What is predictive analytics?
Predictive analytics aims to answer “what might happen next?”
It combines statistical algorithms, data analysis, and machine learning to build precise and accurate models that predict future outcomes.
These models look at historical data, identifying patterns, trends, and relationships to anticipate what could happen. This information helps forecast events and behavior, such as sales estimates, campaign engagement, and churn prediction, enabling businesses to optimize their strategies.
It’s a data-backed way for businesses to predict the future—an essential tool for any organization.
How does predictive analytics work?
Predictive analytics uses historical data to build models that anticipate the future.
The accuracy and usefulness of these predictions rely on the data quality, model choice, and how well the deployed model is monitored and maintained.
Let’s break down precisely how it works:
- Data collection: The process begins with collecting data from various sources. The data should represent the problem you’re trying to solve and include the input variables (features) and the target variable (the outcome you want to predict).
- For example, if you’re creating a customer churn prediction model, the target variable would be if they canceled their subscription, and the input variables would be things like usage metrics, engagement data, customer feedback, etc. You’d need this data to predict the likelihood of a customer churning from the service.
- Data cleaning and preparation: Once collected, the data is cleaned, organized, and preprocessed. This could include filling in missing values, handling outliers, and converting data into a consistent format. Clean and well-prepared data is essential for accurate model training, so this step is vital.
- Feature selection and engineering: Feature selection identifies the most relevant variables that will have a meaningful impact on the prediction. You might need to create new variables based on existing ones to capture more complex relationships or insights.
- Consider a fraud detection model for online transactions. Instead of using raw transaction amounts as a feature, you could create a “transaction velocity” variable by dividing the amount by the time since the last transaction to capture unusual or rapid patterns. Try not to include unnecessary or redundant features that could make “noise”.
- Model selection: You can apply different predictive models based on the nature of the problem and the data. The one you choose depends on the complexity of the problem, the amount of data available, and the interpretability of the model.
- Model training: In this step, historical data is divided into two parts—a training dataset and a validation dataset. The training dataset teaches the model to learn the patterns and relationships between the input variables and target outcomes. The model adjusts its internal parameters during training to minimize prediction errors.
- Model evaluation: You’ll use the validation dataset to evaluate the trained model’s performance. The model makes predictions on the validation data, and its predictions are compared with the actual outcomes to assess its accuracy.
- Model tuning: The model might need adjustments based on the evaluation results. This process is called hyperparameter tuning, where you finetune the model’s parameters to improve its performance.
- Model deployment: Once the model is trained and validated, it’s ready for deployment. It can now make predictions on new, unseen data. Deployment happens in various ways, depending on the application. The model could be integrated into an application, website, or automated process.
- Monitoring and maintenance: It’s best to monitor predictive models to ensure they remain accurate. As new data becomes available, the model might need periodic updates or retraining to adapt to changing patterns.
Benefits of predictive analytics
Knowing what could happen in the future is incredibly empowering. When businesses can access more accurate predictions, they make more data-driven decisions to minimize risks and capitalize on opportunities. A precise predictive model is key to making this happen.
Let’s explore these benefits in more detail.
Predict and prepare for change
Predictive analytics enables organizations to anticipate industry, market, or customer behavior changes.
By identifying trends and patterns in historical data, businesses can make more accurate predictions about shifts in demand, preferences, or market conditions. This contributes to proactive decision-making and strategic planning to adapt to upcoming changes.
Plan for potential futures
Businesses can use predictive analytics to simulate different scenarios and outcomes based on data-backed insights. This helps them create contingency plans and strategies to mitigate risks and take advantage of opportunities.
Organizations can make more informed choices and improve their long-term planning by understanding the potential outcomes of different decisions.
Analyze and anticipate behavior
Predictive customer analytics enables businesses to understand user behavior, preferences, and actions more deeply.
By analyzing historical customer data, companies can predict future behaviors, such as purchasing trends, engagement patterns, and churn likelihood. This information is invaluable for tailoring marketing strategies, improving customer experiences, and retaining valuable customers.
Applying predictive analytics enhances operational efficiency by optimizing processes and resource allocation.
It can help predict manufacturing equipment maintenance needs, optimize supply chain logistics, and predict employee attrition to enhance workforce management.
By spotting inefficiencies and bottlenecks, businesses can streamline operations and reduce costs.
Challenges of predictive analytics and how to overcome them
Predictive analytics is a complex process that, despite its many benefits, can present some challenges during implementation.
Addressing these blockades and understanding how to overcome them results in an effective and successful predictive analytics initiative.
- Data quality and availability: Predictive analytics relies on clean, accurate, and relevant data. As well as data cleaning and preprocessing, it’s recommended to implement data quality checks, validation processes, and governance strategies.
- Model overfitting: Overfitting happens when a predictive model is too closely tailored to training data and performs poorly on new, unseen data. This leads to inaccurate predictions. To overcome this, validate models on independent datasets to ensure they generalize well, using techniques like cross-validation and regularization.
- Lack of domain expertise: Building accurate predictive models needs a deep understanding of the domain and relevant factors influencing the outcome. To make the models more accurate and relevant, collaborate with experts who can provide insights into the relationships between variables and guide the feature selection process.
- Changing patterns and dynamics: Markets and behaviors evolve over time, meaning that models trained on historical data may become less accurate if these patterns shift. Ensure to retrain and update predictive models with new data regularly, implement mechanisms to monitor model performance, and trigger updates when changes happen.
- Interpretability and explainability: Complex predictive models can be tricky to interpret, making explaining why they made certain predictions challenging. Choose models that balance accuracy and interpretability, using different techniques to help explain model predictions.
- Resource constraints: Implementing predictive analytics sometimes requires specialized skills, tools, and resources, which can be a barrier. Consider using platforms or outsourcing parts of the process to experienced providers so you can focus on building internal knowledge gradually.
Predictive analytics: models and techniques
There are various techniques, algorithms, and mathematical processes you can use to apply predictive analytics. Deciding which predictive models are best for your organization is crucial for getting the most out of your predictive analytics strategy.
The same predictive analytics models might not serve businesses in different industries. For example, a healthcare provider predicting patient readmissions will need a different approach than an ecommerce platform optimizing its product recommendations. Their unique contexts and needs demand differing predictive analytics.
Each model has its strengths and applications—in predictive analytics, more complex doesn’t always mean better.
Straightforward models and techniques help guide decisive action, while emerging technologies can offer a level of insight previously unknown.
To help you choose, let’s uncover some of the most popular approaches.
Decision trees are step-by-step guides for making decisions. They help break down complex choices into manageable steps to help businesses reach informed conclusions.
Decision trees use “if/then” scenarios, where you start with the main question and then make choices depending on the answers. The result is a tree-like structure of decisions you can use to make predictions.
Decision trees are usually applied in classification and regression tasks. Some scenarios appropriate for decision trees include:
- Looking at usage patterns and customer service interaction to find high-churn-risk customers.
- Analyzing product preference or browsing history to provide product recommendations.
- Exploring patient symptoms and medical history to help doctors reach a diagnosis.
- Answering customer’s frequently asked questions.
- Routing tickets to appropriate departments.
Data mining helps businesses find patterns, trends, and relationships from lots of information. It’s an umbrella term that covers several techniques, such as:
- Clustering—grouping similar things together
- Association rule mining—spotting interesting connections
- Anomaly detection—finding unusual things that stand out
Application examples include:
- Finding patterns in what people bought to recommend what they might like
- Spot unusual patterns in credit card transactions to recognize fraudulent activity
- Optimizing social media feeds based on what users have previously engaged with.
Regression analysis is a common business scenario where you use mathematical analysis to determine which variables or inputs will have an impact on the outcome. For instance, predicting which promotions (your inputs) will most impact your sales conversions (the outcome).
Linear regression is one approach. It models the relationship between the independent and dependent variables using a linear equation, like drawing a straight line through points on a graph to show how changes in one thing lead to changes in another.
Some other use cases include:
- Giving you the formula to estimate house prices by seeing how certain features can affect its value.
- Understanding if increasing ad spending leads to a proportionate increase in sales, or if it’s down to other factors.
Businesses use clustering to put similar things together based on their features or other like criteria. Cohort segmentation and analysis use this predictive analytics model.
They can use it to:
- Segment customers or users
- Analyze different markets after grouping areas
- Review customer feedback by linking reviews with similar words or topics.
While not a predictive analytics technique itself, data warehousing is crucial for its success.
It gathers data from different places and stores and organizes it in a centralized repository, making it easier to find and use when making predictions.
Neural networks are a subset of machine learning algorithms inspired by the structure of the human brain. For instance, if you think to yourself, “I’m warm!” This is your brain subconsciously processing this sensation from a network of connected neurons that communicate and signal to each other. Neural networks function similarly. They contain interconnected layers of nodes (neurons) that process and learn from data.
There are different types of neural networks—convolutional neural networks (CNNs) are good for understanding pictures, while recurrent neural networks (RNNs) are better at determining what a sentence means. Each helps improve machine learning models by enabling them to learn and understand complex tasks.
AI in predictive analytics covers several techniques and technologies, including machine learning and deep learning.
It’s used to build systems that can learn from data, reason over it, and make decisions or predictions autonomously.
