A schematic feature encoding scheme. Structured data, when used, comprises both categorical and numerical elements. We encoded the former using either indicators or an encoder module, whereas we packed the latter into a dense vector of values. Unstructured data (ie, textual notes) are encoded using a sparse (indicator) representation and then optionally run through an encoder module. Colors are stylistics only. The “+” denotes concatenation.
