The visit-level attention weight is displayed under visit ID, while all variable-level attention weights are associated with the ICD-9 codes. Bold values under visit ID indicate that the visit has a relatively higher visit-level attention weight. In the Weight column, bold values indicate that the corresponding ICD-9 code was assigned a relatively higher variable-level attention weight
