In the context of convolutional neural networks (CNNs), what is the primary purpose of pooling layers?

  • Pooling layers are used to reduce the spatial dimensions of the input volume for subsequent layers.
  • They increase the depth of the network which leads to an increase in the computational complexity.
  • Pooling layers serve to convolve the input image with a filter to extract features.
  • The main purpose of pooling layers is to introduce non-linear activation functions.
  • They flatten the input features into a one-dimensional array suitable for the fully connected layers.

Considering the recent advancements in deep learning, which of the following techniques allows for the efficient training of deep neural networks by normalizing the inputs in each mini-batch?

  • Dropout
  • Batch Normalization
  • Gradient Clipping
  • Early Stopping
  • Transfer Learning

What does the term 'perplexity' refer to in the context of evaluating language models in deep learning?

  • The number of model parameters
  • The estimated average code length per symbol
  • The measure of how well a probability model predicts a sample
  • The depth of a neural network
  • The variance in feature importance

In the table provided, which activation function's derivative remains constant for nonzero inputs?

  • ReLu
  • Sigmoid
  • Tanh
  • Softmax

What is the impact of using Rectified Linear Unit (ReLU) activation functions in deep learning models compared to Sigmoid functions?

  • ReLU functions can accelerate the convergence of stochastic gradient descent compared to Sigmoid due to the non-saturation of its positive part.
  • ReLU functions are less computationally efficient than Sigmoid functions due to their non-linearity.
  • The use of ReLU functions significantly increases the likelihood of vanishing gradient problems.
  • Sigmoid functions are preferred in deep layers of a neural network due to their ability to output non-zero centered results.
  • ReLU functions cannot represent negative input values, making them less suitable for certain types of data.

How does batch normalization aid in training deep networks?

  • It helps in reducing the internal covariate shift by standardizing the inputs of each layer.
  • Batch normalization eliminates the need for any non-linearity like ReLU in neural networks.
  • It increases the model's bias, hence making it less prone to overfitting on training data.
  • It reduces the computational load by allowing the use of smaller mini-batch sizes.
  • Batch normalization helps in completely avoiding the vanishing gradient problem in very deep networks.
