class pyquickhelper.benchhelper.grid_benchmark.GridBenchMark(name, datasets, clog=None, fLOG=<function noLOG>, path_to_images='.', cache_file=None, repetition=1, progressbar=None, **params)[source]¶

Bases: BenchMark

Compares a couple of machine learning models.

Parameters

name – name of the test
datasets – list of dictionary of dataframes
clog – see CustomLog or string
fLOG – logging function
params – extra parameters
path_to_images – path to images
cache_file – cache file
repetition – repetition of the experiment (to get confidence interval)
progressbar – relies on tqdm, example tnrange

If cache_file is specified, the class will store the results of the method bench. On a second run, the function load the cache and run modified or new run (in param_list).

datasets should be a dictionary with dataframes a values with the following keys:

'X': features
'Y': labels (optional)
