Data mining is a foundation for predictive analysis, allowing the extraction of patterns from large datasets to forecast outcomes. In a healthcare setting, it can be applied to cybersecurity procedures to identify unusual patterns in the system that may not be evident through traditional security measures.
The concepts
Data mining
Data mining is the process of analyzing vast amounts of data to discover patterns, correlations, and anomalies that can inform decision-making. The process makes use of various steps to analyze data including:
- Data collection
- Preparation
- Transformation
- Mining
- Evaluation
Predictive analytics
Predictive analytics builds upon the findings of data mining by applying statistical algorithms and machine learning techniques to forecast future events based on historical data. While data mining deals with discovering patterns in existing data, predictive analytics takes those patterns and uses them to make informed predictions about what might happen in the future.
How data mining for predictive analytics works
- The process begins by defining the goals of the predictive analysis including specific outcomes that are being predicted and what questions need to be answered.
- Relevant data is gathered from various sources like historical records and real-time data streams. The data can include structured data (like numerical values) and unstructured data (like text or images).
- The collected data is cleaned to remove inaccuracies and irrelevant information.
- Analytics explore the cleaned data to identify patterns, trends, and relationships.
- Relevant features (variables) are selected based on their relevance to the prediction task.
- Various predictive models are developed using machine learning algorithms like regression analysis, decision trees, or neural networks.
- The selected model is trained using a portion of the dataset (the training set) to learn patterns and relationships within the data.
- The model’s performance is evaluated using a separate portion of the dataset (the testing set) to make sure it can accurately predict outcomes on unseen data.
- Once validated, the predictive model is deployed into the production environment where it can be used to make real-time predictions based on new incoming data.
How it can be used in email security
A journal article from the Library Progress International provides, “In 2019, a staggering 88% of phishing emails were processed through big data engines, underscoring the magnitude of the challenge faced.” With the use of data mining for predictive analysis threats like phishing threats are proactively identified and mitigated. The process begins with the collection of vast amounts of email data including historical patterns of legitimate and malicious emails.
Methods of data mining like clustering and classification allow organizations to analyze these datasets to uncover patterns that distinguish phishing attempts from genuine communications. An example of this is data mining revealing common characteristics of phishing emails like specific keywords.
Once these patterns are identified, predictive analytics can be applied to develop models that assess the chances of an incoming email being a phishing attempt based on its features. Machine learning algorithms can continuously learn from new data, improving their ability to detect changes in phishing tactics over time.
FAQs
What is the function of machine learning?
A subset of AI focused on developing algorithms that allow computers to learn from and make predictions or decisions based on data.
What is the predictive analysis process cycle?
- Problem definition
- Data collection
- Data preparation
- Exploratory data analytics
- Model development
- Model testing and validation
- Deployment
What is the difference between clustering and classification methods of data mining?
Clustering is an unsupervised learning technique that groups data points based on their similarities without predefined labels. Classification, on the other hand, is a supervised technique that assigns predefined labels to data points based on their attributes.
