Expertise is consensually defined as elite, peak, or exceptionally high levels of performance on a particular task or within a given domain. One who achieves this status is called an expert or some related term, such as virtuoso, master, maven, prodigy, or genius. These terms are me...

ABSTRACT Map-making is an important step for the data analysis of cosmic microwave background (CMB) experiments. It consists converting data, which are typically a long, complex, and noisy collection measurements, into map, image observed sky. We present in this paper new map-making code named picasso (Polarization Intensity CArtographer Scanned Sky Observations), was implemented to construct i...

We describe a new library named picasso, which implements a unified framework of pathwise coordinate optimization for a variety of sparse learning problems (e.g., sparse linear regression, sparse logistic regression, sparse Poisson regression and sparse square root loss linear regression), combined with efficient active set selection strategies. Besides, the library allows users to choose diffe...
