Not all datasets are linearly separable.
A limitation is a derivative of what you mentioned: how to pick a proper kernel to make the data linearly separable? How do we check we have made our data set linearly separable?
Rightly said, Giorgio :)
I vividly remember looking around for the answers myself once I was stuck. There are some great answers here if you wish to read: https://stats.stackexchange.com/questions/131142/how-to-choose-a-kernel-for-kernel-pca.
Thank you, good links
You put in admirable efforts to offer a new angle on data science, each day! Well done
Thanks for appreciating, Giorgio. Really appreciate the kind words :)
