Keras Introductory Lesson 5: Network Visualization and training monitoring
This section focuses on the visualization of neural networks in Keras, including the visualization of network structures and how to use Tensorboard to monitor the training process.Here we borrow the code from lesson 2nd for examples and explanations.
The definition of the front of the net
Tensorboard is an official visualization tool provided by TensorFlow. The data in the model training can be summarized and displayed. This article is based on the tensorflow1.2 version. This version of the Tensorboard interface is shown in figure:Image.png
The Tensorboard supports 8 visualizations, which are the 8 tabs in the figure above, namely: scalars: Scalar

A simple explanation: Tensorboard is a visual tool that can be used to view TensorFlow diagrams and various values and images in the process.1. Add "Summary operations" to the desired node in the TensorFlow program, and "Summary operations" collects the n

Tensorboard:tensorflow comes with a visual tool. The chart visualization with Tensorboard encountered a problem that the chart does not display.Environment: Ubuntu systemRun the code to get the TensorFlow event file logs, for example the path is:/home/wang/tensorflow/logs, logs also contains train and test. At this point, Tensorboard runs by reading the event file by typing the command in cmd:

Tensorboard and TensorFlow programs run in different processes , Tensorboard automatically reads the latest TensorFlow log files , and renders the current TensorFlow program running in the latest state. 2, Tensorboard use process to ad

When you want to see the distribution of values for a tensor during the training process, the statistics for their distribution can be displayed in the Tensorboard page by using the following statement:

(1) Use Tensorboard under Ubuntu as described on the official website.

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
The Tensorboard histogram dashboard shows how the distribution of some tensor in the TensorFlow graph changes over time. It is visualized by displaying many histograms of tensor at different points in time.
One, see a basic example
A normally-distributed variable, a normal distribution value. The mean changes over time.We use the tf.random_normal operation directly. Perfect solution.Of course, you also use the ten
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 in Theano, before learning Keras, first understood th
Typically, we add summary when we train the network by using the following methods:
Tf.scalar_summary (tags, values)
#
... Summary_op = Tf.summary.merge_all ()
summary_writer = Tf.summary.FileWriter (LogDir, graph=sess.graph)
Summary_str = Sess.run (summary_op)
summary_writer.add_summary (Summary_str, Global_step)
When we want to add other data to the Tensorboard (such as the validation of the loss, etc.), this approach is too cumbersome, in fact, we
Personally feel tensorflow relative to other in-depth learning Coulai said is relatively good installation, I began to install Theano had not been installed for several days, and finally have no way to install the TensorFlow, even a little problem is not out, one-time installation is good, Chong This I also optimistic tensorflow. TensorFlow support the Windows system, but the Python version to Python3 above, Python3 and Python2 still have quite a lot of difference, use the time to pay attention
