Re: simple math/statistics problem using map reduce

Hi Mark, It may not be worth it to have a real time estimate of the coefficients A, B if the variance is very small. In other words if your collection of past videos cover most of the different kinds of videos you are likely to encounter then estimates of A, B are likely to be pretty robust and

Thanks. That makes sense. Using map/reduce was as much a curiosity as a practical requirement. Another way to monitor accuracy is to watch my progress indicator and see how close it is to the real time. On Thu, Nov 28, 2013 at 10:50 AM, Nitin Borwankar ni...@borwankar.comwrote: Hi Mark,
