1. Any literature stressing the problem of initial sample of active learning?
   • Still have not found any. There are literatures on the imbalance problem, but all the solutions are focusing on how to better sample from the pool when we already have a working classifier.
2. Does imbalanced initial training set actually affects the active learning result?
3. (Comparing to random sampling) Can hierarchical clustering helps to sample more from the minority class to build a more balanced initial training set?
