新的优化方法 Local LMO 绕过了投影

研究人员引入了 Local LMO,一种用于约束优化问题的新型无投影梯度方法。该方法用当前迭代点周围小球内的局部线性最小化步骤替换了 Frank-Wolfe 的全局线性最小化步骤。Local LMO 在各种情况下提供了与投影梯度下降相当的收敛速度,包括约束集无界的场景,并为光滑强凸函数实现了线性收敛速度。 AI

影响 引入了一种新的优化技术,可以提高具有约束的机器学习模型的训练效率。

    We design Local LMO - a new projection-free gradient-type method for constrained optimization. The key algorithmic idea is to replace the global linear minimization oracle over the constraint set used by Frank-Wolfe (FW) with a local linear minimization oracle over the intersecti…
