example, you is going to generate an image of the Louvre Museum in Paris (content image C), mixed with a painting By Claude Monet, a leader of the Impressionist movement (style image S). Let's see how you can do this. 2-transfer Learning Neural Style Transfer (NST) uses a previously trained convolutional network, and builds on top of. The idea of using a

, where ' DW ', ' DB ' is for easy representation in Python code, and the real meaning is the right equation (differential): ' DW ' = DJ/DW = (dj/dz) * (DZ/DW) = x* (a-y) t/m ' db ' = dj/db = SUM (a-y)/M So the new values are: w = w–α* DW b = b–α* db, where alpha is the learning rate, with the new W, b in the next iteration. Set the number of iterations, after the iteration, is the final parameter W, b, using test cases to verify the recognition accur

Once you have done this, read our Getting Started chapter---it will introduce concept definitions, datasets, and methods to optimize the model using random gradient descent.A purely supervised learning algorithm can be read in the following order:Logistic regression-using Theano for something simpleMultilayer perceptron-introd

AA = Np.random.randn (3, 3= NP.RANDOM.RANDN (3, 1= a*bA. This will trigger the broadcast mechanism, so B is copied three times, becomes (3,3), * represents the matrix corresponding element multiplied, so the size of C will be (3, 3)B. This will trigger the broadcast mechanism, so B is duplicated three times,
