Predictive analytics is the use of data, statistical algorithms and machine learning techniques to predict future outcomes. Organizations use it to determine trends, risks and opportunities. This editorial explains predictive analytics in simple terms, along with real-world examples, tools and techniques.

What is Predictive Analytics?

Predictive analytics utilizes a variety of techniques including predictive modeling, data mining, machine learning, statistics, and artificial intelligence to analyze current and historical data to make predictions about unknown future events. The core premise lies in identifying patterns in data to determine the likelihood of future outcomes based on the insights derived from these patterns.

Predictive analytics is all about forecasting what will happen in the future. Several industry verticals use predictive analytics including banking, insurance, retail, healthcare, pharmaceuticals, telecom, and government agencies. It enables more informed and proactive business decisions through predictive intelligence.

In simple words, predictive analytics is about making predictions using data. Companies use past and current data to guess what might happen in the future. For example, an online shopping company can analyze past purchases to predict what items a customer might buy next.

A bank can analyze past transactions to detect fraud. Doctors use patient information to predict the risk of developing a disease. So predictive analytics helps make educated guesses about unknown future events.

The most commonly used predictive analytics models include:

Regression Analysis: Used to predict a numerical value, like product demand, based on correlating factors.
Decision Trees: Tree-like models depicting outcomes from a series of decisions. Helps evaluate effects of multiple variables.
Time Series Analysis: Analysis of time-based data to predict upcoming trends based on historical patterns. Useful for forecasting.
Survival Analysis: Estimates the expected lifetime of a subject based on existing longevity data.
Neural Networks: Systems modeled on the human brain intended to recognize patterns from complex data.
Classification Models: Assigns new data entries to specific categories based on historically labeled datasets. Enables predictive categorization.

How Does it Work?

The predictive analytics process has 5 main steps:

1. Define the Problem

The first step is to clearly define the problem you want to solve or the outcome you want to predict. For example, a retailer may want to forecast product demand during the holiday season, or a hospital may want to identify patients at risk of readmission. The more precisely you define the objective, the better, as it informs the data you’ll need and the type of predictive model you’ll build.

Common objectives include predicting customer churn, forecasting sales, estimating the risk of equipment failures, anticipating future demand levels, and projecting the likelihood of certain health outcomes.

2. Collect Relevant Data

Next, you’ll need to gather relevant historical and current data from all available sources, including company databases, sensors, web traffic logs, social media feeds, financial records, surveys, and more. The data collected should directly relate to the defined problem.

For the retailer forecasting holiday demand, past sales records, foot traffic data, web analytics, competitor pricing info, and economic indicators would all be useful. The more varied, high-quality data you can aggregate, the more accurate your model will become. Proper data collection and management is one of the most vital steps of the process.

3. Prepare the Data

Before data can be analyzed, it must be prepared through a process known as data wrangling. Preparation tasks include cleaning the data to fix errors, removing anomalies and outliers, handling missing values, transforming data formats for consolidation, and structuring the data for easy access by the predictive algorithms.

Proper data prep greatly minimizes “garbage in, garbage out” issues downstream. For the hospital readmissions example, patient records would need to be consolidated and standardized before analysis.

4. Build Predictive Models

With clean, integrated data in hand, data scientists can now develop and train predictive models using machine learning algorithms like regression analysis, decision trees, neural networks, and cluster analysis. The algorithms detect patterns and relationships within prepared historical datasets to make predictions about future events.

Multiple modeling techniques may be tested to find the one that most accurately maps inputs to outcomes for the defined problem. Models are evaluated and refined through rigorous testing procedures until optimal performance is achieved.

5. Test, Apply and Monitor the Model

Once a final model demonstrates reliable predictive accuracy, it can be deployed into production environments and applications. The hospital may embed their readmission risk model into patient screening software, while the retailer could auto-generate holiday demand forecasts.

After deployment, the model should be continuously monitored to ensure it keeps providing accurate predictions as new data flows through it. If performance drops, the model needs to be retrained on fresh data or rebuilt altogether. Automation and rapid retraining capabilities allow predictive apps to stay relevant over long periods.

Taking this structured approach helps ensure you build reliable, accurate predictive apps that deliver real business value.

Predictive Analytics Techniques

Various techniques are leveraged in predictive analytics to uncover patterns and generate accurate predictive insights. These include:

Data Mining

Data mining refers to the analysis of large sets of data to identify patterns and trends that can be used to make predictions. It employs sophisticated mathematical algorithms to segment the data and evaluate the probability of future events. Data mining is commonly used in predictive analytics to uncover correlations, associations, and relationships between variables that would otherwise remain hidden in large data sets.

For example, a retailer could use data mining to analyze its sales data to identify what products are frequently purchased together. This information can then be used to optimize product placements and promotions to increase sales. Data mining makes it possible to tap into big data to uncover insights that can drive competitive advantage.

Popular data mining techniques used in predictive analytics include classification, clustering, regression, association rules, decision trees, and neural networks. Data mining models can be descriptive, showing relationships between variables, or predictive, forecasting outcomes based on historical data patterns. The key benefit of data mining is in uncovering hidden correlations that provide actionable insights.

Machine Learning

Machine learning is the use of statistical algorithms that have the ability to “learn” from data without explicit programming. As opposed to hardcoded software, machine learning algorithms build models based on sample data to make predictions or decisions without being specifically told how. The algorithms “learn” by detecting patterns and relationships in data and using them to forecast future outcomes.

Machine learning drives many predictive analytics applications today. Two common categories of machine learning are supervised learning and unsupervised learning. In supervised learning, algorithms train on labeled example data, learning how to map input data to outputs. In unsupervised learning, algorithms must find patterns in unlabeled, unclassified data.

Machine learning powers a range of predictive analytics capabilities, including sentiment analysis, risk assessment, preventative maintenance, financial forecasting, healthcare predictions, media recommendations, and much more. As algorithms process more data, machine learning models become increasingly accurate, contributing to data-driven decision making processes across industries.

Text Analytics

Text analytics refers to techniques that analyze text data to extract insights. Unstructured text data is pervasive in various forms — documents, emails, social media posts, surveys, etc. — and contains valuable information about context, opinions, emotions, trends, and more. Text analytics leverages natural language processing (NLP) and analytical methods to transform unstructured text into quantified, actionable insights.

Sentiment analysis is an extremely useful text analytics technique for predictive analytics. It identifies the writer’s attitudes, feelings, opinions, etc. to determine emotional sentiment. Positive, negative, or neutral sentiments attached to brands, products, individuals, or topics can be a strong indicator of future behaviors. For example, analyzing customer feedback or social media conversations can signal rising dissatisfaction or potential reputation threats before they escalate.

Text analytics apply linguistic rules, machine learning, and statistical modeling to text data in order to categorize documents, extract keywords, recognize named entities, determine sentiment, identify themes, and more. The insights generated from analyzing unstructured text data can drive predictive analytics to forecast trends, behaviors, and events across industries.

Artificial Intelligence

Artificial Intelligence (AI) refers to computer systems that can perform tasks that typically require human intelligence and decision making abilities. AI tries to simulate elements of human cognition and logic in machines to drive automation and optimization. In predictive analytics, AI can detect subtle patterns and relationships in complex, multi-dimensional data that humans cannot easily identify.

There are two key capabilities of AI that power predictive analytics: machine learning and natural language processing (NLP). Machine learning algorithms “learn” from data, building models that predict new observations without explicit rules-based programming. NLP gives systems the ability to analyze, process and interpret human languages, including unstructured text data.

Together, AI’s machine learning and NLP capacities allow predictive analytics tools to process volumes of structured and unstructured data to uncover correlations, sentiments, and signals that would remain hidden to humans.

Predictive analytics applies techniques like regression modeling, decision trees, and neural networks to identify correlations and patterns in patient data. Factors examined include medical history, lab results, medications, demographics, family history, behaviors like smoking, and social determinants of health like education level and income.

These patterns are used to predict a patient’s risk of developing certain diseases like diabetes, hypertension, or cardiovascular disease. Predictions also diagnose conditions earlier and optimize treatments based on how similar patients responded. Providers can further identify patients prone to hospital readmission and mitigate risks through preventive care.

Banking – Predicting Credit Risks

Banks and financial institutions utilize predictive analytics on a massive scale to model, predict and mitigate risks. One major application is assessing credit risk, such as determining the probability that an individual loan applicant may default. Data scientists build predictive models using historical loan application data as well as credit bureau data.

The algorithms identify correlations between certain attributes of applicants and their tendency to default. These models consider factors like income levels, employment history, current debts, credit utilization ratio, payment histories, outstanding loans, as well as macroeconomic trends. Sophisticated machine learning techniques also uncover patterns among thousands of variables that may not be visible to the human eye but nevertheless predict credit risk.

Banks feed the unique data from new loan applicants into these credit risk models to classify them on a risk spectrum and make intelligent lending decisions accordingly. Predictive analytics augments human decision making to minimize exposure to bad loans. The models are also constantly monitored and re-developed as new data comes in, allowing improved assessment of risk over time. With such analytics, banks can continue prudent and sustained lending critical for economic growth.
