to argue that big data analysis could profit from signal amplification.
In astronomy, multiple measures are taken and then combined to amplify a weak signal.
I suspect the signal in astronomy is easier to separate from the noise than in big data.
Perhaps not.
It is certainly an idea that bears watching.
Not to mention documenting amplification your analysis.
Like “boosting” a search term, what is the basis for amplification is a computational artifact?
