After analyzing the relationship between the feature "poutcome" and the task of whether the client subscribes to a term deposit, here is the dictionary representing the relationship:

```json
{
	"no": ["unknown", "failure"],
	"yes": ["success", "other"]
}
```

The target class "no" (not subscribing to a term deposit) is associated with the values "unknown" and "failure" of the feature "poutcome". On the other hand, the target class "yes" (subscribing to a term deposit) is associated with the values "success" and "other" of the feature "poutcome".
