What is the main idea behind Hebbian Learning?

Strengthening synapses that are used more

What is a key characteristic of the Perceptron model of decision making?

Making decisions based on the weighted sum of inputs

In Machine Learning, how are synaptic strengths (weights) determined?

By finding optimal weights consistent with the given data

What is the purpose of training a perceptron?

To find the optimal weights that minimize error

How does a perceptron change its output as weights are adjusted?

The output adjusts based on errors minimized by weight changes
