[Retracted] Review on the Application of Metalearning in Artificial Intelligence

Table 3

Challenges and countermeasures of metalearning.

	Technical aspects	Application aspects
Specific problem	Costly; Poor learning ability for complex tasks; Single learning method of metaknowledge	Difficulty in obtaining data; Inconsistent task distribution
Response plan	Improving model training performance; Studying the continuity of action execution; Metaknowledge combination learning	Building a training task database; Learning from the experience of other algorithms [67–69]
