人間の脳神経の仕組みをモデルにして,コンピュータプログラムで模したものを表す用語はどれか。
令和3年度 ITパスポート試験 問3
This question's explanation and your answers so far.
問 3
Incorrectア
A social network refers to a mechanism or service (such as an SNS) that connects the ties between people — friendships and relationships — over the internet. It is not something that simulates the brain's nerve cells, but a network of human relationships, so it is wrong.
Incorrectイ
Digital transformation (DX) refers to an initiative that uses digital technology to transform operations, business models, and an organization's structure and culture. It is a management and transformation concept, not a technology that simulates the brain's nervous system, so it is wrong.
- ウ
正解 The correct answer is ウ (Neural network). The human brain processes information through a large number of nerve cells (neurons) exchanging signals with one another. A neural network is what you get when this mechanism is turned into a mathematical model and simulated inside a computer program, connecting many nodes (artificial neurons) — arranged in an input layer, hidden layers, and an output layer — through connection weights. This exactly matches the question's description of something modeled on the mechanism of the brain's nervous system and simulated by a program, and it is used as a foundational technology for machine learning and deep learning.
Incorrectエ
Brainstorming is a meeting method and ideation technique in which several people freely put forward ideas to broaden their thinking. It is an ideation method carried out by a group of people, not something that simulates the brain's nervous system with a program, so it is wrong.
- Neural network = a mechanism that mathematically models the connection structure of the brain's nerve cells (neurons) and simulates it on a computer using nodes and weights. It is the foundation of machine learning and deep learning.
- Distinguishing confusable katakana terms: grasp the difference from social network (human relationships), digital transformation (DX = business transformation), and brainstorming (an ideation method).
