Question

Which of the following activities is performed as part of data pre processing?

Answer 1

Data pre-processing is used for database-driven systems such as CRM- customer relationship management and rule-based systems.

Activities performed as part of data pre-processing are:

Data Cleaning - Data is cleansed through methods like easing the noisy data, filling in missing values, or fixing the discrepancies in the data.

Here noisy data is the one that is the useless data and is not relevant as per the content.

Data Integration - Data with distinctive representations are placed together and frictions within the data are solved.
