Tensorflow creates variables and searches for variables by name. tensorflow Variables Environment: Ubuntu14.04, tensorflow = 1.4 (bazel source code installation), Anaconda python = 3.6 There are two main methods to declare variables:Tf. VariableAndTf. get_variable, The biggest difference between the two is: (1) tf. Variable is a class with many attribute function

Comparison between Caffe, TensorFlow, and MXnet open source libraries Recently, Google opened up its internal deep learning framework TensorFlow [1] and discussed the three open-source libraries in combination with the open-source MXNet [2] and Caffe [3, among them, only Caffe has carefully read the source code. The other two libraries only read the official documentation and some comments from researchers.

Mnist is an entry-level computer-vision dataset that contains 60,000 training data and 10,000 test data. Each sample is a variety of handwritten digital pictures below: It also contains the corresponding label for each picture, telling us this is a number. For example, the above four pictures are labeled 5,0,4,1. Mnist's official website: http://yann.lecun.com/exdb/mnist/ You can view the current maximum record for the project: http://rodrigob.github.io/are_we_there_yet/build/classification_dat

TensorFlow is used for simple linear regression and gradient descent examples. tensorflow gradient Linear regression is supervised learning. Therefore, the method and supervised learning should be the same. First, a training set is given and a linear function is learned based on the training set, then, test whether the function is trained (that is, whether the function is sufficient to fit the training set

1. Overview As with the old version of TensorFlow, the model needs to be saved, and this preservation is cyclical. Because in many cases the gradient will swing around the local minimum, that is to say, in many cases, the last training model is not necessarily optimal. 2. Save the Model We can create a location where the checkpoint is saved when we build the model, and we can start by creating a folder with the following command. You can add paramet

for a 3D object and use reverse propagation for optimization during rendering. Since 3D objects have more freedom than images, we typically use random parameterization, which generates images that are rendered from different perspectives.In the next section of the article, we'll give a few examples to prove the effectiveness of using the above methods, which bring surprising and interesting visual results.Visual interpretation of Alignment featuresRelated Colab page: https://colab.research.goog

1. Overview A feature column is a bridge between the original data and the model. In general, the essence of artificial intelligence is to do weights and offset operations to determine the shape of the model. Before using the TensorFlow version, the data must be processed in a kind and distributed way before it can be used by the artificial intelligence model. The appearance of feature columns makes the work of data processing much easier. 2, the fun

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 curve.

In general, there are two functions for printing tensorflow variables:tf.trainable_variables () and Tf.all_variables ()The difference is:Tf.trainable_variables () refers to the variables that need to be trainedTf.all_variables () refers to all variables In general, we are more concerned with training variables that need to be trained:It is important to note that the entire graph is initialized when the variable name is output First, print the name of
