prcbench 1.1.16

• Cap the numpy thread pool to two threads while the bundled Python module is imported. The pool was sized to the number of cores, which made the CPU time of the import several times its elapsed time

prcbench 1.1.15

• Fix the help page of create_testset, which described the naming convention of benchmark test sets the wrong way round. The prefix 'b' is a balanced set and 'i' an imbalanced one. The 'r' prefix, which uses a random ratio of positives, is now documented too

• Show sklearn in the curve evaluation plot of the readme

• Show recorded running times in the readme, as the mean of each tool on four balanced test sets from 100 to 100,000 data points, instead of timing the tools every time the readme is built. data-raw/run_readme_benchmark.R records them

prcbench 1.1.14

• Add the def7, auc7, and crv7 tool sets that contain all seven tools

• Change the members of the def6, auc6, crv6, def5, auc5, crv5, def4, auc4, and crv4 tool sets. Every predefined set now contains sklearn, and the smaller sets drop PerfMeas, then AUCCalculator, then PRROC

• Return a flat dummy curve from the sklearn tool when reticulate, Python, or numpy is unavailable, in the same way as the AUCCalculator tool does without rJava

• Document that run_benchmark timings of the sklearn tool include the cost of crossing the R/Python boundary and are therefore not comparable with the timings of the tools written in R

prcbench 1.1.13

• Add sklearn as a wrapped tool, calculated by a standalone Python module bundled in inst/python and derived from the scikit-learn source, so scikit-learn itself is not required

• Require reticulate, Python, and numpy to run the sklearn tool, which is requested by name with create_toolset("sklearn") and is not a member of any predefined tool set

prcbench 1.1.12

• Add yardstick as a wrapped tool

• Add the def6, auc6, and crv6 tool sets that include yardstick
