Questions and Answers

What is the main idea behind Hebbian Learning?

  • Strengthening synapses that are used more (correct)
  • Randomly adjusting synaptic strengths
  • Strengthening synapses that are not used
  • Weakening synapses that are not used
  • What is a key characteristic of the Perceptron model of decision making?

  • Utilizing fuzzy logic to make decisions
  • Making decisions based on the weighted sum of inputs (correct)
  • Weights that are not adjusted during learning
  • Multiple thresholds for different inputs
  • In Machine Learning, how are synaptic strengths (weights) determined?

  • By finding optimal weights consistent with the given data (correct)
  • By randomly assigning weights initially
  • By keeping weights fixed throughout the learning process
  • By weakening all synapses to start afresh
