Hi
It's not clear to me: hereby the extract from the example published here:
https://code.google.com/p/neurolab/
>>>
# Create network with 2 inputs, 5 neurons in input layer and 1 in output layer
>>>
net
=
nl
.
net
.
newff
([[-
0.5
,
0.5
],
[-
0.5
,
0.5
]],
[
5
,
1
])
Two questions:
It seems 5 neurons in the hidden layer?
len(net.layers) gives '2'. it means 'newff' doesn;t count input layer?
Thanks for help,
Maxim

Hi,
This is just a guess.
The input layer connects to layer 0 so it doesn't need any inputs or outputs so it can ignored as a seperate layer.
Look at the example on modifying the weights and biases and look at the Layer class. You'll see the inputs represented in the data.
net
.
layers
[
0
]
.
np
[
'w'
] should have an array of a shape (2,5) i.e. 2 inputs connected to 5 nodes.

Не понял, а что вы ожидали получить
>>> len(net.layers)
от 2х слойной сети?

Евгений,
получается в вашей реализации входной слой = скрытый слой? Это мне и было непонятно. Спасибо за разъяснение.
