| # HENet-tinyE |
|
|
| HENet uses depthwise conv to build lightweight blocks with LayerScale for stable training; the tiny-E configuration has widths 48/96/192/384 and depths 3/3/8/6, with parameter count in the tiny range. |

| ## Model Overview |
| |
| ### Core Design |
| |
| HENet uses depthwise conv to build lightweight blocks with LayerScale for stable training; the tiny-E configuration has widths 48/96/192/384 and depths 3/3/8/6, with parameter count in the tiny range. |
| |
| - **Task type**: Image Classification. |
| - **backbone**: HENet (tiny-E configuration, `depth/block_nums=[3,3,8,6]`, `width/embed_dims=[48,96,192,384]`, `block_cls=["DWCB","GroupDWCB","AltDWCB","DWCB"]`, GELU activation, LayerScale, S2D downsampling, `num_classes=1000`), uses depthwise conv to build lightweight blocks with LayerScale for stable training. |
| - **neck**: — (HENet has a built-in fully connected classification head; no separate neck). |
| - **classification head**: HENet built-in fully connected classification head (`include_top=True`, `feature_mix_channel=1024`). |
| - **Loss function**: `SoftTargetCrossEntropy` (soft-label cross-entropy with mixup). |
| - **Model input**: single RGB image at resolution `224 × 224` (`1x3x224x224`). |
| - **Model output**: 1000-class prediction logits; argmax gives the predicted class. |
