Weak Supervision for RFI Mitigation in 21-cm Cosmology

Seminar
Room 112 (Watanabe Hall)
Journal Club

Speakers: Dr Shawn Dubey Detecting the redshifted 21-cm signal from the early universe requires separating an extremely faint cosmological signal from bright foreground emission and terrestrial radio-frequency interference (RFI), but flagging RFI is a big challenge. I will describe our use of weak supervision, a method that combines multiple imperfect flaggers to construct training labels ... Read more
