In data mining, anomaly detection (also outlier detection) is the identification of rare items, events or observations which raise suspicions by differing significantly from the majority of the data. Typically the anomalous items will translate to some kind of problem such as bank fraud, a structural defect, medical problems or errors in a text.. Anomalies are also referred to as outliers ...

Data Mining by Doug Alexander. dea@tracor . Data mining is a powerful new technology with great potential to help companies focus on the most important information in the data they have collected about the behavior of their customers and potential customers.
The mining industry is cyclical, thanks to the lag between investment decisions and new supply. Demand tends to grow in a relatively stable fashion on the back of global economic growth. By contrast, supply is added in bulk when a new development is completed. Figure 1: GDP growth (%) Source: IMF, PwC Analysis-4-2 0 2 4 6 8 10

Mining and geological engineers typically do the following: Design open-pit and underground mines; Supervise the construction of mine shafts and tunnels
Principal Business Activity Codes . This list of Principal Business Activities and their associated codes is designed to classify an enterprise by the type of activity in which it is engaged to facilitate the administration of the Internal Revenue Code.
A data mining process must be reliable and it must be repeatable by business people with little or no knowledge of data mining background. As the result, in 1990, a cross-industry standard process for data mining (CRISP-DM) first published after going through a lot of workshops, and contributions from over 300 organizations.
This course is an introduction to statistical data analysis. Topics are chosen from applied probability, sampling, estimation, hypothesis testing, linear regression, analysis of variance, categorical data analysis, and nonparametric statistics.
Predictive modeling uses statistics to predict outcomes. Most often the event one wants to predict is in the future, but predictive modelling can be applied to any type of unknown event, regardless of when it occurred. For example, predictive models are often used to detect crimes and identify suspects, after the crime has taken place.

In many parts of the world, artisanal or small-scale mining (ASM) activities are at least as important as large-scale mining activities, particularly in terms of the numbers of people employed. ASM can play a crucial role in poverty alleviation and rural development; most of those involved are poor and mining .
The difference between data analysis and data mining is that data analysis is used to test models and hypotheses on the dataset, e.g., analyzing the effectiveness of a marketing campaign, regardless of the amount of data; in contrast, data mining uses machine learning and statistical models to uncover clandestine or hidden patterns in a large ...
