Introduction
TensorFlow 1.0.0, a new SEQ2SEQ interface was developed and the original interface was deprecated.
The old Seq2seq interface is the part under Tf.contrib.legacy_seq2seq, and the new interface is under TF.CONTRIB.SEQ2SEQ.
The main difference between the new SEQ2SEQ interface and the old one is that it is dynamically expanded , while the old one is st
Time series prediction can be based on short-term forecasts, long-term forecasts and specific scenarios, such as Arma, ARIMA, neural network prediction, SVM prediction, grey prediction, fuzzy prediction, combined forecasting method and so on. The so-called no best model, only the most suitable model. As to which model can achieve the highest precision for a particular predictive problem, it needs to be proved by experiments. In this paper, a single Variable time series prediction experiment is c
The best way to learn TensorFlow is to read the official document: https://www.tensorflow.org/versions/r0.12/tutorials/seq2seq/
First, TensorFlow of the RNN use:
1. Using lstm
Lstm = Rnn_cell. Basiclstmcell (Lstm_size)# Initial State of the LSTM memory.state = Tf.zeros ([Batch_size, Lstm.state_size])probabilities = []Loss = 0.0For Current_batch_of_words in Words_in_dataset:# The value of state was updated after processing each batch of words.Output,
prediction, but also can be used for video classification, video frame tag.
Seq2seq
In the two models of many to many, the above figure can see that the fourth and fifth are different, the classical RNN structure of the input and output sequence must be equal length, its application scenario is relatively limited. And the fourth kind of it can be the input and output sequence is not long, this model is the SEQ2SE
Install first and say:
sudo pip install Keras
or manually installed:
Download: Git clone git://github.com/fchollet/keras.git
Upload it to the appropriate machine.
Install: CD to the Keras folder and run the Install command:
sudo python setup.py install

Keras provides many common, prepared layer objects, such as the common convolution layer, the pool layer, and so on, which we can call directly through the following code:
# Call a conv2d layer
from Keras import layers
conv2d = Keras.layers.convolutional.Conv2D (filters,\ kernel_size
, \
strides= (1, 1), \
padding= ' valid ', \
...)
However, in practical applications, we often need to build some layer obje
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

We strongly recommend that you pick either Keras or Pytorch. These is powerful tools that is enjoyable to learn and experiment with. We know them both from the teacher ' s and the student ' s perspective. Piotr have delivered corporate workshops on both, while Rafa? is currently learning them.

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
