Best teacher with 0 haters.. best channel for ml..ds, dl, ai
bro appko bhi khud se apply karne me dikkat aati he kya me khud se apply nhi kar pa raha hu
Appreciate your effort, I loved way you expand
Best channel for Data science aspirants ❤️❤️ GBU👍👍
Thanks for this, sir! you are great.
Thank You Sir.
thanks for ridge regression, see u all tomorrow.
acha se samjh me aa gya, mai pareshan the ka loss fun +reg. term me min of w kaise nikala jata hai jo ki aaj mujjhe samjh me aa gya
why there is no learning rate hyperparameter in scikit-learn Ridge/lasso/Elasticnet . As it has a hyperparameter called max_iteration that means it uses gradient descent but still there is no learning rate present in hyperparameters . if anyone knows please help me out with it.
Nitish Sir @CampusX @6:42 you multiplied right side by 1/2 but not the left side...I think it may not be mathematically correct...can you or anyone explain the mathematics maybe I am missing something...? also @12.35 2WtXtY ka derivative would be 4 XtY isn't it sir?
yes you are nice observation ....
How can i use regularization with supervised machine learning algorithmic??
Thanks
Thanks Sir
Sir pls explain svm regression
Sir, I am very much happy that we are learning everything regularly. But sir I had a doubt. I have identified some niche topics in ML which are on sklearn API documentation. I don't know if they are important or not. Are we going to cover these:
1. Unsupervised learning
2. Manifold Learning
3. Reinforcement Learning
4. Discriminant Analysis
5. Gaussian Process
6. Multioutput, Multilabel classification
7. Random projection
8. Semi supervised learning
Planning to cover 1,4,6 and 8. Will create separate playlist for 2 and 3
@@campusx-official thanks for your reply.
@@campusx-official Plz also create playlist for GNN, thx.
@@campusx-official 8.34 (Y.T*X*W) but you write as (Y.T*W*X) please ...
Y^tXW hoga
Left side pr 2 balance kr lete sir
sir whats difference btw L=(ypred - y)^2 and L=(y-ypred)^2
in multipe linear regression its 1st one so we got (yT -(XB)T)(y-XB)
but in Ridge Regression its L=(y-ypred)^2 which results (XB-y)T (XB -y)
does it matter or just sign changes
bro it is matrix multiplication, so we can't change order anytime unless we know they commute
L= ( yi - ŷi ) ²
In matrix from
L= ( y - Xw )ᵀ ( y - Xw )
L= ( y - Xw )ᵀ ( y - Xw ) + || w || ²
L= ( y - Xw )ᵀ ( y - Xw) + λ wᵀw
L= ( yᵀ - wᵀ Xᵀ )( y - Xw) + λ wᵀw
L= yᵀ y - wᵀ Xᵀ y - yᵀXw + wᵀXᵀXw + λ wᵀw
As he told wᵀXᵀy and yᵀXw both are same
L= yᵀy - 2(wᵀXᵀy) + wᵀXᵀXw + λ wᵀw
this is same eqn he got
Eg =
(A-B)(C-D) = AC - BC -AD + BD ----- 1
(B-A)(D-C) = BD - AD - BC + AC re-arrange (AC - BC -AD + BD) ---- 2
Both eqn found out to be same
