1. A method comprising: determining a microscale metric for a plurality of microscale interaction types; determining a mesoscale metric for a plurality of mesoscale interaction types, wherein a value of the mesoscale metric for each mesoscale interaction type is based on a corresponding function of values of the microscale metric for the plurality of the microscale interaction types; obtaining a plurality of observations that indicate the values of the mesoscale metric for the plurality of mesoscale interaction types; and determining values of the microscale metric for the plurality of microscale interaction types based on the plurality of observations and the corresponding functions and compressed sensing.
