How strong are ours hearts? Oracle DV ML helps with the answer.

In this demonstration video, Oracle DV machine learning algorithms are applied on patient health data to predict heart disease likelihood. Multi-classification Machine Learning technique is used in this demonstration. The process shown in the video can be summarized as follows:

1) Get data of patients known to have heart disease. This dataset contains information related to heart disease like Blood Sugar, cholesterol and other medical information about the individual.
2) Create a multi-classification neural net model using that data.
3) Use that model to predict the Heart disease likelihood in other individuals for whom we know their medical history/information.

Example seen in the video can be downloaded from Oracle Analytics Store. Name of the project is Example DV project: Heart Disease Prediction:

More than often most of us (individual users as well as businesses) have access to historical data which contains information on whether a particular event has happened or not; under what conditions has it happened and what are the values of other factors involved in this event. Wouldn't you want to use this historical data to predict whether that event is likely to happen or not? (likely? Less Likely? More Likely? definitely?).

The method of training a model using actual known values of a column, to predict the column value for unknown cases, comes under the domain of Supervised Machine Learning. Oracle Data Visualization comes equipped with inbuilt algorithms to perform such supervised multi-classification and others. Users can choose any one of these algorithms based on the need. Here is a snapshot showing list of inbuilt algorithms in Oracle DV that can perform Multi-classification:
