Based on prior knowledge, it appears that the feature "other_parties" does not have a strong relationship with the task of determining whether a person receives a credit. The three possible categories for this feature are "none", "guarantor", and "co applicant". It is likely that individuals with different "other_parties" values can both receive or not receive credit. Therefore, the dictionary includes all three categories for both the "yes" and "no" classes.
