Predictive Analytics vs Data Mining – Which One Is More Useful

Difference Between Predictive Analytics and Data Mining

Predictive analytics is the process of refining that data resource, using business knowledge to extract hidden value from those newly discovered patterns. Data mining is the discovery of hidden patterns of data through machine learning — and sophisticated algorithms are the mining tools.

Data mining + Domain knowledge => predictive analytics => Business Value

Key Differences Between Predictive Analytics vs Data Mining

Below is the difference between Predictive Analytics and Data Mining

●Process – Process of Data Mining can be summarised into six phases-

a.Business/Research Understanding Phase – Clearly enunciate the project objectives and requirements in terms of the business or research unit as a whole
b.Data Understanding Phase – collect and use exploratory data analysis to familiarize yourself with the data, and discover initial insights.
c.Data Preparation Phase – Clean and apply a transformation to raw data so that it is ready for the modeling tools
d.Modeling Phase – Select and apply appropriate modeling techniques and calibrate model settings to optimize results.
e.Evaluation Phase – Models must be evaluated for quality and effectiveness before we deploy.Also, determine whether the model, in fact, achieves the objectives set for it in phase 1.
f.Deployment Phase – Make use of models in production.might be a simple deployment like generate a report or a complex one like Implement a parallel data mining process in another department.

High-level steps of Predictive Analytics process area

a.Define Business Goal – What business goal to be achieved and how data fits.For example, business goal is more effective offers to new customers and data needed is segmentation of customers with specific attributes.
b.Collect Additional Data – Additional data needed might be user profile data from online system or data from third-party tools to better understand data.This helps to find a reason behind the pattern.Sometimes Marketing surveys are conducted to collect data
c.Draft Predictive Model – Model created with newly collected data and business knowledge.A model can be a simple business rule like “There is a greater chance to get convert the users from age a to b from India if we give offer like this” or a complex mathematical model.

●Business Value – Data Ming itself adding values to business like

a.Deeply understand customer segments across different dimensions
b.Get performance pattern specific to KPIs (Eg. Is subscription increasing with active users count?)
c.Identify Fraudulent activity attempts and prevent it.
d.System performance patterns (Eg -Page loading time across different devices – any pattern?)

Predictive analytics empowers organization by providing three advantages:

a.Vision – Helps to see what is invisible to others.Predictive analytics can go through a lot of past customer data, associate it with other pieces of data, and assemble all the pieces in the right order.
b.Decision – A well made predictive analytics model provides analytical results free of emotion and bias.It provides consistent and unbiased insights to support decisions.
c.Precision – Helps to use automated tools to do the reporting job for you — saving time and resources, reducing human error, and improving precision.

●Performance measure – Performance of Data Mining process measured on how well the model finding patterns in data.Most of the time it will be a regression, classification or clustering model and there is a well-defined performance measure for all these.
Performance of predictive analytics is measured on business impact.For example – How well the targeted ad campaign worked compared to a general campaign?. No matter how well data mining finding patterns, to work predictive models well, business insight is a must.

●Future – Data Mining field is evolving very fast.Trying to find patterns in data with lesser data points with a minimum number of features with help of more sophisticated models like Deep Neural Networks. Lot of pioneers in this field like Google also trying to make the process simple and accessible to everyone.One example is Cloud AutoML from Google.
Predictive analytics expanding to a wide variety of new areas like Employee Retention prediction, Crime Prediction (aka predictive policing) etc.At same time organizations trying to predict more accurately by collecting maximum information of users like where are they going, what type of videos watching etc.

 Conclusion -Predictive Analytics vs Data Mining

As Rick Whiting said in InformationWeek What’s next is what’s next.Predictive analytics is where business intelligence is going.Data Mining helps organizations in any way and one of the most important in that is created a good foundation for Predictive Analytics
