Autocorr-CLEAN fits clusters of CLEAN components to the residual's autocorrelation function and uses them as adaptive, possibly non-circular basis functions, matching Asp-CLEAN convergence and reaching the noise floor five to ten times faster than classical CLEAN in synthetic tests.

How to make CLEAN variants faster? Using clustered components informed by the autocorrelation function
Autocorr-CLEAN fits clusters of CLEAN components to the residual's autocorrelation function and uses them as adaptive, possibly non-circular basis functions, matching Asp-CLEAN convergence and reaching the noise floor five to ten times faster than classical CLEAN in synthetic tests.
