IPA IP 2021 Question 3
A question IPA Japan published in 令和3年度 ITパスポート試験 公開問題 問3, translated into English. ITPEC is based on the same exams.
Same question on ITPEC: Oct 2022 Q91
Which of the following is a term that refers to something that is modeled on the mechanism of a human brain and imitated with a computer program?
Explanation
Neural network — a model of the network of neurons in the human brain, imitated by a computer program.
A neural network connects simple units (artificial neurons) in layers. Each unit multiplies its inputs by weights, adds them up and passes the result on to the next layer. Training adjusts the weights so that the outputs match the training data. Deep learning uses neural networks with many hidden layers, which learn the features of large volumes of data by themselves.
Answer (c)
Why not others:
- •(a) Social network — the relationships among people, or a service (SNS) that connects them online; it models no brain
- •(b) Digital transformation — changing business, products and ways of working with digital technology; a strategy, not a model
- •(d) Brainstorming — a group technique for generating ideas freely without criticism; it uses human brains, it does not imitate one
Key rule: Anything "modeled on the brain" in AI is a neural network; deep learning is a neural network with many layers.
