Changes in version 0.3.1 (2026-04-29)                  

Bug fixes

  - Fix KLIEP() so that compute_density_ratio() evaluates density ratios
    for the input data passed to the function, rather than reusing the
    training data (#13).

                 Changes in version 0.2.1 (2019-06-30)                  

New feature

  - Implement RuLSIF [Yamada et al. 2011] to estimate relative density
    ratio.

                 Changes in version 0.1.1 (2019-05-08)                  

Bug fix

  - Modify Euclidean distance to square Euclidean distance in the
    function that computes Gaussian kernel (#6, @ya103). It affects all
    algorithms in the packages.
