Keras is a python library for deep learning that contains efficient numerical libraries Theano and TensorFlow.
The purpose of this article is to learn how to load data from CSV and make it available for keras use, how to model the data of multi-class classification using neural network, and how to use Scikit-learn to evaluate Keras neural network models.Preface,
It is best to compare lasagne, keras, pylearn2, and nolearn. I have already selected theano for tensor and symbolic computing frameworks. Which of the above databases is better? First, the document should be as detailed as possible. Second, the architecture should be clear, and the Inheritance and call should be convenient. It is best to compare lasagne, keras, pylearn2, and nolearn. I have already selected

First, Pytorch introduction
1, the descriptionPytorch is Torch in Python (Torch is a neural network using the Lua language) and TensorFlow comparison Pytorch established neural network is dynamic TensorFlow is a highly industrial of static graph TensorFlow , its underlying code is hard to read. Pytorch good so a little, if you dive into the API, you can at least
First, you need to familiarize yourself with how to use pytorch to implement a feed-forward neural network. To facilitate understanding, we only use a feed-forward neural network with only one hidden layer as an example:
The source code and comments of a feed-forward neural network are as follows: This is relatively simple and we will not discuss it here.

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.

First, Keras introduction
Keras is a high-level neural network API written in Python that can be run TensorFlow, CNTK, or Theano as a backend. Keras's development focus is on support for fast experimentation. The key to doing research is to be able to convert your ideas into experimental results with minimal delay.

Current Computer Configuration: Ubuntu 16.04 + GTX1080 GraphicsConfiguring a deep learning environment, using Tsinghua Source to install a Miniconda environment is a very good choice. In particular, today found Conda install-c Menpo opencv3 A command can be smoothly installed on the OPENCV, before their own time also encountered a lot of errors. Conda installation of the TensorFlow and pytorch two kinds of framework is also very convenient, for not go
Installing OPENCV on the server encountered a problem with CUDA8.0, and had to see if other machines could be preinstalled and used..First, python+opencv3.2 installationOpenCV Why is it so easy to install in Windows?Installation process:1.

Have to say, the depth of learning framework update too fast, especially to the Keras2.0 version, fast to Keras Chinese version is a lot of wrong, fast to the official document also has the old did not update, the anterior pit too much.To the dispatch, there have been THEANO/TENSORFLOW/CNTK support Keras, although said TensorFlow a lot of momentum, but I think the next

Mseloss loss function is called in Chinese. The formula is as follows:
Here, the loss, X, and y dimensions are the same. They can be vectors or matrices, and I is a subscript.
Many loss functions have two Boolean parameters: size_average and reduce. Generally, the loss function directly calculates the batch data. Therefore, the returned loss result is a vector with the dimension (batch_size.
The general format is as follows:
loss_fn = torch.nn.MSELoss(reduce=True, size_average=True)
