme is similar to one-hot encoding. This categorical data encoding method transforms the categorical variable into a set of binary variables (also known as dummy variables). In the case of one-hot encoding, for N categories in a variable, it uses N binary variables. The dummy encoding is a small improvement over …
