I really like it. Could you give some examples of applications of it? How one could use the obtained results?

Or maybe if you already done it where can I get it?
Thank you very much

Excellent find David! I think I agree with your fix. I have edited and uploaded the updated workbook.

Thanks for this – very helpful for me learning neural networks and being an old hand at excel!
I think I found some tiny bugs in the formulas.. specifically, cells J5 I think should be multiplying to $F$9 (so that it reads from X2) and similar for Cell J9 this one should be multiplying to $F$4… If I’ve understood correctly in any case.
Going to try and add an extra hidden layer and/or extra nodes in the first hidden layer as bit of practice, hopefully helps me understand it more!
Cheers David

Hello Syed,
Can you also incl. the sigmoid version into the Zip file ? then I can compare two version.

Thanks

Hi Bry – the neuron function is sigmoid, I’ll clarify and upload an edited workbook. Thanks for pointing this out!

Dear Syed,

Thanks for the file and great work. On the activation function it will be great to have a comment to clarify the sigmoid from the tanh
I am new to this so your help is much appreciated.

Dear Syed,

Thanks for the file and great work. On the activation function using Tanh is the equation =1/(1+EXP(-1.72*K4)) correct? This looks like a sigmoid function or is this a modified function.

I am new to this so your help is much appreciated.
