摘要:
在本文中,我们对一种基于目标函数量化的优化技术进行了直观分析。目标函数量化是一种有效的优化方法,它能够减小包含多个鞍点和局部极小值的水平集的测度,并在极限水平集处找到最优点。为了研究基于量化的优化的动力学行为,我们从直观分析出发推导了一个过阻尼 Langevin 动力学模型,以通过迭代量化来最小化水平集。我们认为,基于量化的优化融合了热力学优化和量子力学优化中的量,作为全局优化的核心方法。此外,在所提出的随机微分方程(SDE)基础上,我们利用 Witten-Laplacian 提供了热力学和量子力学分析。在基准函数上的仿真结果比较了非线性优化的性能,证明了基于量化的优化的有效性。
英文摘要:
In this paper, we present an intuitive analysis of the optimization technique based on the quantization of an objective function. Quantization of an objective function is an effective optimization methodology that decreases the measure of a level set containing several saddle points and local minima and finds the optimal point at the limit level set. To investigate the dynamics of quantization-based optimization, we derive an overdamped Langevin dynamics model from an intuitive analysis to minimize the level set by iterative quantization. We claim that quantization-based optimization involves the quantities of thermodynamical and quantum mechanical optimization as the core methodologies of global optimization. Furthermore, on the basis of the proposed SDE, we provide thermodynamic and quantum mechanical analysis with Witten-Laplacian. The simulation results with the benchmark functions, which compare the performance of the nonlinear optimization, demonstrate the validity of the quantization-based optimization.
