2.2.0 (Friday 1st May 2020)
......@@ -13,6 +13,12 @@ Changed
* Substantial performance improvements to the :func:`.codeToNumeric` cleaning
function, and to :func:`.removeIfRedundant`, :func:`.binariseCategorical`,
and other processing functions.
* The default implementation of :func:`.removeIfRedundant` now uses matrix
algebra rather thsn pairwise comparisons. This requires more memory, but
is much faster.
* Added [`threadpoolctl`]( as a
dependency, for setting the number of threads to use when parallelising
``numpy`` operations.
......@@ -21,6 +27,8 @@ Fixed
* The :func:`.removeIfRedundant` processing function was not testing columns
with no missing values when a NA correlation threshold was being used.
* :func:`.removeIfRedundant` was also potentially producing inconsistent
results for columns with no present values, or with a constant value.
