In this paper, we first propose a constrained optimization reformulation to the <InlineEquation ID="IEq3"> <EquationSource Format="TEX">$$L_{1/2}$$</EquationSource> <EquationSource Format="MATHML"> <math xmlns:xlink="http://www.w3.org/1999/xlink"> <msub> <mi>L</mi> <mrow> <mn>1</mn> <mo stretchy="false">/</mo> <mn>2</mn> </mrow> </msub> </math> </EquationSource> </InlineEquation> regularization problem. The constrained problem is to minimize a smooth function subject to some quadratic constraints and nonnegative constraints. A good property of the constrained...</equationsource></equationsource></inlineequation>
