Ising反问题的小相关展开

Small-correlation expansions for the inverse Ising problem

Vitor Sessak, Rémi Monasson

摘要:

我们提出了一个系统的小相关扩展来解决逆伊辛问题:找到一组耦合和对应于一组给定的相关性和磁化的字段。耦合计算到第三阶的通用磁化的相关性,并在零磁化的情况下的第七阶;此外,我们展示了如何总结一些有用的类图准确。由此产生的扩展优于现有的算法上的谢灵顿-柯克帕特里克自旋玻璃模型。

英文摘要:

We present a systematic small-correlation expansion to solve the inverse Ising problem: find a set of couplings and fields corresponding to a given set of correlations and magnetizations. Couplings are calculated up to the third order in the correlations for generic magnetizations, and to the seventh order in the case of zero magnetizations; in addition we show how to sum some useful classes of diagrams exactly. The resulting expansion outperforms existing algorithms on the Sherrington-Kirkpatrick spin-glass model.
