Tensorflows

Q 1: Hidden layer must use activation function with larger derivative.

  • A True
  • B False

Q 2: If a shallow neural network has five hidden neurons with three input features, what would be the dimension of weight matrix of hidden layer?

  • A (3,3)
  • B (5,3)
  • C (5,5)
  • D (3,5)

Q 3: You are building a binary classifier for classifying output(y=1) vs. output(y=0). Which one of these activation functions would you recommend using for the output layer?

  • A sigmoid
  • B leaky-relu
  • C relu
  • D tanh

Q 4: sigmoid_cross_entropy() function of tensorflow internally performs sigmoid activation for the final layer output.

  • A True
  • B False

Q 5: Input data is passed through placeholders in TensorFlow.

  • A False
  • B True

Q 6: Tensorflows GradientDescentOptimizer() function tries to maximize the cost while training the network.

  • A True
  • B False
