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
