# helia_edge.layers.preprocessing.random_choice

Batchwise random layer choice with captured branches and owned RNG.

## helia_edge.layers.preprocessing.random_choice.RandomChoice

`class` · `python`

```python
RandomChoice(layers: list[keras.Layer], batchwise: bool = True, **kwargs={})
```

Choose one layer for a whole batch; branches must have compatible outputs.

Per-example layer choice was never implemented and remains unsupported.
The next-major default is the supported ``batchwise=True`` mode.
