Discussion of Function Specification for Dataset Types
======================================================

Some talking points from the September 2 meeting:

 * Datasets as views/tasks (Pascal Vincent's idea): our dataset specification
 needs to be flexible enough to accommodate different (sub)tasks and views of
 the same underlying data.
 * Datasets as probability distributions from which one can sample.
 * Our specification should allow transparent handling of infinite datasets (or
 simply datasets which cannot fit in memory)
 * GPU/buffering issues.
