If you are working on big data constantly, then you must've come across the term predictive analytics models and algorithms. Data science, predictive analytics, and prescriptive analytics are some of the major terms used in big data analytics. They define the use of mathematical technique to enhance business concepts. In a nutshell, predictive analytics models and algorithms solve many business problems including churn reduction, dynamic pricing, equipment utilization, fraud detection, health decision, inventory management, offer optimization, risk management, and predictive maintenance.
Predictive analytics models and algorithms help businesses anticipate future outcomes using data modelling and big data. The disruptive method is seen as an accurate detector of companies' future. With the help of predictive analytics models, businesses can make plans and strategies and execute them at the right time. In technical terms, predictive analytics modelling is a statistical technique using machine learning and data mining methods to forecast the future of business with the help of historical data. The predictive analytics models and algorithms, are designed to assess historical data, discover patterns, observe trends, and use that information to draw up predictions about future outcomes. Predictive analytics modelling can be used for everything starting from small tasks like customers' choice to big tasks like anticipating TV ratings. But predictive analytics modelling is not a one-time work. It needs constant feeding of data and the improvements need to be tracked now and then. When new data comes in, it could possibly indicate behavioural changes of customers, which could reflect the outcomes. The biggest advantage of predictive analytics models is that it acts instantly and delivers answers in real-time, making it easy for financial and retail organizations to calculate the outcomes. In this article, we take you through the types of predictive analytics models and algorithms and explain how they are developed.
Classification models play the basic role of sorting data and putting it in different slots. It is very vital for predictive analytics models and algorithm as the whole prediction process begins from there. Classification models put data in categories based on what is abstracted from historical data. Generally, this method of predictive analytics modelling is good at answering 'yes' or 'no' questions based on broad analysis. The classification model can answer basic questions like 'Will this customer shop here again?' 'Will this application pass the loan test?' and 'Is it a fraudulent transaction?' Besides, when new big data comes in, the classification models redefine themselves to house them and provide revised answers.
The forecast model is very important in predictive analytics modelling, as it handles metric value prediction by estimating the values of new data based on learnings from historical data. It is very vital because of its acceptance of both historical and current data. Forecast models generate numerical values when there is none to be found and enhance business outcomes. It can multi-task and also leverage answers for diverse industries without discrimination. For example, sales departments use a forecast model to predict the number of purchase customers will make and on the other hand, it can anticipate the number of products a manufacturing unit can produce per day.
When it comes to analyzing data, there is always some trouble with big data that doesn't fit in the parameters. Outliner models are used to counter those challenges. It analyzes abnormal or outlying data points and delivers accurate answers. Generally, the outliner model is used to predict abnormal activities and transactions. For example, an online seller can predict transaction abnormalities by using the outliner model. He/she can check if the customer did a transaction out of normal methods.
The clustering model in predictive analytics modelling is used to target customers based on their preference. In a nutshell, it is mostly used for marketing campaigns to attract new buyers and influence old buyers to try out new products. Cluster models sort data into separate, nested smart groups based on similar attributes. Later, the company uses it to sort and promote relative products to the customers who are most likely to buy them. Besides, the cluster model method is seen as a time-effective way of using big data as it sorts and delivers the answers quickly. They segregate customers into smaller groups based on their preferences and devise promotion methods specifically for each group.
While all the above-mentioned types focus on historical data and its outcomes, the time series model encounters the challenge of customer preference over a period of time. Consumers have the evolving mindset when it comes to their choice of purchase. Only the time series model gets to address those concerns in predictive analytics modelling. The time series model focuses on data where time is the input parameter and works on different data points to develop a numerical metric to predict trends.
