It is effectively Singlar Value Deposition (SVD) in linear algebra and it is so powerful and elegant that usually deemed as the crown drews of linear algebra. The second consists of applying a Stacked Denoising Auto-Encoder classifier to the output of the best of the previous designs, trying to take advantage of the limitations of CNN architectures. 1 infrastructure layer function assembly View layer Visualization of calculation chart TensorBoard Workflow layer Dataset preparation, storage, loading keras/TF Slim Calculation layer Construction of calculation graph and optimization of forward calculation / backward propagation TensorFlow Core 0. In addition, we are sharing an implementation of the idea in Tensorflow.
