Answer:
Data filtering is the process to filter out unnecessary data.
Explanation:
The process named as data filtering is used for eliminating the rows in order to remove unwanted or unnecessary information. This process is usually done for clarifying the signals of the variables. This removal could possibly reduce the noise. The simplest method of such removal is removing outliers.
Usually, outliers inject noise into the data signal. Removing those outliers will enhance the response of the system. Data mining, machine learning approaches always preprocess the data by removing such unwanted noises.
