Study Notes
Data Mining Techniques
- Association techniques are used to find attributes that "go together" and quantify relationships between two or more attributes.
- Common applications of association techniques include affinity analysis and market basket analysis in the business world.
Anomaly Detection
- Anomaly detection is also referred to as outlier detection or analysis.
- It involves identifying data objects that do not comply with the general behavior or model of the data.
- A common use case is detecting fraudulent credit card transactions by identifying unusually large purchases.
Data Mining Techniques Overview
- Classification involves predicting a categorical label or class.
- Prediction involves predicting a continuous value or range.
- Regression involves predicting a continuous value or range using a linear model.
- Association involves finding attributes that "go together".
- Clustering involves grouping similar data objects together.
- Anomaly detection involves identifying outliers or unusual data objects.
Data Mining Examples
- Dividing customers by gender or profitability is not a data mining task, as it involves simple database queries or accounting calculations.
- Predicting the profitability of a new customer is a data mining task.
- Computing total sales of a company is not a data mining task, as it involves simple accounting.
- Sorting a student database by student identification numbers is not a data mining task, as it involves a simple database query.
- Predicting the outcomes of tossing a fair pair of dice is not a data mining task, as it involves probability calculations.
- Predicting the future stock price of a company using historical records is a data mining task, an example of predictive modeling.
- Monitoring the heart rate of a patient for abnormalities is a data mining task, an example of anomaly detection.
- Monitoring seismic waves for earthquake activities is a data mining task, an example of classification.
Machine Learning
- Machine learning is a method of data analysis that automates analytical model building.
- It is a branch of artificial intelligence (AI) that allows systems to learn from data, identify patterns, and make decisions with minimal human intervention.
- Machine learning focuses on developing computer programs that can access data and use it to learn for themselves.
Traditional Programming vs Machine Learning
- Traditional programming involves writing explicit rules to achieve a specific output.
- Machine learning involves training a model on data to learn patterns and make decisions.
Machine Learning Process
- The process of learning begins with observations or data, such as examples, direct experience, or instruction.
- The goal is to look for patterns in the data and make decisions or predictions based on those patterns.
