Metadata Incorporation

Problem

Different counties have different demographic distributions and geo-spatial properties. Therefore spread of infection varies a lot based on the size of the county, population density, population age, industries, etc. Factors we want to consider

• Age (mean or median)
• Population density
• Male to Female ratio
• Core industries
• Transportation methods
• Average income
• Racial makeup
• Building/Store spacing

Generating an embedding

Dummy supervised task

One setup is to train a model on a dummy supervised task then use the resulting intermediate representation.

Unsupervised approaches

Using raw features and fine-tuning

Another option is to simply create an embedder and train it with the rest of the model.
