To analyze the data, first of all, we have to preprocess the data to remove the noise and convert it in to an appropriate format so that it can be further analyzed. A collection of data from the real world is mostly full of noise, which makes it difficult to apply any algorithm directly. The raw data collected is plagued by a lot of issues so we need to adopt ways to sanitize the data to make it suitable for use in further studies.
Data preprocessing
Processing raw data
The data collected may also be inconsistent with other records collected over time. The existence of duplicate entries and incomplete records warrant that we treat the data in such a way as to bring out hidden and useful information.
To clean the data, we totally...
