It is better to have a comparison of these lasagne,keras,pylearn2,nolearn, tensor and symbolic calculation framework I have chosen to use Theano, the top of the library with which good? First of all, the document is as detailed as possible, its secondary structure is clear, the inheritance and the invocation is convenient. Reply content:Python-based libraries personal favorite is the Keras, for a variety of

Let's spit it out. This is based on the Theano Keras how difficult to install, anyway, I am under Windows toss to not, so I installed a dual system. This just feel the powerful Linux system at the beginning, no wonder big companies are using this to do development, sister, who knows ah ....Let's start by introducing the framework: We all know the depth of the neural network, Python started with Theano this framework to write the neural network, but la

Deep learning Keras Frame Notes Autoencoder class use notes　　This is a very common auto-coding model for building.

In Keras, a neural network visualization function plot is provided, and the visualization results can be saved locally. Plot use is as follows: From Keras.utils.visualize_util import plot plot (model, to_file= ' model.png ') Note: The author uses the Keras version is 1.0.6, if is python3.5 From keras.utils import plot_model plot_model (model,to_file= ' model.png ') However, this feature relies on the

Recently paid attention to a burst of keras, feeling this thing quite convenient, today tried to find it really quite convenient. Not only provide the commonly used algorithms such as layers, normalization, regularation, activation, but also include several commonly used databases such as cifar-10 and mnist, etc. The following code is Keras HelloWorld bar. Mnist handwritten digit recognition with MLP implem

Deeplearning library is quite a lot of, now GitHub on the most hot should be caffe. However, I personally think that the Caffe package is too dead, many things are packaged into a library, to learn the principle, or to see the Theano version.My personal use of the library is recommended by Friends Keras, is based on Theano, the advantage is easy to use, can be developed quickly.Network frameworkThe network framework references Caffe's CIFAR-10 framew

This weekend, I decided it is time:i is going to update my Python environment and get Keras and TensorFlow installed So I could the start doing tutorials (particularly for deep learning) using R. Although I used to is a systems administrator (about years ago), I don ' t do much installing or configuring so I guess T Hat ' s why I ' ve put the this task off for so long. And it wasn ' t unwarranted:it took me the whole weekend to get the install working

In recent months in order to write a small paper, the topic is about using the depth of learning face search, so you need to choose a suitable depth learning framework, Caffe I learned after the use of the feeling is not very convenient, after someone recommended to me Keras, its simple style attracted me, After four months I have been using the Keras framework, because I use the time, the TensorFlow tutori
