One of the reasons why DenseNet is less memory/speed-efficient than Wide ResNet, is that in our paper, we mainly aimed to compare the connection pattern between DenseNets (dense connection) and ResNets (residual connection),. Note that this tutorial assumes that you have configured Keras to use the TensorFlow backend (instead of Theano). Each dense block consists of convolution layers. In this book, you will find several recently proposed methods in various domains of computer vision. GoogLeNet Info#. The implementation supports both Theano and TensorFlow backends. keras/keras. Architecture. All the given models are available with pre-trained weights with ImageNet image database (www.
