I dedicate this work to the my son "Loukmane BERGHOUT".

Extreme Learning Machine ELM is the new dominate training tool for trainig a single hidden layer feed-forward neural network.
the basic learning rules of ELM is presented In these codes.

Important characteristics of this version:
- It extended for usage for both classification and regression.
- It contains functions that normalize the input samples between any desired values.
For classification:
- It allows encoding of the labels of classes into binary codes to satisfy the constraints of Activation functions boundaries.
- After training and in case of prediction the algorithm has the capability to decode again those codes into original labels.
For regression:
- The algorithm also can renormalize the output values after training into original interval.

For any information concerning this code contact me via : berghouttarek@gmail.com

How to plot confusion matrix for ELM? Please include in code

xudong liu

Thank you very much

Warwick

Not anywhere I can find. I tried downloading your toolbox for Deep Learning too, but not there.
Maybe just doen't like my Mac and R2019a. Thanks anyway.

the 'cancer dataset' is already included in matlab, just run the example.

Warwick

Hi. Where is 'cancer_dataset'? Could you include it the zipped files?

Luo

The prog is not well tested. The Bias Matrix is missing. Therefore the result is misleading.

Hello,

The size of
TrainingData: 200 x 13
Training Target : 200 x 1
Test Data : 80 x 13
Test Target: 80 x 1
in the elm_train.m file, while calculating the beta:
I have this error being shown - "Inner matrix dimensions do not agree"

could you please help me on this.

Thanks,
Rahul
