WitrynaIt is designed to attack neural networks by leveraging the way they learn, gradients. The idea is simple, rather than working to minimize the loss by adjusting the weights based on the backpropagated gradients, the attack adjusts the input data to maximize the loss based on the same backpropagated gradients. WitrynaJ = imrotate (I,angle) rotates image I by angle degrees in a counterclockwise direction around its center point. To rotate the image clockwise, specify a negative value for angle. imrotate makes the output image J large enough to contain the entire rotated image. By default, imrotate uses nearest neighbor interpolation, setting the values of ... the others musicWitrynaPass in img and set the parameter orient as 'x' or 'y' to take either the x x or y y gradient.
