What is the main focus of the video by Jabril in CrashCourse AI?

• Teaching John Green-bot to sort mail

• Teaching John Green-bot something

• Teaching John Green-bot to land airplanes

• Teaching John Green-bot to have friendly conversations

Which type of learning involves feedback from an AI's behavior in an environment?

• Supervised Learning

• Unsupervised Learning

• Reinforcement Learning

• Perceptron Learning

What is the process of learning without training labels called?

• Supervised Learning

• Unsupervised Learning

• Reinforcement Learning

• Perceptron Learning

What is the role of a supervisor in supervised learning?

• To provide feedback on AI's behavior

• To point out mistakes during the learning process

• To group data into clusters

• To mimic human neurons

What was the name of the machine created by Frank Rosenblatt?

• Neuron

• Synapse

• Perceptron

• Axon

What is the purpose of the bias in an artificial neuron?

• To increase the strength of signals

• To adjust the eagerness of the neuron to fire

• To decrease the strength of signals

• To mimic human neurons

What kind of function is used in the simplest AI systems to output a 0 or a 1?

• Linear function

• Step function

• Quadratic function

• Exponential function

What does a perceptron do if the sum of inputs is greater than the bias?

• Outputs a 0

• Outputs a 1

• Outputs a random number

• Does nothing

What is the decision boundary in a perceptron program?

• A line that separates different classes on a graph

• A point where the neuron fires

• A threshold for neuron activation

• A random guess by the AI

What is the initial state of John Green-bot's program when sorting bagels and donuts?

• It knows everything about bagels and donuts

• It uses random weights for mass and diameter

• It has pre-trained weights

• It uses a complex neural network
