How clustering work in data cleaning?
Our intuition that underpins cleaning by clustering is that, dividing keys into different clusters resolves the scalability issues for data observation and cleaning, and keys in the same cluster with duplicates and errors can easily be found. Our algorithm can also be applied to other biomedical data types.

What does it mean to clean a dataset?
Also known as data cleansing, it entails identifying incorrect, irrelevant, incomplete, and the “dirty” parts of a dataset and then replacing or cleaning the dirty parts of the data. Although sometimes thought of as boring, data cleansing is very valuable in improving the efficiency of the result of data analysis.

Which is the first step in data cleaning?
Since one of the main goals of data cleansing is to make sure that the dataset is free of unwanted observations, this is classified as the first step to data cleaning. Unwanted observations in a dataset are of 2 types, namely; the duplicates and irrelevances.
Why is data cleansing important in data analysis?
Although sometimes thought of as boring, data cleansing is very valuable in improving the efficiency of the result of data analysis. It generally helps to improve data quality, and the process can be automated or done manually. The process of data cleansing may involve the removal of typographical errors, data validation, and data enhancement.
