解説
問 74
Incorrectア
The statement that it is “an environment in which various information devices such as PCs, mobile phones, and information appliances exist everywhere in society, allowing connection to a network anytime and anywhere” describes ubiquitous computing (a ubiquitous network society) and has nothing to do with a neural network.
Incorrectイ
The statement that it is “a network for academic research purposes that connects universities and research institutions, operated by the National Institute of Informatics (NII)” describes the academic information network SINET, which is a different thing from a model that imitates the nervous system.
Incorrectウ
The statement that it is “a system in which local governments nationwide network information such as name, date of birth, gender, and address so that it can be retrieved from a local government other than the place of residence” describes the Basic Resident Register Network (Juki-net) and is not a neural network.
- エ
正解 A neural network is a mathematical model that imitates, on a computer, the human brain's nerve cells (neurons) and the way they connect, and it is used as the foundational technology of deep learning. Nodes in the input layer, hidden layer, and output layer are connected with weights, and by adjusting the weights through learning, it performs tasks such as pattern recognition. Therefore, choice “エ”, which describes it as “a model that uses a computer to imitate the mechanism of the brain's nervous system, used in deep learning and similar fields,” is the most appropriate.
ここがポイント
- A neural network is a mathematical model that imitates the way the brain's nerve cells (neurons) connect, and it is the core technology of deep learning.
- The confusing choices (ubiquitous computing, SINET, Juki-net) are different concepts with similar names or purposes; the key point is not to mistake which object the definition refers to.
