SQL and PL/SQL are very powerful languages for machine learning but the visualization capabilities are limited. In this presentation we will see how APEX can be used as a visualization interface for in-database machine learning. We will demonstrate the whole process of predicting beer ratings starting with collecting and analyzing data to implementing the beer rating application made with APEX. And we will visualize the process using APEX. We will be using SQL, PL/SQL, classification, and APEX.
