and it demonstrates the offset value on the x-direction and the y-direction respectively. A convolutional layer is responsible for learning the 2D offsets and output the deformed feature map using bilinear interpolation. For example, if the kernel is 3*3, there will be a feature...
因为P=0,S=1,而filter size与input volume size完全相同,所以两者仅仅做一次卷积:[7x7x512 与 7x7x512卷积得到1x1的2-d feature map]。又因为4096个filter,所以得到output volume立方体为[1x1x4096],也即4096-dim的vector。这个输出与K=4096的FC Layer完全相同 ...
Machine learning models are about predictive performance: Drug A increases successful outcomes by 17.83% with respect to drug B for people with age X, but 22.34% for people with age Y. Machine learning models are often much more powerful for prediction than statistical models, but they are not...
