After one active learning session, the test results for ‘iter-1’ are as follows:
Active learning to supplement data should increase the accuracy of the dataset, but in my tests, this does not seem to be the case. Could you tell me why the accuracy has decreased after active learning to supplement data. Is there any training experience to share on what strategies can be used to increase the accuracy of the dataset? I hope you can give me some advice. Looking forward to your reply.
