# ResNet3D-34 for Tornado Detection

A larger 3D CNN variant trained on temporal dual-polarimetric NEXRAD radar sequences. This is the **64M parameter** version -- see [resnet3d-18-tornet](https://huggingface.co/deepguess/resnet3d-18-tornet) for the smaller, equally performant 33M version.

## Model Description

Same dual-head architecture as ResNet3D-18 but with deeper residual blocks (layers=[3,4,6,3]).

| Parameter | Value |
|-----------|-------|
| Backbone | ResNet3D-34 (BasicBlock, layers=[3,4,6,3]) |
| Parameters | 63.7M |
| Input shape | (B, 24, 8, 128, 128) |
| Output shape | (B, 4) |

## Performance

### Test Set (3,685 events)

| Head | AUC | CSI | F1 | Precision | Recall |
|------|-----|-----|-----|-----------|--------|
| Detection | 0.898 | 0.540 | 0.701 | 0.596 | 0.851 |
| Prediction | 0.988 | 0.865 | 0.928 | 0.924 | 0.932 |
| **Combined** | **0.943** | -- | -- | -- | -- |

### Key Finding

ResNet3D-34 (64M params) performs **nearly identically** to ResNet3D-18 (33M params) on this task (combined AUC 0.943 vs 0.942). The smaller model is recommended for deployment due to faster inference and lower memory usage.

## Training

| Parameter | Value |
|-----------|-------|
| Optimizer | AdamW (lr=1e-3) |
| Batch size | 512 |
| Epochs | 20 |
| GPU | NVIDIA H200 (144GB) |

## Usage

Same as ResNet3D-18 -- see [resnet3d-18-tornet](https://huggingface.co/deepguess/resnet3d-18-tornet) for full usage instructions and deployment guidance.

```python
from model_resnet3d import DualHeadResNet3D
model = DualHeadResNet3D(in_channels=24, arch="resnet34")
state = torch.load("best.pt", map_location="cpu")
model.load_state_dict(state["model_state_dict"])
```
