Based on prior knowledge and analysis, the feature "num_dependents" can potentially have a relationship with the task of determining whether a person receives credit or not. 

Here is the generated dictionary:

```json
{
	"yes": [0.0, 1.0, 2.0, 3.0, 4.0],
	"no": [0.0, 1.0, 2.0, 3.0, 4.0]
}
```

The values for "num_dependents" can vary between 0.0 to 4.0 for both the target classes ('yes' and 'no'). This indicates that the presence or absence of credit does not seem to be strongly correlated with the number of dependents.
