Data Mining Tutorial Current Affairs Apache Data Preprocessing csewustledu

Data Mining is defined as the procedure of extracting information from huge sets of data In other words we can say that data mining is mining knowledge from data The tutorial starts off with a basic overview and the terminologies involved in data mining and then gradually moves on to cover topics Why Is Data Preprocessing Important No quality data no quality mining results garbage in garbage out Quality decisions must be based on quality data eg duplicate or missing data may cause incorrect or even misleading statistics Data preparation cleaning and transformation comprises the majority of the work in a data mining
