Study Notes
Data Mining and Its Importance
- Data mining is a process for discovering patterns, models, and knowledge from vast datasets.
- Data mining addresses the need to analyze and extract meaningful information from the immense volume of data generated in today's world.
Understanding Data Types
- Data can be categorized as structured or unstructured based on its organizational structure.
- Structured data has a defined format and organization, such as relational databases or data warehouses.
- Unstructured data lacks a predefined format, such as text documents, images, or videos.
- Semi-structured data lies between these two extremes, having some organizational structure but not as rigid as structured data.
Machine Learning and Data Mining
- Machine learning is a field that teaches computers to learn and improve their performance based on data.
- Supervised learning involves training a model on labeled data to make predictions on new, unseen data.
- Unsupervised learning involves identifying patterns and structures in unlabeled data without prior knowledge.
Data Mining in Business Intelligence
- Business intelligence (BI) tools use data mining to provide insights and predictions for business operations.
- Applications include reporting, online analytical processing, and predictive analytics.
- Data mining is essential for market analysis, customer feedback, and strategic business decisions.
Data Mining in Web Search Engines
- Web search engines rely heavily on data mining to handle massive, ever-growing datasets.
- They face challenges in processing vast amounts of data, often distributed across multiple machines.
- Scaling up data mining methods on distributed systems is a critical area of research.
- Web search engines also deal with online data streams, requiring real-time data mining capabilities.
