The proposed paper aims to improve the performance of active learning algorithms by reducing overall error rates and minimizing negative flips. Negative flips occur when correct predictions are forgotten due to increased training sets. The authors observe that reducing one does not necessarily imply a decrease in the other, which is important as current algorithms assume the opposite. They also find that targeted active learning on subsets of the unlabeled pool significantly impacts performance. To address this, they develop ROSE, a plug-in algorithm that utilizes a labeled validation set to restrict acquisition functions to negative flips within the unlabeled pool. The authors demonstrate that integrating a validation set leads to significant improvements in accuracy and negative flip rate reduction.
Low GrooveSquid.com (original content) Low Difficulty Summary
The paper improves active learning algorithms by reducing errors and minimizing “forgetting” correct predictions. It shows that current methods assume the opposite, which is important to know. They also find that focusing on specific parts of the data helps. To help with this, they create a new algorithm called ROSE that uses a small labeled test set to make sure the algorithm only focuses on improving negative flips.
