Question #1

Open Nivekiba opened 5 years ago

Nivekiba commented 5 years ago

Hello EiiSolver, me too i'm on codingame. For some contest i wanna use neural network (keras also) but i don't knew how to import the training results in CG. So my question is how do you do that ? Thanks a lot for reading. I'm waiting for your response

Hi, I use the following function to generate (horrible) C++ code containing the model's weights: def output_layers(file, model, function_name): i = 0 file.write('#include "ff_net.h"\n') file.write('void %s(FFNet &net) {\n' % (function_name)) for layer in model.layers: i = i + 1 weights = layer.getweights()[0] for j in range(0, len(weights)): file.write('static double w%d%d[] = ' % (i, j)) printarray(file, weights[j]) file.write('net.layers[%d].weights = {' % (i)) for j in range(0, len(weights)): file.write('w%d%d, ' % (i, j)) file.write('};\n') file.write('net.layers[%d].bias = ' % (i)) print_array(file, layer.get_weights()[1]) file.write('}\n')

where model is a keras model (models.Sequential, only dense layers are supported by my export function); my LOCM model is:

model = models.Sequential()
model.add(layers.Dense(30, activation='relu', input_shape=inp_shape,

use_bias=True)) model.add(layers.Dense(1, activation='sigmoid'))

FFNet is a home-written C++ class that can perform feed-forward calculation for the neural network.

Good luck!

ah..ok so <ff_net,h> is present in c++ librairies in CG ??

eiisolver commented 5 years ago

No, you have to write an implementation yourself... I have a home written tool that allows me to write code in multiple source files and from those files creates one cpp file that can be copied to CG.

you implement ff_net.h your self ? That's not too much work ?
