Nice video.
Thank you for the video! Good tutorial!
Obsolete video because: load_boston has been removed from scikit-learn since version 1.2 for ethical reasons.
good stuff to learn
Thanks for the video good sir 🙏
thank youuuuu
Thank you
Great vid : )
useful video
scikit is depricated.
good stuff! very nice place to get started.
When to use OneClassSVM vs IsolationForest for Anomaly detection ?
Hello, first thank u for the video. Ia have a question please, how to tune one class svm and calculate training performance of the model
Here are some common steps you can follow to tune your SVM model. 1. Learn your data, determine the class imbalance and nature of anomalies 2. Apply feature scaling and standardization. 3. Change a kernel (linear, polynomial, RBF, etc) 4. Use cross-validation 5. Do a grid search
more, this is what I'm working on right now
Thanks! simple & straight to the point.
Thanks! simple & straight to the point.
Thanks for posting this video!
thank you
I have the problem with the gaussian mixture models, I don't know how generate outliers uniformly in the p-parallelotope defined by the coordinate-wise maxima and minima of the ‘regular’ observations in R?
how to provide an equation for the regression?
clear tutorial. thanks
Good afternoon, I would like to predict the temperature of a DC motor using this algorithm. Can I use a dataseting that contains (motor current, motor voltage, load) to find such a temperature? Thanks!
Thank you so much sir. very clear very simple. Just the RMSE should be ( mes**(1/2)).
Can anyone please tell me what does the CV MEAN score depicts here?
Hi....how can i get my coefficients ?? Hiw ho find which factor or features are significant ?? Ect
Thanks for the tutorial! But, RMSE is square root of MSE value, right! So RMSE should be, RMSE=MSE**(1/2)
think again
@@mahtabmovahed7336 Sorry, I didn't get you! You mean the formulae shown in the video is correct?
Why didn't you use the fuction: ''' model.coef_ ''' in your linar svm model
it is good, keep going doctor
Thank you very much! This is a very quick start tutorial, I like it. There is no unnecessary information.
Thank you for a quick and simple review and showing how easy you can print out the score for the model!
What is xtrain and ytrain? Can you please explain why xtrain is a 2d array ytrain is a 1d array
Plain and Crystal Clear code application ! Thanks
Glad it helped
Good one.... Thank you
Thanks, your video is very helpful. Can you tell me how to construct a multiclass svm function using this linearSVC ?
Great content, just subbed! You deserve more subs, I think you should use Smzeus”.”com to help grow your channel!
Where is the data? You can't just spit out code and not show us the data you're operating on! That does not contribute to understanding as you're hiding a key piece of information around how this works.
The data is in a 'sklearn.dataset' package, you can load it by using the load_boston() function. And it is clearly mentioned in tutorial
