calculate gradients and update weight coefficients; Remember to perform optimizer output.
Use a predefined common loss function:
Initializes using Xavier, and Tf.layer automatically sets the weighting factor (weight) and the offset (bias).
C. Senior Wrapper--keras
Keras can be understood as a layer at the top of the TensorFlow, which can make some work simpler (and also support Theano backend).

Keras is also a library of Python deep learning programs, but it leverages TensorFlow and Theano, which means

2.7 and 3.5 Two versions of Python were installed on the notebook, and failed to create process error occurred while installing Keras with the 3.5 version of PIP. Here's how to fix it:1. Since I have configured both 2.7 and 3.5 paths in the environment variable, I can execute python3 directly at the command line to start the 3.5 version of Python;2. Start the PIP via Python3, enter the python3-m pip install Keras
When I used the Keras visualization model, I met the above error with the following error message:
Traceback (most recent):
File "harrison_feature_model.py", line The solution is:
Pip install pydot-ng
pip install GraphvizAnd then it's solved, my system for Ubuntu 16.04
Or:
sudo pip3 install pydot
sudo pip3 install graphviz sudo apt-get install Graphviz
The solution below is also Ubuntu 16.04, but it's Python3

November 9, 2015 Google Open source of the artificial intelligence platform TensorFlow, but also become the 2015 's most popular open source projects. After 12 iterations from v0.1 to v0.12, Google released its version of TensorFlow 1.0 on February 15, 2017, and hosted the first TensorFlow Dev Summit conference in Mountain View, California, USA. TensorFlow 1.0 and Dev Summit (2017) Review
Compared with previous versions, the features of TensorFlow 1.0 are mainly reflected in the following aspect

Two key issues:
1. Why has the memory function.
This is the problem solved in the RNN, because there is a recursive effect, the state of the hidden layer at the moment to participate in the calculation of this moment, the explicit point of the statement is the selection and decision-making reference to the last state.
2. Why lstm remember the long time.
Because the specially designed structure has the characteristics of CEC, error up a last state when
, there are many mature Data Mining methodologies in the industry, providing an ideal guidance model for practical applications. Among them, there are three main standardization: CRISP-DM; pmml; Ole DB for DM. CRISP-DM (Cross-Industry Standard Process for da Ta Mining) is one of the currently recognized and influential methodologies. CRISP-DM emphasizes that DM is not only a data organization or presentation, but also a data analysis and statistic
classification tasks and data mining. it is alsoavailable as a product within information builders 'business intelligence suiteknown as rstat.
The aim is toprovide a simple and intuitive interface that allows a user to quickly loaddata from a CSV file (or via ODBC), transform and perform e the data, build andevaluate models, and export models as pmml (predictive modelling markuplanguage) or as scores.
All of this withknowing little about R. all r com
. We should use a multi-parameter and not less-than-fit network model. The tradeoff between too much capacity and too little capacity.Unfortunately, there is no effective rule or method to determine the size of the model parameters. You must constantly try to find the optimal parameter size on the validation set. a general approach to determining the size of a model: start with a relatively simple model, gradually increase or decrease the number of neurons or the number of network layers until t
