GridSearchCV vs RandomizedSeachCV|Difference between Grid GridSearchCV and RandomizedSeachCV
#GridSearchCVvsRandomizedSeachCV #UnfoldDataScience
Hello,
My name is Aman and I am a data scientist.
About this video,
In this video , I talk about the major difference between RandomizedSeachCV and GridSearchCV. I explain what are the techniques of cross validation in GridSearchCV and RandomizedSeachCV . I also discuss when to use RandomizedSeachCV and GridSearchCV . Below questions are answered in this video:
1. What is GridSearchCV
2. What is RandomizedSeachCV
3. GridSearchCV vs RandomizedSeachCV
4. Difference between Grid GridSearchCV and RandomizedSeachCV
5. When to use Grid GridSearchCV and RandomizedSeachCV
6. Concept of cross-validation
About Unfold Data science: This channel is to help people understand basics of data science through simple examples in easy way. Anybody without having prior knowledge of computer programming or statistics or machine learning and artificial intelligence can get an understanding of data science at high level through this channel. The videos uploaded will not be very technical in nature and hence it can be easily grasped by viewers from different background as well.

Very clearly explained.. Thanks for making this look so simple.. I have a query here.. As you mentioned when we have a large dataset we shouldnot go for GridSearchCV. So in this scenario can we run the GridSearchCV on some random samples of the large dataset and pass on those set of parameters to RandomSearchCV

Hi Abhishek, can do that however it might not be true parameters for larger data.

@haribattula5187 2 жыл бұрын

Thanks mate for the valuable information!! I love the way you pointing about no of iterations directly proportional to no of parameters we pass and CV number.. Let us consider one scenario that I already know 5, 100 are best hyper parameters that we can get for the given data, but when I perform RandomizedSearchCV then it gives 3, 100 as best hyper parameters among them, it just skipped trying 5,100 since it is selecting randomly.. is there any implementation in sklearn RandomizedSearchCV api that won't ignore best possible hyperparameters, if not then is it good to perform gridseachcv over randomcv although it is computationally slow or is there any other way to go for...?
