Hi there!

Does AF Analytics support batch calculation? To elaborate my question, we wanted to analyze a whole month of data sets. Initially, I have developed calculations that proactively determines outliers, solves for the linear regression formula and extrapolation before it reaches threshold limits but the person I am working with recommends that if we can do batch calculation instead.

My calculation runs real time. Which means I am able to track outliers as values enters but what if he wanted to gather all data for the whole month and then run the calculation when he has all the data needed?

I have watched PI Batchview and it seemed similar to what he wanted. It's like being able to perform calculation, see it on a trend but the values wont be stored on a tag.

Hi,

There is a difference between AF and the legacy systems such that:

Module Database is now AF

PI Batch Database is now EF

AF and EF are not backward compatible so you can't analyze EF data using PI BatchView. BatchView was useful to overlay batches and define a Golden Batch. Overlaying batches should also now be possible in Coresight 2016.

The realtime algorithm that you developed for outlier detection - if it is using AF Analysis - won't work on historical batch profiles. You would need to develop a separate app for that. Outlier detection in historical batch profiles is also somewhat easier since you can use for example cross validation to determine a threshold.
