Questions and Answers

What operation is simply called convolution in the context of neural networks?

  • Applying filters to image patches (correct)
  • Uniformly connecting pixels in an image
  • Summation of all pixels in a patch
  • Shifting patches across the image
  • How is the spatial structure incorporated into neural networks?

  • By randomly selecting input pixels for connections
  • By connecting patches of the input to a single neuron in the hidden layer (correct)
  • By connecting every single input pixel to a neuron in the hidden layer
  • By ignoring the spatial structure altogether
  • How are visual features learned in the context of the text?

  • By directly applying filters to the entire image
  • By uniformly connecting pixels to the hidden layer (correct)
  • By shifting filters across the image randomly
  • By ignoring spatial information in the image
  • What is the drawback of connecting every input pixel to a single neuron in the hidden layer?
