WebNov 28, 2024 · Optical Phase Dropout in Diffractive Deep Neural Network. Unitary learning is a backpropagation that serves to unitary weights update in deep complex-valued neural network with full connections, meeting a physical unitary prior in diffractive deep neural network ( [DN]2). However, the square matrix property of unitary weights induces that the ... WebJul 4, 2024 · We calculate the dielectric function within the framework of the random-phase approximation (RPA) based on DFT ground-state calculations, starting from eigenvectors and eigenvalues. The final goal of our theoretical work is a comparison to corresponding experimental data. We compare our computational results with optical measurements on …

WebFeb 18, 2024 · In the forward phase dropout mask activations with a random tensor of 1s and 0s to force net to learn the average of the weights. This help the net to generalize better. But during the update phase of the gradient descent the activations are not masked. This to me seems counter intuitive. WebJun 4, 2024 · To prevent overfitting in the training phase, neurons are omitted at random. Introduced in a dense (or fully connected) network, for each layer we give a probability p of dropout. At each iteration, each neuron has a probability p of being omitted.
