A Stochastic LBFGS Algorithm for Radio Interferometric Calibration
A Stochastic LBFGS Algorithm for Radio Interferometric Calibration
We present a stochastic, limited-memory Broyden Fletcher Goldfarb Shanno (LBFGS) algorithm that is suitable for handling very large amounts of data. A direct application of this algorithm is radio interferometric calibration of raw data at fine time and frequency resolution. Almost all existing radio interferometric calibration algorithms assume that it …
