[plugin] rex_ANN (Artificial Neural Network)

Document, plugin and sample capx included.

The sample capx is training the ANN to recognize the boolean XOR logic.

Hmm, first time I hear about it. What kind of usability this could be for?

megatronx

I though it could be used at AI, but I had not used for that yet. Just port the library into C2 plugin.

is the sample file correct? All it has is 3 objects (ANN, Browser and Functions), but the Event Sheet is completely empty (and so is also the layout).

Ubivis

It is correct. The sample capx is try to train the ANN to be a "XOR gate". The output messages are log at console of browser.

There's definitely something wrong with the capx.

The event sheet showed 0 events like Ubivis reported, but the preview is still logging messages to the console like you said.

At first I thought it was some kind of hard-wired behavior, but after some time adding events (in the previously empty event sheet) a lot of events popped out of nowhere.

I guess the capx is corrupted somehow.

Also the action to set the learning rate and momentum factor is wrongly named as a duplicated "Define hidden node count".

I would like to suggest an action to define/add inputs in the same way as inputs are set, so they could be dynamically defined through expressions. This would allow to run a loop to define all inputs, which would be extremely useful when using an array as input for a feature detection NN for instance. Something in the line of:

 Define new input str( loopindex("x")&loopindex("y") )[/code:1jmtvu2q]
Currently it's impractical to define all inputs manually through the "Add parameter" button, since a small 10x5 array would need 50 inputs to be defined by hand.

Update

• Re-save the capx to r175 version
• Add 2 actions "Action:Define inputs by dictionary", "Action:Define outputs by dictionary". User could create the name of inputs/outputs into a dictionary first by events dynamically, sample capx

Thanks for these suggestions. Hope these 2 actions could have more flexible for assigning inputs/outputs.

Hi Rex,

Very nice plugin. May I ask, if the output could be trained other than binary (~0 & ~1), like 100?

I've tried to modify XOR, but the output is not correct, and comes to ~0.9999 in all cases..

0,0 ->0

0,1 -> 100

1,0 -> 100

1,1 ->0

many thanks,

Zs

In plugin, it is better control the output to 0~1.

Can this be used for gesture recognition training?

I don't know, the input and output data of real application needs some pre-processing and post-processing which does not include int this plugin.

Will somebody please post a working sample file.

Is there any ways to get/set the weights to do some kind of genetic algorithm ?

Sirvoid

Sorry, it is not in my plan.

I would like improve this plugin, but I don't have time.

rexrainbow This is very interesting, still trying to figure out how this works. I understand that all the information is being shown in the Chrome Console, and I think that it learns from whatever is being shown on the canvas but I’m not entirely shown. I’m trying to use this to make an AI Chatbot.

Edit: Possibly an updated version of this and a quick explanation of how it works would be nice
