Abstract：The research on artificial intelligence is gradually extended to open environment from closed environment. There are various changing factors in open environment leading to evident performance degradation of the traditional models and learning algorithms based on closed set assumption and independently and identically distributed assumption. Therefore, adaptive perception and learning in changing environments is a frontier topic in the field of artificial intelligence. The latest advances are introduced from three aspects. For category changing, research issues of open set recognition and out-of-distribution detection, new categories discovery and class-incremental learning are introduced. For data distribution changing, issues of domain adaptation, domain generalization and test-time adaptation are introduced. For data quality changing, issues of weakly supervised learning and label noise learning are introduced. Finally, future research trends are analyzed and discussed.
