Safe feature screening rules for the regularized Huber regression

作者:

Highlights:

• Two safe feature screening rules are proposed for the regularized Huber regression.

• These rules can ensure that the dumped features have zero coefficients in solutions.

• The screening rules possess explicit expressions and low computational complexity.

• Experimental results show our rules significantly reduce the computational costs.
