Changelog of @hackage/ad 3.2

3.2

  • Renamed Chain to Wengert to reflect its use of Wengert lists for reverse mode.
  • Renamed lift to auto to avoid conflict with the more prevalent transformers library.
  • Fixed a bug in Numeric.AD.Forward.gradWith', which caused it to return the wrong value for the primal.

3.1.4

  • Added a better "convergence" test for findZero
  • Compute tan and tanh derivatives directly.

3.1.3

  • Added conjugateGradientDescent and conjugateGradientAscent to Numeric.AD.Newton.

3.1.2

  • Dependency bump

3.1

  • Added Chain mode, which is Reverse using a linear tape that doesn't need to be sorted.
  • Added a suite of doctests.
  • Bug fix in Forward mode. It was previously yielding incorrect results for anything that used bind or bind' internally.

3.0

  • Moved the contents of Numeric.AD.Mode.Mixed into Numeric.AD
  • Split off Numeric.AD.Variadic for the variadic combinators
  • Removed the UU, FU, UF, and FF type aliases.
  • Stopped exporting the types for Mode and AD from almost every module. Import Numeric.AD.Types if necessary.
  • Renamed Tensors to Jet
  • Dependency bump to be compatible with ghc 7.4.1 and mtl 2.1
  • More aggressive zero tracking.
  • diff (**n) 0 for constant n and diff (0**) both now yield the correct answer for all modes.
