Picking the best model and corresponding hyperparameters
using cross validation inside a Gridsearch
The grid search provided by GridSearchCV exhaustively generates candidates
from a grid of parameter values specified with the param_grid parameter
Example:
param1 = {}
param1['classifier__n_estimators'] = [10, 50, 100, 250]
param1['classifier__max_depth'] = [5, 10, 20]
param1['classifier__class_weight'] = [None, {0:1,1:5}, {0:1,1:10}, {0:1,1:25}]
param1['classifier'] = [RandomForestClassifier(random_state=42)]
The GridSearchCV instance when “fitting” on a dataset, all the possible
combinations of parameter values are evaluated and the best combination is retained.
cv parameter can be defined for the cross-validation splitting strategy.

Hello Sreeni, thanks for the informative tutorials. 12:00 You have defined 'params' that has hyperparameters for all the models. However, for GridsearchCV the 'pipeline' takes only the 'RandomforestClassifier', aren't you supposed to use the 'param1' that has hyperparameters defined for RandomforestClassifier. Correct me if I am wrong. Thanks!!

i am also thinking so

Amazing video thanks alot, now I can cross validation on models and parameters tuning.😁😁😁

the training of the brat20 dataset in my system is very slow and it showing it exceeds the cpu memory of 10%,can you please give me a solution sir

[@hakankosebas2085]

will be there model tutorial like mask rcnn but faster models and for road segmentation in real time

Great
