This article introduces the relevant knowledge of "how to build a neural network through nntool". In the operation of actual cases, many people will encounter such a dilemma. Next, let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

The full name of nntool is neural network / data management tool. Compared with other tools such as neural network fitting tool and neural network pattern recognition tool, neural network tool (nntool) is more comprehensive and flexible, and can choose the type of neural network and train it.

Enter nntool in the command line window and press enter to open the Neural Network/Data Manager window

Click New... Button, select the Data tab, enter the variable name P, select the variable type Inputs, and enter the variable value

Click the Create button to complete the creation, and you can also create the target data T

Click New... Button, select the Network tab, enter the network name, select the network type, and specify the input data and target data to complete the creation

Click Open... Button, select the corresponding tab pole course in the pop-up Network dialog box to carry out the corresponding operation, because the radial basis network is selected and can be used once created, disorderly training, so directly select the Simulate tab, select the input sample variable P in the Inputs drop-down box, because P is also a training sample, you can observe the error of the network. Check the Supply Targets check box, select the target vector T, and then click the Simulate Network button to conduct the simulation test. You can make variable names for output variables and error variables on the right side of the window.

Select a variable in the nntool window and click Open... Button to view the variable value

You can also click Export... Button to export variables to workspace

Select the network in nntool and click Open... The pop-up dialog box has multiple tabs, in addition to viewing the network model, training the network, and simulation testing.

You can also view or modify network weights and thresholds in the View/Edit weight tab

In this way, the creation, training and testing of the neural network model are completed.

This is the end of the content of "how to build a neural network through nntool". Thank you for reading. If you want to know more about the industry, you can follow the website, the editor will output more high-quality practical articles for you!
