This tutorial will teach you basic Android programming and will also take you through some advance Advanced Andr Download Android Tutorial (PDF. A Data Mining Tutorial. Presented at the Second IASTED International Conference on Parallel and Distributed Computing and Networks. Data Mining is defined as extracting the information from the huge set of data. ppti.info or this tutorial may not be redistributed or reproduced in any.
For instance, name of the customer is different in different tables. Data transformation operations change the data to make it useful in data mining.
Following transformation can be applied Data transformation: Data transformation operations would contribute toward the success of the mining process.
Smoothing: It helps to remove noise from the data. Aggregation: Summary or aggregation operations are applied to the data. Generalization: In this step, Low-level data is replaced by higher-level concepts with the help of concept hierarchies.
For example, the city is replaced by the county. Normalization: Normalization performed when the attribute data are scaled up o scaled down. Example: Data should fall in the range Attribute construction: these attributes are constructed and included the given set of attributes helpful for data mining. The result of this process is a final data set that can be used in modeling.
Modelling In this phase, mathematical models are used to determine data patterns. Based on the business objectives, suitable modeling techniques should be selected for the prepared dataset.
Create a scenario to test check the quality and validity of the model. Run the model on the prepared dataset.
Results should be assessed by all stakeholders to make sure that model can meet data mining objectives. Evaluation: In this phase, patterns identified are evaluated against the business objectives.
Results generated by the data mining model should be evaluated against the business objectives. Gaining business understanding is an iterative process. In fact, while understanding, new business requirements may be raised because of data mining. A go or no-go decision is taken to move the model in the deployment phase. Deployment: In the deployment phase, you ship your data mining discoveries to everyday business operations.
The knowledge or information discovered during data mining process should be made easy to understand for non-technical stakeholders. A detailed deployment plan, for shipping, maintenance, and monitoring of data mining discoveries is created.
A final project report is created with lessons learned and key experiences during the project.
This helps to improve the organization's business policy. Data Mining Techniques 1. Classification: This analysis is used to retrieve important and relevant information about data, and metadata.
This data mining method helps to classify data in different classes. Clustering: Clustering analysis is a data mining technique to identify data that are like each other. This process helps to understand the differences and similarities between the data. Regression: Regression analysis is the data mining method of identifying and analyzing the relationship between variables.
It is used to identify the likelihood of a specific variable, given the presence of other variables. Association Rules: This data mining technique helps to find the association between two or more Items.
It discovers a hidden pattern in the data set. Outer detection: This type of data mining technique refers to observation of data items in the dataset which do not match an expected pattern or expected behavior.
This technique can be used in a variety of domains, such as intrusion, detection, fraud or fault detection, etc. Outer detection is also called Outlier Analysis or Outlier mining.
Sequential Patterns: This data mining technique helps to discover or identify similar patterns or trends in transaction data for certain period. Prediction: Prediction has used a combination of the other data mining techniques like trends, sequential patterns, clustering, classification, etc.
It analyzes past events or instances in a right sequence for predicting a future event. Challenges of Implementation of Data mine: Skilled Experts are needed to formulate the data mining queries.
