Machine Learning Toric Duality in Brane Tilings

  • 用全连接神经网络识别共形费米子理论的对偶类
  • 在$Y^{6,0}$模型上预测规范线性σ模型多重度,平均误差仅0.021
  • 验证模型鲁棒性,揭示学习机制与理论空间扰动的关系

我们将多种机器学习方法应用于4d $/mathcal{N}=1$ 超对称量子场论中的塞伯格对偶研究,这些理论来自探测双有理卡拉比-丘3流形的D3膜世界体积。这类理论可用称为晶格镶嵌或二分图模型的环面平铺优雅描述。复杂的红外对偶网络将这些理论空间划分为普适类,其预测与分类天然适合机器学习分析。本文开展初步探索:首先,在$\mathbb{Z}_m \times \mathbb{Z}_n$取模的锥面构造上训练全连接神经网络,识别塞伯格对偶类,达到$R^2=0.988$;接着评估方法对理论空间扰动的鲁棒性,并据此讨论神经网络的学习本质;最后采用更复杂的残差架构,对$Y^{6,0}$理论的双有理相空间进行分类,并预测其塔式图中规范线性σ模型的多重度。尽管任务复杂,结果仍极为精确:在固定凯斯特莱因矩阵代表元的前提下,回归器的平均绝对误差为0.021。我们还讨论了放松该假设对性能的影响。

原文摘要 · Abstract (English)

We apply a variety of machine learning methods to the study of Seiberg duality within 4d $\mathcal{N}=1$ quantum field theories arising on the worldvolumes of D3-branes probing toric Calabi-Yau 3-folds. Such theories admit an elegant description in terms of bipartite tessellations of the torus known as brane tilings or dimer models. An intricate network of infrared dualities interconnects the space of such theories and partitions it into universality classes, the prediction and classification of which is a problem that naturally lends itself to a machine learning investigation. In this paper, we address a preliminary set of such enquiries. We begin by training a fully connected neural network to identify classes of Seiberg dual theories realised on $\mathbb{Z}_m\times\mathbb{Z}_n$ orbifolds of the conifold and achieve $R^2=0.988$. Then, we evaluate various notions of robustness of our methods against perturbations of the space of theories under investigation, and discuss these results in terms of the nature of the neural network's learning. Finally, we employ a more sophisticated residual architecture to classify the toric phase space of the $Y^{6,0}$ theories, and to predict the individual gauged linear $σ$-model multiplicities in toric diagrams thereof. In spite of the non-trivial nature of this task, we achieve remarkably accurate results; namely, upon fixing a choice of Kasteleyn matrix representative, the regressor achieves a mean absolute error of $0.021$. We also discuss how the performance is affected by relaxing these assumptions.
