Luca Trevisan showed how many constructions of pseudorandom generators can in fact be thought of as extractor constructions:
Is there a meaningful converse? I.e., can "natural" constructions of extractors be thought of as pseudorandom generators (PRG) constructions?
Extractor constructions seem to correspond to distributions over PRGs (such that any distinguisher won't succeed in distinguishing for almost all of them). Are there known applications for this?
