Claim 1:
2. The fraud prevention system of claim 1, wherein, to perform the feature encoding on the one or more categorical variables in the first matrix to generate the one or more feature encoded categorical variables, the electronic processor is further configured to
determine an average feature value of one of the numerical features in the training dataset for one of the one or more categorical variables,
determine a number of times the one of the one or more categorical variables was recorded in the training dataset,
determine a population average feature value of the one of the numerical features across a specific time period in the training dataset, and
adjust the average feature value based on the number of times the one of the one or more categorical variables was recorded in the training dataset and the population average feature value.
