Forecasting with ARMA models, from a filter point of view

ARMA models are afaik just filters with transfer function $ {MA(z) \over AR(z)} \equiv {FIR(z) \over IIR(z)} $ . However forecasters of stock prices, market trends ... seem to be mainly statisticians, with their own vocabulary and culture. For…

Is there something as self-completing data transfer, like Sudoku?

I would like to know, since I am not that knowledgeable in this subject, if this idea is feasible or widely implemented: If a data package is sent, I know parity-bytes are used to detect errors. Could we not use a similar concept to self-complete…

Is there a repository for source separation test images e.g. the star-galaxy images?

I'm having trouble finding standard images used for testing source-separation algorithms in image processing. For instance, a common example I see is the "star-galaxy" images. Most papers I've seen cite the following paper as their source of the…

Public datasets of signals

Is there a public database where I can find or anyone can provide me real signals. I'm looking specifically for pairs of natural signals (e.g. from Sensor networks) to test some cross-correlation and cross-spectrum methods.

Transient and steady-state analysis for adaptive filter

I have got review for my work saying, that my work (adaptive filter variant) should be analyzed in transient and steady-state before claiming it improves performance. I have done common (in my opinion) analysis: prediction of linear…
