Hi Guys, im trying to generate a subset of data from a time series electronic health record using the idea of sliding windows.
I have implemented this in sql but its taking 13 hours to process which is not ideal, i know python can do this much faster unfortunately i'm not very proficient in python and wondered if anyone has this code readily available. The variable or parameter are Window size, Gap size Step size and prediction window size.
Or if you can point me in the right direction as to a tutorial online or anything of the sort.
Much appreciated
A queue data structure is good for implementing gliding windows. It resembles a list where a new items are inserted at one end and deleted at the other end. Most programming frameworks come along with a ready-made queue class.
Queues are usually implemented that an enqueue / dequeue operation have an O(1) complexity. The contents are not 'shifted' entirely when an element is added or deleted.
Regards,
Joachim
