Request to add linear interpolation imputation method as a new naive model #457
Comments
Hi there 👋, Thank you so much for your attention to PyPOTS! You can follow me on GitHub I have received your message and will respond ASAP. Thank you for your patience! 😃 Best, |
Thanks for proposing this idea, @colesussmeier! We previously used pandas to help generate linear interpolation results, but I think it would be cool to add one implementation into PyPOTS ;-) Could you please make a PR to submit yours? I'll help review your code. |
1. Model description
Linear interpolation (Lerp) imputation method:
I think linear interpolation is a great naive baseline to compare more complicated models to, and would love to see it become part of PyPOTS! I have the code implemented already, so I can make a PR to dev with your consent.
2. Check open-source status
3. Provide useful information for the implementation
Implementation is relatively straight-forward and uses numpy.interp under the hood. I don't have an official paper on it for this use-case but it has been widely used in many domains for many years. Please let me know if you have any questions and if I can submit a PR! Email: colesussmeier@gmail.com :)
