解説
問 21
Incorrectア
A mechanism that integrates information and business flows across customer-related departments such as sales, marketing, and after-sales service describes CRM (Customer Relationship Management) and has nothing to do with deep learning.
Incorrectイ
A form of education, learning, and training carried out using digital devices and communication networks describes e-learning, a term that refers to a “form” of learning. The “learning” in deep learning means data learning performed by a computer, which is a different concept.
Incorrectウ
A mechanism that shares the knowledge and know-how held by each individual in an organization across the whole organization and uses it effectively describes knowledge management, which targets the sharing of knowledge held by people and is different from deep learning.
- エ
正解 Deep learning is a technology that feeds large amounts of data into a model built by stacking many layers of a “neural network” that mimics the neural circuits (neurons) of the human brain, so that the computer itself automatically extracts and learns the important “features” from the data. Choice エ, “a technology in which a computer itself extracts and learns the features of data by analyzing large amounts of data using a model that mimics the neural circuits of the human brain,” describes exactly this mechanism, so it is the correct answer. In conventional machine learning, humans had to design the features, but in deep learning the machine performs even the feature extraction, and that is the key point.
ここがポイント
- Deep learning = a technology that uses a multi-layer neural network mimicking the neural circuits of the brain, in which the computer itself extracts and learns features from large amounts of data.
- Distinguishing it from confusable terms: ア = CRM (Customer Relationship Management), イ = e-learning, ウ = knowledge management. All contain words such as “learning” or “information,” but their targets and purposes differ.
