How can you improve customer segmentation accuracy with data cleaning?
There are a ton of tools and techniques to clean data. Some are statistically rigorous, some are ad-hoc. But, all techniques require you - the data practitioner - to really *understand* the data that you are working with. How it was collected, what it looks like, the shape, the outliers, distributions, scale, time, and context. My number one recommendation for cleaner data: Understand. Your. Data. Then find the right tools to clean it up.

How can you improve customer segmentation accuracy with data cleaning?
In my experience, the quality of a data product is heavily determined by the quality of the input data. Maybe the data is improperly collected, or incomplete, or an outlier. Data is noisy. So, we have no choice but to understand and improve every data set's quality. Data cleaning provides comprehensive, repeatable ways to sanitize input data. In short - data cleaning let's you cut down noise.

Active Files as a Measure of Software Maintainability
International Conference on Software Engineering (ICSE)
In this paper, we explore the set of source files which are changed unusually often. We define these files as active files. Although discovery of active files relies only on version history and defect classification, the simple concept of active files can deliver key insights into software development activities. Active files can help focus code reviews, implement targeted testing, show areas for potential merge conflicts and identify areas that are central for program comprehension.
