Radial Basis Interpolation From Scratch Using Python
This video covers how to implement a one dimensional radial basis function interpolator from scratch using just numpy. A radial basis interpolation is a simple yet power way of approximating nonlinear functions using a small subset of data.

useful, thank you
I'm using pycharm and following along, interpreter didn't give me any issues but I can't see anything, turns out I need to add a plt.show() after plotting, hope this helps anyone else .
Great explanation!

Thank you!
Nice video! Could you please post the code as a link in the description? Much appreciated!
Hi! I like the video, but the sound is to low, is there a way to raise the volume? (my laptop was at 100, I had to connect a radio to be able to listen > . < )

Yes the settings were wrong on my laptop. I recently figured out how to change the mic sensitivity settings so it should work better in future uploads. I don't think I can fix the existing videos, sorry about that.
how did u chose epsilon as 2? how do u choose epsilon

If you have the function you are interpolating, you could take a samples from it at a smaller interval than what you constructed the interpolation with. Then you can build a metric, such as residual squares for multiple epsilon values. Then choose the epsilon that minimizes the error. That's what I would do. I might research the topic more and post a video. Hope this helps
PER ITALIANI: Ho realizzato una playlist sulle reti RBF! :) quì -> kzread.info/dash/bejne/mJd23I9sfsbOc6w.html
Will this code work with multi-dimensional data?

No this is only for one dimensional data. However I do have another video with this same algorithm in multidimensional space
I love that you showed a example of RBF interpolation! Bravo! But you gave me yet another example of why I HATE Python! I could’ve done the same thing in half as many lines with Matlab (Octave if you are poor or cheap), and a human could actually read it and understand what was going on. But nonetheless thanks for the example! Oh, also turn up your volume! I could only barely hear you! That made the video actually a bit painful😢
YOUR VOICE IS TOO LOW.
You can't understand!. I really mean (thankyou).
