Notebook for Rotation Equivariance

'Demo for Rotataion Equivariance' shows the main property of proposed method. Go through the notebook and you will observe rotation equivariance in output feature maps, e.g.,

Test Pretrained Models

Test 6-layer CNN(M=32) [Acc=96.87%]

./test.sh CNN 6

Test 6-layer RotDCF(M=16, =8, K=5, =5) [Acc=99.01%]

change M=16, =8, K=5, and =5 in test.sh, and then,

./test.sh RotDCF 6 

Test 6-layer DCF(M=32, K=5) [Acc=96.94%]

change K=5 in test.sh, and then,

./test.sh DCF 6 

Train New Models

Train 6-layer CNN(M=32)

./train.sh CNN 6

Train 6-layer RotDCF(M=16, =8$, K=5, =5)

change M=16, =8, K=5, and =5 in train.sh, and then,

./train.sh RotDCF 6 

Train 6-layer DCF(M=32, K=5)

change K=5 in train.sh, and then,

./train.sh DCF 6
