How to do 3-patch ensemble?

[hujun100]

Hi, Can you tell us the way to do 3-path ensemble? Thanks

Please see Appendix H in SphereFace paper (http://wyliu.com/papers/LiuCVPR17v3.pdf).

@wy1iu Are these 3-patch ensembles have the same network architecture, and different input as a different alignment applied to each input. Or each ensemble has different architecture.

When should we apply different alignment on the input at training, or just in inference, or both of them?

[wy1iu]

the network architectures are the same. The only thing that is different is the cropped patch.
