Artificial Neural Network modeling using Matlab (Deep learning toolbox, neural net fitting)

The video shows the implementation of artificial neural network for modeling and predicting the experimental data.

Superb explanation.

[@kiranhm2336]

I have one doubt how to get weight and bias values and also how to create equation from the model, can you please explain me

[@adityakumar186]

​@@kiranhm2336you cannot generate equations, only an objective function is generated as shown in the last part. This objective function works similar to equations. For changing weight and bias, for weight and bias change, code can be written.

This is the best tutorial on NN tool using MATLAB. thanks!!

[@HungNguyen-dd8mc]

Sir, I did not see the output in variables after exporting the result of Neural Net Fitting as Export to Workspace. How can I fix it? I use Matlab2024. Thank you.

[@adityakumar186]

1. Make sure your folder with the .m file is open in matlab, 2. Function name is same as .m file name. 3. Input function format is the same as predictors, "ans" variable will appear if everything is correct.

[@HungNguyen-dd8mc]

@@adityakumar186 I typed function as you mean. But It shows: "Did you mean: >> example(Pred) Unrecognized function or variable 'Pred'. I am sure that I finished the 1st and 2nd steps as you mean.

[@soft_problems6196]

@@HungNguyen-dd8mc Unrecognized function is more likely due to the (1.) check the left side of the screen (in video) folder should be open and should contains ANNyt1.m. If the input variable is unrecognised check the screen on right hand side (variable: Pred) "check for the matrix transpose".

sir in MATLAB R2023a where can see the value of weight and bias and how to change active function

[@adityakumar186]

I have shown the use of a deep learning toolbox for modeling. For weight and bias change you should see matlab code. I have not used matlab code.

[@vengateshharthim7887]

bro in the MATLAB R2021 version, I can see the ANN weights and bias in network TAB but in version 2023 I could not see the option @@adityakumar186

[@wilfriedbekono3929]

I actually have more than 2 parameters. I carried out basic statistical analyses on the data to obtain the major elements influencing the data set but i can't obtain the prediction equation of CBR prediction(an equation of degree two with some paramètres expressed in exponential

[@soft_problems6196]

ANN will not give results in the form of an equation (complex code). To get equations (quadratic or cubic) regression analysis is better. ANN has improved prediction accuracy, its model function can be used as an equation.

Sir from where we can adjust number of jidden layers in R2021a?

[@adityakumar186]

The number of layers is fixed (1 hidden), which is sufficient for simple problems. Only layer size can be changed in the neural net fitting app.

[@esmailhossaineshak658]

Which version of matlab??

[@soft_problems6196]

@@esmailhossaineshak658 2024a Version does not matter, You have to download neural net fitting app in Matlab
