Study Notes
Data Mining
- Data mining is a process to discover or mine knowledge from large amounts of data to develop intelligence.
- It involves identifying valid, novel, potentially useful, and ultimately understandable patterns in data stored in structured databases.
Applications of Data Mining
- Detecting diabetes
- Intelligent Transportation System
- Handwritten digit recognition
- Speech emotion recognition
- Music recommendation system
- Detecting suicidal tendency
- Gender age detection
- Driver drowsiness detection
- American Honda uses advanced analytics to improve warranty claims
- Eyeglasses Facial Recognition to analyze emotions and feelings
Data Mining Tasks
- Visualization: integrates with other data mining techniques to see underlying relationships
- Time-series forecasting: part of sequence or link analysis, involves analyzing data that consists of values of the same variable stored over time in regular intervals
Types of Data Mining
- Hypothesis-driven data mining
- Discovery-driven data mining
Data Mining Process
- A systematic project management process is essential for a successful data mining project
- Common standard processes: CRISP-DM, SEMMA, KDD
- CRISP-DM process:
- Business Understanding
- Data Understanding
- Data Preparation
- Model Building
- Testing and Evaluation
- Deployment
- Data preparation is a critical task that accounts for ~85% of total project time
- Data preparation involves:
- Data Consolidation
- Data Cleaning
- Data Transformation
- Data Reduction
- Producing well-formed data
Association Rule Mining
- Used to find objects that occur together
- Finds interesting relationships (affinities) between variables (items or events)
- Also known as market basket analysis
- Example: customers who bought a laptop and virus protection software also bought an extended service plan 70% of the time
