Question
Check if the statement is true on balance. How many apply?
Extracting data from an unknown source often requires cleaning
Prior to running an algorithm on a very very large dataset, it would be a good idea to do some EDA.
Nowadays, classification algorithms are often deployed in real time.
Data storage models such as Parquet are designed to present data in a columnar format.
