What is Data Mining?

•Data mining is the process of discovering patterns, correlations, and insights


from large datasets.

•Uses machine learning, statistical, and database techniques.

•Helps in decision-making and predictive analysis.


Stages of Data Mining

• Data Collection – Gathering raw data from multiple sources.

• Data Preprocessing – Cleaning, transforming, and preparing data.

• Data Exploration – Understanding data through visualization and statistics.

• Pattern Discovery – Using algorithms to find trends and correlations.

• Evaluation & Interpretation – Analyzing and validating the discovered insights.

• Deployment – Applying insights to real-world applications.


Key Techniques in Data Mining

• Classification – Assigning labels to data (e.g., spam vs. non-spam emails).

• Clustering – Grouping similar data points (e.g., customer segmentation).

• Association Rule Mining – Finding relationships (e.g., Market Basket Analysis).

• Regression – Predicting numerical values (e.g., stock price prediction).

• Anomaly Detection – Identifying outliers (e.g., fraud detection).


Applications of Data Mining

• Business Intelligence: Customer behavior analysis, sales forecasting.

• Healthcare: Disease prediction, patient diagnosis.

• Fraud Detection: Identifying suspicious transactions in banking.

• Web & Social Media: Recommendation systems, sentiment analysis.

• Transportation: Traffic pattern analysis, route optimization.


Popular Tools for Data Mining

Python – Pandas, Scikit-learn R – Data analysis & visualization
