WebThere are many norms that lead to sparsity (e.g., as you mentioned, any Lp norm with p <= 1). In general, any norm with a sharp corner at zero induces sparsity. So, going back to the original question - the L1 norm induces sparsity by having a discontinuous gradient at zero (and any other penalty with this property will do so too). $\endgroup$ WebApr 8, 2024 · 最简单的决策树实例项目:心脏病分析和预测.
