Predictive modeling is a process of developing statistical models and using the models to predict future events and discover relationships among factors based on historical data. Predictive modeling has been widely used in retail and banking in customer loyalty management and credit card fraud detections. In recent years, predictive models have been successfully applied to individual movie selections. Many types of statistical models can be used for predictions. However, commonly used models are regression and logistic regression models. Regression models are used to predict continuous numbers such as individual customer future spending, number of online purchases, and product sales. Logistic regression models are for predicting probabilities of future purchases, coupon redemptions, or credit and loan defaults at individual level. For Artificial Intelligent BI apps, predictive models can be used to do predictions. If you are interested in adding predictive modeling in your business analyses, we are pleased to help.
Machine learning is a process for computer to automatically train models from historical data and use the models to predict future events automatically. As new data is fed, the modeling algorithms automatically train statistical models in order to fit new data. The process keeps going so that the models are updated to produce updated outcomes. There are 3 types of machine learning, such as supervised learning, unsupervised learning, and reinforcement learning. Supervised learning is for solving problems with target values which are the directions of predictions. Regression and classification analyses fall into supervised learning. Unsupervised learning has no targets so computers search for the best fitted groups from input entries. Clustering analysis and Bayesian analysis can be unsupervised learning. Reinforcement learning has no clear targets but has indicators for computers to learn and achieve the best results, such as neural network.
In general, machine learning has six components:
Withe greatly increasing in computer speed and storage and decreasing in computation cost, machine learning processes are becoming popular in commercial use, academics, and many other fields. It is clear that machine learning will continue growing and getting more mature and more uses in next decades.
