Python sigmoid Examples

Example #1

File: net.py Project: anskaal/NeuralNet

def fx(func, i, nodes, debug):
  if func is "sigm":
    res = nnlib.sigmoid(nodes[i])
  elif func is "tanh":
    res = nnlib.hyper_tan(nodes[i])

  log.d(debug, log.hl("f(%d)  \t(%.2f)\t---> %s \t--->   (%.2f) " %(i, nodes[i], func, res),2))
  nodes[i] = res

Example #2

File: test_nnlib.py Project: anskaal/NeuralNet

def test_sigmoid():
    assert nnlib.sigmoid(-1) > 0
    assert nnlib.sigmoid(0) == 0.5
    assert nnlib.sigmoid(1) < 1
