resnet50-binary-0001¶

Use Case and High-Level Description¶

This is a classical classification network for 1000 classes trained on ImageNet. The difference is that most convolutional layers were replaced by binary once that can be implemented as XNOR+POPCOUN operations. Only input, final and shortcut layers were kept as FP32, all the rest convolutional layers are replaced by BinaryConvolution layers.

Specification¶

Metric	Value
Image size	224x224
fp32 conv MFlops	960
bin conv MI1ops	7218
Source framework	PyTorch*

Accuracy¶

The quality metrics calculated on ImageNet validation dataset is 70.69% accuracy

Metric	Value
Accuracy top-1 (ImageNet)	70.69%

Inputs¶

A blob with a BGR image and the shape 1, 3, 224, 224 in the format B, C, H, W, where:

B – batch size
C – number of channels
H – image height
W – image width

It is supposed that input is BGR in 0..255 range

Outputs¶

The output is a blob with the shape 1, 1000 in the format B, C, where:

B - batch size
C - predicted probabilities for each class in logits format

Demo usage¶

The model can be used in the following demos provided by the Open Model Zoo to show its capabilities:
