Appendices The whole appendix is organized as follows

The whole appendix is organized as follows. In Appendix C, we describe the the experimental settings for Section 4 in detail. Now the circular convolution can also be written in a simpler matrix-vector product form. Proposition A.1 The spectral norm of Q introduced in (8) can be bounded by nullQ null null null null null More specifically, Appendix B.1 provides the Hence in Appendix B.2 and Appendix B.3, we discuss in detail on how to deal with this difference in Additionally, in Appendix B.4 and Appendix B.5, we include other implementation details, From our discussion in Section 3, we can see that all the operations can be efficiently implemented in the frequency domain via 2D FFTs. It should be noted that modern ConvNets often use cross-correlation rather than the circular convolution.
