This leads us to the following question: given an initial prior probability distribution p S over the secret, how should we select pool designs to test in the lab? Given numbers n & m, test characteristics tpr & tnr as well as prior probabilities of sample infection p i , the best multiset D of m pool designs is the one maximizing some score, like I(S, T (S, D)) or Confidence(S, T (S, D)). 9 Those prior probabilities can then be readily used by our approach to optimize the pool designs, and the ML system can gradually be improved as we gather more test results. ./cache/cord-127025-9ubhd4vf.txt ./txt/cord-127025-9ubhd4vf.txt
