摘要

在全球范围内,软件开发行业最近变得相当复杂。随着所使用的工具和技术不断变化,开发软件的方法也在不断变化。因此,软件工作量评估在此过程中起着至关重要的作用。这就提出了一个挑战,即如何准确地评估软件开发工作量,然后继续执行开发计划。历史显示了各种算法成本估算模型,如Boehm的COCOMO模型、Putnam的SLIM模型、多元回归模型、统计模型和许多非算法软计算模型。尽管有多种技术,但实现更高精度的工作量估计一直是一项挑战。本文关注两种算法回归模型的比较,一种使用多元回归,另一种使用随机森林回归,来预测软件开发工作量的估计。可以观察到,随机森林回归能够成功地对复杂的模型进行建模,通过密切匹配数据集中估计的工作量,提供更好的精度。

Software Development Effort Estimation Using Machine Learning Techniques: Multi-linear Regression versus Random Forest
The software development industry has lately become quite intricate, at a global level. As the tools and technologies used keep changing, so does the approach of developing a software. Thus, software effort estimation plays a critical role in doing so. This arises a challenge of accurately estimating the software development effort, and then proceeding with the plan of development. The history shows various algorithmic cost estimation models like Boehm's COCOMO model, Putnam's SLIM, Multiple Regression, Statistical models, and many non-algorithmic soft computing models]. Despite multiple techniques, achieving a higher accuracy of effort estimation has always been challenging. This paper is concerned with a comparison between two algorithmic regression models, one using Multiple Regression, and another model using Random Forest Regression, to predict the estimation of software development effort. It is observed that Random Forest Regression is successfully able to model the complex, by closely matching the effort estimated in the dataset, providing a better accuracy.
