Liquid State Machine Set Up #44

Open arccoxx opened 9 years ago

arccoxx commented 9 years ago

Hi,

This is a fantastic project! Good work! I was just wondering whether anyone had any thoughts on how to set up liquid state machines and specifically how they work in this module. I understand they are not the focus. Specifically, I was wondering whether there are anyways to determine pool size, connections and gates. I am finding it hard to dig up some (easily digestable) info on these networks.

Any thoughts?

Thanks!

Hi, its quite simple, as all neural networks LSM works by magic. A special kind of. You take a bunch of neurons, connect each other randomly, pick a few whos act as input, another ones will act as output. and pum! it works. Maybe you can take a look for the architect's src Liquid.ts in the brach 'typescript'. We use layers, but standalone neurons sould work too.

Thanks for the speedy response!

I was concerned more on how to decide the number of pool neurons, connections and gates when building the network. How do I decide on these parameters? Also, is the network self optimizing?

thanks!

Oh hold on I see what the confusion is. I'm interested in the actual design of liquid state networks not how I create them with the module. Specifically based on input output how do I determine the number of neuron gates and connections?

Hope that clears things up.

That's the tricky part, determining the topology of the network (specially with liquid state machines) sometimes can be a matter of trial and error, some approaches use genetic algorithms to find most efficient configurations: create a set of networks with random amounts of neurons/connections, test them solving your problem, keep the ones that do the best job, create a new set of networks using similar configurations (crossover) and repeat the process till you find the topology that suits your problem.

Sorry! brother @menduz which programming language did you used for LSM code
