Or simply a delta off the last delta (or mean of last n deltas, I guess), so you can do the compression in a stream.

- jhgb 5y agoThat might also be equivalent to one of the ARMA models, although I'd have to do the math to prove that (and to derive which one corresponds to what you're describing). Edit: It seems that if you detrend the data, the "delta off the last delta", if I understand it correctly, is an MA(1) model. I think. Maybe. My math is wobbly.
- wallacoloo 5y agoIf I understand you & GP, these are both just particular instantiations of Linear Predictive Coding [1]. For both of these approaches, you’d probably get similar or better results just throwing your data into an off-the-shelf LPC, and with less effort.
