# Panda — interaction panoptic detector

Query-based panoptic detector grouping LArTPC points into interactions (masked cross-attention decoder over a PTv3 backbone).

- **pimm type:** `detector-v4` · 12 queries · 2 classes

## Loading

```python
import pimm
model = pimm.from_pretrained("hf://deeplearnphysics/panda-interaction")
```

Architecture + hyper-parameters travel in `config.json`, so no config file is
needed. Weights are bitwise-identical to the original checkpoint.

## Provenance

Repackaged from the original [`panda`](https://github.com/DeepLearnPhysics/panda) checkpoints into the [`pimm`](https://github.com/youngsm/particle-imaging-models) export format. Inherits the source repo's license.
