# maxCount

The largest number of similar items the model stores for each item.

## Declaration

```swift
var maxCount: Int
```

## Discussion

Discussion The memory Create ML requires to train this model is proportional to this number. A lower value reduces its demand for memory but decreases the recommender’s accuracy. The default value is 64.
