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), so we build our DenseNet models in the same "deep and I am looking at the text generation example using Keras here and I noticed that a Dense(len(chars)) is included as the last layer. regularizers. Keras can also log to TensorBoard easily using the TensorBoard callback. Implementations of VGG16, VGG19, GoogLeNet, Inception-V3, and ResNet50 are included. Busy again. com/sindresorhus/awesome) # Awesome [![Awesome](https://cdn. Introducing Pytorch for fast. You will see a folder named model with several files inside. Input. Keras Applications are deep learning models that are made available alongside pre-trained weights. When compared to TensorFlow, Keras API might look less daunting and easier to work such as DenseNet, make sure to set the learning phase to 0 before loading the Keras model in a new session. We present a residual learning framework to ease the training of networks that are substantially deeper than those used For example, TensorFlow has a great community, PyTorch is an excellent framework to easily develop models in a short time and also it provides a fantastic C++ API for production level tasks, MXNet is a great framework for extremely large-scale training (i.
