uwot 0.1.2 (April 6 2019)

Initial CRAN release.

New features

  • New parameter, tmpdir, which allows the user to specify the temporary directory where nearest neighbor indexes will be written during Annoy nearest neighbor search. The default is base::tempdir(). Only used if n_threads > 1 and nn_method = "annoy".

Bug fixes and minor improvements

  • Fixed an issue with lvish where there was an off-by-one error when calculating input probabilities.

  • Added a safe-guard to lvish to prevent the gaussian precision, beta, becoming overly large when the binary search fails during perplexity calibration.

  • The lvish perplexity calibration uses the log-sum-exp trick to avoid numeric underflow if beta becomes large.
