# batchSize

The number of examples to use per mini-batch.

## Declaration

```swift
var batchSize: Int
```

## Discussion

Discussion A larger batch size will speed up computation when training, as long as the batch fits in memory. note: This parameter is only used by the fitted method. When using the update method it’s up to you to do batching.
