10. www.company.com What is Data Mining? Too much data and not enough information — this is a problem facing many businesses and industries. Most businesses have an enormous amount of data, with a great information hiding within it. Data mining provides a way to get the information buried in the data. Data mining creates models to find hidden patterns in large, complex collections of data. CPIT 440 Data Mining and Warehouse

11. www.company.com What is Data Mining in the database? Data mining projects usually require a significant amount of data collection and data processing. Real-world data is often dirty, which is, includes wrong or missing values, So, data must often be cleaned before it can be used. Data is filtered, normalized, sampled, transformed in various ways, and eventually used as input to data mining algorithms. Up to 80% of the effort in a data mining project is often devoted to data preparation. CPIT 440 Data Mining and Warehouse

12. www.company.com Oracle Data Mining (ODM) embeds data mining within the Oracle database. ODM algorithms operate natively on relational tables or views, thus eliminating the need to extract and transfer data into standalone tools or specialized analytic servers. ODM's integrated architecture results in a simpler, more reliable, and more efficient data management and analysis environment. CPIT 440 Data Mining and Warehouse What Is Oracle Data Mining?

13. www.company.com Data Mining Functions Data mining functions can be divided into following categories: –Supervised, Directed, Predictive functions –Unsupervised, Undirected, Descriptive functions CPIT 440 Data Mining and Warehouse

14. www.company.com Data Mining Functions Supervised data mining: –Classification: Assign items to predefined classes (categories). –Regression: Approximating and forecasting continuous values –Attribute Importance: Identifying the attributes that are most important in predicting results –Anomaly Detection: Identifying items that do not satisfy the characteristics of "normal" data (outliers) Unsupervised data mining: –Clustering: no predefined classes is required. The task is to find the grouping of the data based on the some relationships. –Association models: Analyzing "market baskets“, used to discover relationships or correlations in a set of items. –Feature extraction: Creating new attributes (features) as a combination of the original attributes.
