, and a few menus for reporting. As shown in figure: Let's take a look at some of the features of Performance Monitor: Windows Performance Monitor uses performance counters, event trace data, and configuration information that can be merged into a data collector set. Performance counter: A unit of measurement that is a system state or activity condition. They can be included in the operating system or as part of an individual application. Windows Performance Monitor requests the c

In the process of Finereport this report software, it is often necessary to use the function is data analysis. And how the complex data, collation analysis, so as to draw clear findings, it is our learning Finereport the key to this software. The following small series for everyone to share the Finereport report how to data visualization analysis, I hope this tutorial can help everyone! 　1. b/S data source configuration Start the Web server (the FR

From tensorflow.examples.tutorials.mnist import Input_data First you need to download the data set by networking: Mnsit = Input_data.read_data_sets (train_dir= './mnist_data ', one_hot=true) # If there is no mnist_data under the current folder, the folder is created first, Then download the mnist dataset Partition of training set and test set: X_train, Y_train = Mnist.train.images, mnist.train.labels # returns X_train is a multidimensional array under NumPy, (55000, 784) X_test, y_

Turn from: http://www.cnblogs.com/haoyul/p/6910679.html For a long time did not write code, recently took the calculation of triangular mesh surface Gauss curvature practiced practicing, and realized the Gaussian curvature visualization, reviewed a little differential geometry knowledge. Feel sometimes still want to write the code, debugging and running, combined with the test results, in order to have a deeper understanding of the corresponding know

Related library: WINSTON,TK. Features: Pure Julia to build, rare, hehe. Basic functions of back-Test visualization: It is easy to see the date of day trading in each transaction point, the day of each profit and loss situation. Do not go to the market to find and control, that too hard. With this analysis tool, we can greatly improve the efficiency of the analysis of the flow of the back-test transaction. It can be used in front of the pan or back. Yo

What visualization can bring to the team. 1, help XXX project and XXXX Project can coordinate human resources well, ensure the smooth delivery of the project. 2, to help each member of the team to understand the participation of the project and the overall progress. 3, promote team communication and collaboration, and expose problems. The color and function of the note distinguishes yellow notes from the story, in the project bar, to the user delivere

Visual Description In the previous blog hog principle and OPENCV implementation, we explained the principle of hog algorithm. The final feature is a string of vectors, and we don't know exactly what it looks like, or whether it can reflect the difference between the target area and the non-target region. To solve this problem, we need to visualize the hog feature.The Hog feature first calculates the gradient of each pixel, then creates a sliding window, creates a sliding block in the sliding wi
