摘要

根据破产法第13章解除破产是出了名的困难。过去的实证研究得出结论,只有三分之一的第13章债务人根据其计划完成其义务并获得第13章的解除。许多案件最终被驳回,或根据第七章被转为案件。联邦司法中心最近提供的新数据显示,近年来,只有约39%的第13章申请人成功获得第13章的释放。这些都是很低的数字。在这个项目中,我研究了美国联邦司法中心在2017年提供的一个公共案件级数据库,该数据库基于美国法院行政办公室收集的信息。该项目检查了这些数据的范围和质量,以及将其用于高级统计分析和机器学习模型应用所需的步骤。这个项目超越了这样的描述性统计。它使用机器学习算法——所谓的人工智能——描述了一个模型,该模型可以使用来自联邦司法中心综合数据库的数据,仅根据初始请愿书和时间表摘要中提供的信息,预测债务人是否会获得第13章的解除。该模型能够以70%的总体准确率预测病例结果,并且对于大约25%的病例可以以超过90%的准确率预测结果。当案例预测与实际案例结果交叉引用时,该模型可以为特定案例分配高度准确的成功概率。该模型使用随机森林决策树算法来实现其结果,尽管使用神经网络也获得了几乎相似的结果。该模型、相关脚本、相关文件和使用说明可通过Github /warrenagin/Ch13Learner在线获得。

Using Machine Learning to Predict Success or Failure in Chapter 13 Bankruptcy Cases
Obtaining a chapter 13 bankruptcy discharge is notoriously difficult. Past empirical studies conclude that only one-third of chapter 13 debtors complete their obligations under their plans and obtain a chapter 13 discharge. Many cases end up dismissed, or converted to a case under chapter 7. New data recently made available by the Federal Judicial Center, shows that in recent years only about 39% of chapter 13 filers successfully obtain their chapter 13 discharges. These are low numbers. In this project I examined a public case level database made available in 2017 by the US Federal Judicial Center, based on information collected by the Administrative Office of the United States Courts. The project examines the extent and quality of this data, and the steps needed to use it for advanced statistical analysis and application of machine learning models. This project goes beyond such descriptive statistics. Using machine learning algorithms – so-called artificial intelligence – it describes a model that can predict, using data from the Federal Judicial Center's Integrated Database, whether a debtor will obtain a chapter 13 discharge based only on information provided in the initial petition and summary of schedules. The model is able to predict case results with 70% accuracy overall – and for about 25% of cases can predict results with more than 90% accuracy. When case predictions are cross-referenced against actual case results, the model can assign to specific cases a highly accurate probability of success. The model uses a random forest decision tree algorithm to achieve its results, although nearly similar results were also obtained using a neural network. The model, relevant scripts, and related files and instructions for use are available online through Github at /warrenagin/Ch13Learner.
