摘要:

在这篇文章中,我们介绍了监督机器学习工具Feyn。为该工具提供动力的模拟引擎称为QLattice。QLattice是一个受Richard Feynman路径积分公式启发的监督机器学习工具,它探索了许多解决给定问题的潜在模型。它将这些模型公式化为可以解释为数学方程的图形,允许用户完全决定可解释性,复杂性和模型性能之间的权衡。我们简要介绍了QLattice的内部工作原理,并展示了如何将Python包Feyn应用于科学问题。我们展示了它与传统机器学习方法的不同之处,它与它们的共同点,以及它与符号回归的一些共同点。我们描述了这种方法的好处,而不是黑箱模型。为了说明这一点,我们使用一个基本的数据集来完成一个调查工作流程,并展示QLattice如何帮助您推理功能之间的关系并进行数据发现。

英文摘要:

In this article we introduce the supervised machine learning tool called Feyn. The simulation engine that powers this tool is called the QLattice. The QLattice is a supervised machine learning tool inspired by Richard Feynman's path integral formulation, that explores many potential models that solves a given problem. It formulates these models as graphs that can be interpreted as mathematical equations, allowing the user to completely decide on the trade-off between interpretability, complexity and model performance. We touch briefly upon the inner workings of the QLattice, and show how to apply the python package, Feyn, to scientific problems. We show how it differs from traditional machine learning approaches, what it has in common with them, as well as some of its commonalities with symbolic regression. We describe the benefits of this approach as opposed to black box models. To illustrate this, we go through an investigative workflow using a basic data set and show how the QLattice can help you reason about the relationships between your features and do data discovery.
