使用所有数据的逆伊辛推断

Inverse Ising inference using all the data

Erik Aurell, Magnus Ekeberg

摘要:

我们表明,一种基于逻辑回归的方法,使用所有的数据,解决了逆伊辛问题远远优于平均场计算只依赖于样本成对关联函数,同时仍然计算上可行的数百个节点。重建的最大改进发生在强相互作用中。使用两个例子,一个稀释的谢林顿-柯克帕特里克模型和一个二维晶格,我们还表明,相互作用的拓扑结构可以恢复从几个样本具有良好的精度和$l_1$正则化的使用是有益的,在这个过程中,推动推理能力进一步进入低温制度。

英文摘要:

We show that a method based on logistic regression, using all the data, solves the inverse Ising problem far better than mean-field calculations relying only on sample pairwise correlation functions, while still computationally feasible for hundreds of nodes. The largest improvement in reconstruction occurs for strong interactions. Using two examples, a diluted Sherrington-Kirkpatrick model and a two-dimensional lattice, we also show that interaction topologies can be recovered from few samples with good accuracy and that the use of $l_1$-regularization is beneficial in this process, pushing inference abilities further into low-temperature regimes.
