4.3b Can Machines Really Learn?

What is a dataset?

• A collection of numbers
• An organized group of data
• A single piece of information
• A list of rules for machines

What does 'prediction' mean in the context of machine learning?

• A statement about a possible future
• A statement about a certain future
• A command given to a machine
• A guess about the past

What are the three main steps machines use to gain intelligence?

• Creating, evaluating, and applying
• Writing, reading, and speaking
• Datasets, algorithms, and predictions
• Thinking, planning, and acting

How do people often make predictions, as described in the lesson?

• By asking a machine
• By randomly guessing
• By using prior knowledge
• By checking a dictionary

You decide to try a new cake because it looks like one you liked before. What are you using to make this decision?

• A personal dataset
• A machine algorithm
• A random guess
• A future prediction

Why might an AI's predictions be unfair or inaccurate?

• It uses too many algorithms.
• It was trained on limited data.
• It only makes random guesses.
• It was programmed by a machine.

How is an artificially intelligent program different from a non-AI tool like an automatic door?

• Non-AI tools are never programmed.
• Non-AI tools use datasets.
• AI programs make their own decisions.
• AI programs are always controlled by humans.

What makes a computer program or machine artificially intelligent (AI), as opposed to a standard, non-AI program?

• AI programs are always faster than standard programs.
• AI programs require more memory than standard programs.
• Standard programs can learn from data just like AI programs.
• AI programs can learn and adapt, while standard programs follow fixed rules.

What is a neural network?

• A type of machine learning algorithm in AI, inspired by the human brain, that learns by using data to identify patterns and make predictions

• A neural network is a biological system that only exists in animals.
• A neural network is a type of hardware used for data storage.
• A neural network is a social network for connecting people.
