[11:02am] PirosB3: Hi all, question of the day: if I have a array of [x,y,timestamp] vectors, taken every 1-2 seconds, can I calculate it’s path (or the function that passes through every point) ?
[11:02am] PirosB3: I was thinking of something like PCA + some function fitting algorithm
[11:03am] PirosB3: anyone have any suggestions?  thanks
[11:03am] duschendestroyer: when you want a function that passes through every point, that is called interpolation
[11:03am] duschendestroyer: https://docs.scipy.org/doc/scipy-0.14.0/reference/tutorial/interpolate.html
[11:04am] PirosB3: oh great, thanks
[11:04am] PirosB3: if I have some noise in the x,y vectors
[11:04am] PirosB3: do you think PCA is any good to remove it?
[11:04am] duschendestroyer: algorithms in scikit-learn do regression, which does fit a function which has specific characteristics but doesn't necessary pass through every point
[11:05am] PirosB3: duschendestroyer: I don’t want to necessarily use this for prediction
