Can result from the bottleneck effect
WebRecently, many semi-supervised object detection (SSOD) methods adoptteacher-student framework and have achieved state-of-the-art results. However,the teacher network is tightly coupled with the student network since theteacher is an exponential moving average (EMA) of the student, which causes aperformance bottleneck. To address the coupling … WebWhich of the following does not result in a decrease of genetic variation? A. natural selection B. genetic drift C. bottleneck effect D. founder effect E. mutation C If the average leg size of a reptile continually got smaller through generations, this would be an example of A. disruptive selection. B. stabilizing selection.
