Data Mining - ANSWERData Mining is the exploration and analysis of
large quantities of data in order to discover
meaningful patterns and rules
Data mining is the process of - ANSWERusing "raw" data to
infer important "business" relationships
Data Mining is a collection of - ANSWERpowerful techniques intended for analyzing
large
amounts of data
the approach of data mining - ANSWERThere is no single data mining approach, but
rather a set of techniques that can be used stand
alone or in combination with each other
why data mining - ANSWERMore data is being generated
Data is being warehoused
Computing power is affordable
Competitive pressure is strong
Need to leverage IS for competitive advantage
Commercial data mining software products
are available
In the early 1960s, data mining was called - ANSWERstatistical analysis
By the late 1980s, the traditional techniques - ANSWERhad been augmented by new
methods such
as fuzzy logic, heuristics and neural networks
data warehouse - ANSWERa copy of transaction data specifically structured for
querying, analysis and reporting
things to notice about data warehouse - ANSWERcontains a copy of the transactions
which are not
updated or changed later by the transaction
system
data is specially structured, and may have been transformed when it was copied into
the data warehouse
Data Mart - ANSWERis a smaller, more focused Data
Warehouse

A Data Mart typically reflects - ANSWERthe business rules of a specific business unit within an enterprise what is the hierarchy of warehouse and data mart - ANSWERdata warehouse->data mart->decision support info two types of data mining - ANSWERDirected -Attempts to explain or categorize some particular target field such as income or response Undirected -Attempts to find patterns or similarities among groups of records without the use of a particular target field or collection of predefined classes cycle of data mining - ANSWERidentify business problems->data mining->act on info-

measure the results data mining tasks - ANSWERClassification Estimation Prediction Affinity Grouping Clustering classification - ANSWERExamining features of an object and assigning it to one of a predefined set of classes (need to be well defined) Classifier model may be built using - ANSWERa training set of preclassified objects examples of classification - ANSWERCharacter recognition Assigning loan applications into {approve, deny, incomplete, seek more information}

Determine gender based on age and movies seen data mining methods for classification - ANSWERDecision trees, pattern recognition, memory-based reasoning, link analysis Estimation - ANSWERGenerate an output value based on a set of input quantities is estimation similar to classification - ANSWERYes, and also may be "trained," but deals with a range of output values
