Based on prior knowledge, we can analyze the relationship between the "previous" feature and the task of whether the client subscribes to a term deposit.

Typically, we can expect that clients who have previously been contacted more times are less likely to subscribe to a term deposit, while clients who have been contacted fewer times are more likely to subscribe.

Here is a dictionary that presents the possible values of the "previous" feature for each target class:

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

Based on this analysis, we can see that both the "no" and "yes" target classes include the same typical previous values: 0.0, 1.0, 2.0, 3.0, and 4.0.
