What is regression?
What is regression?
Regression is a statistical technique used to find a relationship between a dependent variable (target) and one or more independent variables (predictors). It helps predict outcomes or the probability of a variable based on other factors.
How is regression used in healthcare?
How is regression used in healthcare?
Regression can predict patient outcomes based on treatment plans. For example, it can forecast how patients will respond to different therapies, helping doctors personalize care.
What is outlier detection?
What is outlier detection?
Outlier detection identifies data points that significantly deviate from the rest of a dataset. It helps uncover abnormalities and take appropriate actions.

Study Notes
BMT 342 Data Mining in IoT/IoMT - Lecture 8
- Course: BMT 342 Data Mining in IoT/IoMT
- Lecture: 8
- Instructor: Dr. Asma Abahussin
- Department: Department of Biomedical Technology, College of Applied Medical Sciences, King Saud University
Objectives
- Understand what data mining is
- Learn the importance of data mining
- Understand data mining techniques
Introduction
- IoT/IoMT systems generate substantial raw data
- Business owners need data-driven decision-making
- Data mining is crucial for extracting maximum value from data and creating strategic business decisions
What is Data Mining?
- Data mining is a subset of data science
- Focuses on discovering patterns and key information from large datasets.
- Relies on machine learning & statistical analysis
Data Mining Techniques
-
Classification:
- Divides data into predefined categories based on relevant information
- Useful in building predictive models
- Examples: Disease diagnosis, patient risk assessment
-
Clustering:
- Groups data points with similar characteristics into clusters
- Helps identify hidden patterns
- Examples: Patient segmentation, disease patterns
-
Regression:
- Establishes relationships between dependent (target) and independent (predictor) variables
- Useful for predicting outcomes or defining probabilities based on factors.
- Examples: Predicting treatment outcomes, resource utilization
-
Outlier Detection:
- Identifies data points significantly different from the rest of the dataset
- Helps detect anomalies and take appropriate actions
- Example: Unusual patient data monitoring (vital signs)
Are All the Patterns Interesting?
- Data mining can generate many patterns, but not all are valuable
- A pattern is considered interesting if it's:
- Novel (new)
- Potentially useful
- Valid on new or test data
- Interesting patterns are instrumental in driving decisions.
