StarNet
Category: Efficient/Mobile · Code: timm/models/starnet.py · Architectures: 7 · Pretrained weights: 4 (4 with ImageNet-1k results)
StarNet is a deliberately simple proof-of-concept network built around the star operation, the element-wise multiplication of two branches.

Usage
See the Quickstart for loading pretrained weights, image preprocessing and fine-tuning, and Feature Extraction for using the models as backbones.
>>> import timm
>>> model = timm.create_model('starnet_s4.in1k', pretrained=True)
>>> data_config = timm.data.resolve_model_data_config(model)Model API support
✓ supported, ✓ (square) works for square sizes only, ✗ not supported, – not needed (the model already accepts any input
size). Checked by running each feature on a randomly initialized model (StarNet with starnet_s050 at 224), other
architectures of the same class are expected to behave the same. See the Model API page for details.
Architectures
| Architecture | Params (M) | GMACs | Input size | Pretrained weights |
|---|---|---|---|---|
starnet_s1 | 2.87 | 0.42 | 224 | 1 |
starnet_s2 | 3.68 | 0.55 | 224 | 1 |
starnet_s3 | 5.75 | 0.76 | 224 | 1 |
starnet_s4 | 7.48 | 1.05 | 224 | 1 |
starnet_s050 | 0.54 | 0.09 | 224 | 0 |
starnet_s100 | 1.04 | 0.19 | 224 | 0 |
starnet_s150 | 1.56 | 0.23 | 224 | 0 |
GMACs and parameter counts are for the default input size and classifier of each architecture, from the benchmark results.
Pretrained weights
Top-1 is ImageNet-1k validation accuracy from results-imagenet.csv at
the listed eval size, - if the weight has no ImageNet-1k result (e.g. pretraining or image-text weights). Classes is the
size of the pretrained classifier, none for weights without one.
