Predictive Analytics is the sub-branch of Advanced Analytics, the key area of Data Science that uses Statistical concepts to output an event's maximum likelihood. Mathematics and Statistics are the building blocks of Predictive Analytics. It looks into the historical data and finds the trends & patterns from it by using the statistics and build the strategy to apply on new data to compute and predict the best possible outcomes.
It is based not only on statistical terms but also on data mining that provides Knowledge Discovery and Data-Driven features related to the prediction. You may also learn more about Cognitive Analytics in this insight.
Predictive Analytics help you determine what will happen—how well a product will sell, who is likely to buy it, which marketing to use for the greatest impact. Source - The Future Of Data Analytics
What are the types of Predictive Analytics?
Based on the computation strategy, Predictive Analytics broadly classified into below given two classes -
This approach of modeling uses the Equation-Based models that describe the whole phenomenon under consideration. Example: Time-Series Regression and Linear Regression.
This modeling relies on the models that are not easy to explain in the form of the equation and often requires the simulation of the built functions for making the prediction called 'Black-Box Prediction Modelling' because the model structure does not provide the insights into factors that can map models Inputs to outputs. Example: Neural Networks.
Are you confused with Predictive and Prescriptive Analytics?
Prescriptive Analytics is the next step to Predictive analytics. Prescriptive analytics is the branch of Data Analytics that uses Predictive Modelling to suggest the actions to be taken for getting the optimal outcome. It relies on Optimization and Rule-based Techniques for Decision-Making. E.g., Forecasting the load on the energy grid over the next 24 hours is predictive analytics, while how to operate the power-plant based on the forecast of energy load is Prescriptive Analytics.
How Predictive Analytics works?
It incorporates and performs the Knowledge Data Discovery steps and forecasts the maximum likelihood outcome as the prediction. It combines Data mining, Machine Learning to result in qualitative and quantitative predictions for the future. Each one of these is as important as others for estimating the outcome.
These are four necessary steps to be taken for reaching Prediction -
Access and Explore Data- The necessary and relevant data acquisition is made from various data sources like sensors, databases, data lakes, etc.
Pre-processing and Aggregating Data- Here, the data results in the removal of messy data and transformed into the required format, along with the selected features extracted.
Predictive Models Development- Statistical and Computational approaches are used to create the models and their experiments to optimize parameters used while training and monitoring the performance.
Integration with Real-Time Systems- Now, the integration of Predictive and Prescriptive analytics comes into the picture to generalize the Intelligent system that functionally works on the Predictive Building and behaves in the way as prescriptive implements.
Predictive analytics combines various data analysis techniques; likewise, data mining, machine learning, and many more. Listed below are the methods involved in analytics:
A decision tree is an analytics technique based on Machine Learning, uses algorithms from data mining to predict the possible risks and rewards of pursuing several different actions. It is a visual chart that resembles an upside-down tree, which illustrates a decision's potential outcome. It can solve all types of classification problems and answer the tricky questions when deployed for analytics.
Text Analytics comes into use when an organization willing to predict a numerical value. It is based on Statistical, Machine Learning, and linguistics techniques. It helps to predict the topics of a document, and also it examines words used in the given form.
Biological data analytics techniques inspire neural Network analytics—Machine Learning-based predictive analytics techniques, which intake past and current data to estimate future values. Neural Network Algorithm enables them to counter complex correlations buried in data to detect the human brain's detection mechanisms.
What are the benefits of Enabling Predictive Analytics?
Predictive Analytics emerges the Insights from the data. It uses them to identify risks and patterns that help in making decisions in most areas like Business, Finance, Public Safety, Healthcare, and many others. Most of the Machine Learning and Artificial Intelligence applications are using Predictive Analytics as the core tool.
