你好我更新了以下功能:如何解決以下錯誤建立一個神經網絡?
def train(self, features, targets):
的想法是讓我的待辦事項在線課程我嘗試這樣做:
# TODO: Output error - Replace this value with your calculations.
error = y - final_outputs # Output layer error is the difference between desired target and actual output.
# TODO: Backpropagated error terms - Replace these values with your calculations.
output_error_term = error * final_outputs * (1 - final_outputs)
# TODO: Calculate the hidden layer's contribution to the error
hidden_error = np.dot(output_error_term, self.weights_hidden_to_output)
# TODO: Backpropagated error terms - Replace these values with your calculations.
hidden_error_term = hidden_error * hidden_outputs * (1 - hidden_outputs)
但是我:

這是完整的代碼,我下載我的IPython的筆記本,以顯示我的完整代碼:

我真的很感謝支持來克服這個問題非常感謝支持。
