AI总结:
本文将全维多维缩放应力损失函数与二次外部惩罚项结合,利用惩罚参数递增时的极小化轨迹寻找低维缩放的全局极小值,并通过一二维示例验证。
摘要:
全维(度量、欧几里得、最小二乘)多维缩放应力损失函数与二次外部惩罚函数项相结合。随后,利用惩罚参数递增时的应力极小化轨迹,来寻找低维多维缩放的(试探性)全局极小值。这通过若干一维和二维示例进行了说明。
英文摘要:
The full-dimensional (metric, Euclidean, least squares) multidimensional scaling stress loss function is combined with a quadratic external penalty function term. The trajectory of minimizers of stress for increasing values of the penalty parameter is then used to find (tentative) global minima for low-dimensional multidimensional scaling. This is illustrated with several one-dimensional and two-dimensional examples.
