Re: [Pharo-users] Neural Networks in Pharo

And I have added a PolyMath dependency to the configuration file, so now the Metacello script should update you to the latest stable versions of everything automatically. Thanks for pointing it out. On Fri, Apr 28, 2017 at 11:05 PM, francescoagati [via Smalltalk] < ml+s1294792n4944863...@n4.nabble

Hello, I have finally added a configuration to the NeuralNetwork project. Now you can use this Metacello script to load it into your Pharo image: Metacello new repository: 'http://smalltalkhub.com/mc/Oleks/NeuralNetwork/main'; configuration: 'MLNeuralNetwork'; version: #development; load.

Hi Oleks, there is a mode for install neural network from metacello? 2017-04-25 13:00 GMT+02:00 Alexandre Bergel : > Continue to push that topic Oleks. You are on the right track! > > Alexandre > > > On Apr 24, 2017, at 1:43 AM, Oleks wrote: > > > > Hello, > > > > Thanks a lot for your advice! I

Re: [Pharo-users] Neural Networks in Pharo

Hello, Thanks a lot for your advice! It was very helpful and educating (for example, I thought that we store biases in the weight matrix and prepend 1 to input to make it faster, but now I see why it's actually slower that way). I've implemented a multi-layer neural network as a linked list of la

Re: [Pharo-users] Neural Networks in Pharo

I definitely agree with this. Performance-wise, I expect it to be terrible to model each individual neuron as an object. The logical unit (IMHO) should be a layer of neurons, with matrix weights, vector biases, and vector output. Similarly, I think you'd be better off keeping the bias as a separat

--- Begin Message --- Hi Oleksandr, Since you are interested in the implementation aspect of neural networks, may be you should take a look on heuristiclab (http://dev.heuristiclab.com/trac.fcgi/wiki); a general framework for developing heuristic algorithms (not only neural networks, actually)

Re: [Pharo-users] Neural Networks in Pharo

Nice to see this development. On the examples issues suggested by Alexandre, maybe Grafoscopio[1] could be useful to combine prose with code. I have write a new user manual [2] and I'm going to work on it this summer of code. [1] http://mutabit.com/grafoscopio/index.en.html [2] http://mutabit

Re: [Pharo-users] Neural Networks in Pharo

Hi Oleksandr! I had a look at your code a couple of weeks ago, as I also got some interest in Neural networks and genetic algorithm (I will start a lecture here at my university on this topic). I think that your code needs examples. Maybe you can add some simple examples, such as learning bool

Re: [Pharo-users] Neural Networks in Pharo

Hi Oleksandr, I'm working half-time on a team doing simulations of spiking neural networks (on scala). Since the topic is "new" to me, I started following a MOOC on traditional machine learning and putting some of my code in here: https://github.com/guillep/neural-experiments Also, I wanted to e

Re: [Pharo-users] Neural Networks in Pharo

I started by implementing some simple threshold neurons. The current goal is a multilayer perceptron (similar to the one in scikit-learn), and maybe other kinds of networks, such as self-organizing maps or radial basis networks. I could try to implement a deep learning algorithm, but the big issue
