Data Science- Visualizing Data and Exploring Models

This course begins by discussing the importance of data exploration. It will teach you what to use for data visualizations in R and in Python. You will study different plots for different views such as scatter and line plots, bar plots, histograms, box plots, violin plots, Q-Q plots. You will also learn that scatter plot of individual columns can be useful for detailed exploration of the features in your dataset.

You will then study feature engineering which is the process of using domain knowledge of the data to create features that make machine learning algorithms work. You will look into models which are evaluated based on statistics about the errors, or residuals, in the predicted values. You will study the features and methods available in R and Python for creating Machine learning models including the process and options for evaluation.
