Abstract: Highlights•We introduce a novel mixed-norm that takes a trade-off between ℓ1-norm and ℓ2,1-norm.•We use ℓ1-norm norm on the loss function to achieve a robust solution.•We derive a simple and provably convergent algorithm based on the alternative directions method of multipliers framework.•Extensive experiments have been done to demonstrate the performance of the proposed method.
