WebIn backpropagation implementation, it seems like a norm to unroll (make the thetas as an one-dimensional vectors) thetas and then pass them as a parameter to the cost function. def NNCostFunction (unrolled_thetas, input_layer_size, hidden_layer_size, num_labels, X, y): # **ROLL AGAIN** unrolled_thetas to theta1, theta2 (3 layer assumption ... WebMay 28, 2024 · For instance, a deep learning method is proposed for noise reduction in order to allow low-dose PET imaging protocols [9] [10] [11]. A neural network is integrated into … WebPET image reconstruction is challenging due to the ill-poseness of the inverse problem and limited number of detected photons. Recently deep neural networks have been widely applied to medical imaging denoising applications. In this work, based on the MAPEM algorithm, we propose a novel unrolled neural network framework for 3D PET image … dc office people
