解説
問 10
Incorrectア
“Echo chamber” refers to the phenomenon where repeatedly being exposed only to opinions similar to one's own, such as on social media, amplifies and reinforces particular opinions or beliefs. It is a term about the information environment and human cognition, unrelated to generative AI producing incorrect output, so it is wrong.
Incorrectイ
“Singularity (technological singularity)” refers to a hypothetical turning point at which AI surpasses human intelligence and technological progress accelerates beyond prediction. It is a concept about predicting the future, not a term describing AI producing factually incorrect output, so it is wrong.
Incorrectウ
“Deepfake” refers to the technology that uses AI (deep learning) to synthesize or alter a person's face or voice so closely to the real thing that it creates fake images, videos, or audio. It is deliberately fabricated content, a different concept from hallucination, in which a generative AI unintentionally produces misinformation, so it is wrong.
- エ
正解 Choice “エ”, Hallucination, is correct. Hallucination (hallucination) refers to the phenomenon in which a generative AI (such as a large language model) produces content that looks plausible and reads naturally, yet is factually wrong or does not actually exist. Because the AI generates plausible-sounding text by following the statistical patterns in its training data, it may confidently return incorrect answers even without any supporting facts. This exactly matches the question's description of output that appears plausible but is not factually correct, so “エ” is the most appropriate.
ここがポイント
- Hallucination is the phenomenon where a generative AI, following the statistical patterns in its training data, produces content that appears plausible but is not factually correct; it is a typical caution when using generative AI (outputs need fact-checking).
- Distinguish the easily confused AI-related terms: hallucination (erroneous automatic generation), deepfake (intentional fake synthesis), singularity (technological singularity), and echo chamber (amplification of opinions); grasp each correctly.
