Future Directions
	n Discovering Hidden Variables n Can we use Active Learning to guide us? n Coping with Missing or Unlabeled Data n Use unlabeled pool to improve SVM performance n Allow incorporation of partial experimental results n Different action costs n Performing some experiments more costly than others n Extra cost to observe some domain variables n E.g., should we perform NMR scan on this patient or not? n Scaling up to even larger domains n Images databases with millions of images
