Article evaluation.[edit]
The article I have read is the Data pre-processing Wikipedia article. Here is the link: https://en.wikipedia.org/wiki/Data_pre-processing
It introduces the definition of data pre-processing, the significance of it during the machine learning process, and what components are included in the data pre-processing, meaning that everything in the article is related to the article topic and nothing distracted me. No information in the article is out of date, the methods of data preprocessing the article introduced are still being widely used. And in my point of view, there is nothing missing. However, I think there is one point to be improved. That is the article should introduce the methods of data preprocessing and procedures while preprocessing data, letting the beginners have a deep understanding.
In addition, all claims of the article are neutral, they are neither overrepresented nor underrepresented. And all links for the citations work. I have checked the sources and they all support the claims that the representation and quality of data are first and foremost before running an analysis, and data preprocessing is the most important phase of a machine learning project.
