📄️ simRecommend Data Type Specifications

Data Type Specifications tell the model what form the data from each column is in so it knows how to properly compare values. Unlike other models, the class column will be set to "CLASS\ITEM\SET". This item set must be duplicated in the data set, with the duplicated column type set to "ITEM\_SET". The item set being described here is what will tell the model the individual's historical preferences. More detail on the format of the item set will come in later sections.
