SqueezeNet: AlexNet-level accuracy with 50x fewer parameters and <0.5MB model size
SqueezeNet is a smaller CNN architectures which is comprised mainly of Fire modules and it achieves AlexNet-level
accuracy on ImageNet with 50x fewer parameters. SqueezeNet can offer at least three advantages: (1) Smaller CNNs require
less communication across servers during distributed training. (2) Smaller CNNs require less bandwidth to export a new
model from the cloud to an autonomous car. (3) Smaller CNNs are more feasible to deploy on FPGAs and other hardware with
limited memory. Additionally, with model compression techniques, SqueezeNet is able to be compressed to less than
0.5MB (510× smaller than AlexNet). Blow is macroarchitectural view of SqueezeNet architecture. Left: SqueezeNet ;

Here is the example for finetuning a pretrained squeezenet_1.0 on CIFAR10 dataset using Adam optimizer.
python train.py --model=squeezenet1_0 --pretrained --opt=momentum --lr=0.001 dataset=cifar10 --num_classes=10 --dataset_download
Detailed adjustable parameters and their default value can be seen in config.py.
To validate the model, you can use validate.py
. Here is an example for squeezenet_1.0 to verify the accuracy of
pretrained weights.
python validate.py --model=squeezenet1_0 --dataset=imagenet --val_split=val --pretrained
