Robust regression

Thresholding Operator-based Robust RegrEssioN meThod 1. Start with any arbitrary curve and set timer 2. Repeat until convergence i. Create active set using points “close” to ii. Create updated* curve using active set iii. Increment time counter 3. Return final curve Theoretical Guarantees Theorem: TORRENT can resist even an all powerful adversary that corrupts after viewing data and the curve (if < 1/65th fraction of data is corrupted)
