"How did you determine the thirty-second lead time?"
"Simulation tests. We ran three thousand sets of simulated data and found that thirty seconds was the optimal balance point. If the lead time is too short, there's not enough time to intervene; if it's too long, the false alarm rate increases. At thirty seconds, the product of sensitivity and specificity is maximal."
"What's the false alarm rate?"
"8.3%, meaning one out of every twelve prediction triggers is a false positive. But the cost of a false positive is very small, just an extra light stimulus without side effects."
Yang Ping nodded, signaling him to continue. Tang Shun truly was a talented multidisciplinary professional; he could write algorithms himself.
