Data Preprocessing

Feature Engineering Feature Engineering is a systematic process of reducing dimension of data set, creating new features and selecting relevant features for making machine learning model useful. Web Scraping Web Scraping is a method of collecting html data from a website, so that it can be transformed into proper structure for data analysis. Data Exploration and Visualilzation Data Exploration is a method of understanding the structure of given data at high level. It can be done by using statistical or visualization tools.
