It is very important for the humans to be always trying to be better and better day after day, in terms of utilization of capabilities, so that we move to our goal step by step, with better and more clear understanding of the situations around us, and hence paving the way for improvement in our approach and logistics, so that we surely achieve what we had set out for; and be less and less affected and influenced by uncertainties in our ways.

In most of the signal processing algorithms, there is a recursion used as follows (for refining the data/information):
present estimate=previous estimate+
gain factor×error.
Here, the gain factor depends on the available current data/information;
and the error is the discrepancy left out from the previous cycle/trial/recursion/iteration.

One can see that the underlying principle in both the processes is the same.
