Reinforcement Learning and Deep RL Python Theory and Projects - Perceptron Exercise Solution

The video tutorial explains how to compute a sum using given variables XI and WI, where XI equals I and WI equals 1/I. The sum is calculated from I equals 1 to N, with examples showing how terms cancel out, leaving N as the result. The tutorial also covers the step function, which outputs 1 if N is 10 or more, indicating the neuron fires. The perceptron model is discussed, emphasizing the need for at least 10 features for the neuron to fire.

What is the value of WI when XI equals 3?

• 1/3

• 3

• 2

• 1/2

What happens to the sum when you perform cancellations in the given series?

• It becomes zero

• It equals the number of terms, N

• It becomes negative

• It doubles

Under what condition does the step function output a 1?

• When N is equal to 5

• When N is less than 10

• When N is greater than or equal to 10

• When N is exactly 9

What is the minimum number of features required for the perceptron to fire?

• 5

• 8

• 10

• 12

What term is used to describe the perceptron's output when it is 1?

• Neuron fires

• Neuron rests

• Neuron sleeps

• Neuron stops
