Backend Changes

Major Changes

• Change behavior of batching to resample only every iteration; not every eval by @MilesCranmer in Change behavior of batching to resample only every iteration; not every eval  astroautomata/SymbolicRegression.jl#421
  • This result in a speed improvement for code with batching=true
  • It should also result in improved search results with batching, because comparison within a single population is more stable during evolution. In other words, there is no lucky batch phenomena.
  • This also refactors the batching interface to be cleaner. There is a SubDataset <: Dataset rather than passing around an array idx explicitly.
  • Note that other than the slight behaviour change, this is otherwise backwards compatible - the old way to write custom loss functions that take idx will still be handled.
