Data mining is a process of discovering patterns – usually relationships between variables, observations and events – by analyzing data. The term "data mining" was first used in the 1980s after the development of database systems required to manage "data warehouses" generated from relational databases. Data mining tools work by automating the discovery process, which involves using machine learning algorithms to uncover hidden trends and structures in large data sets.
Data Mining techniques can be categorized into two broad types: unsupervised and supervised.
In unsupervised methods, no target variable is specified so all the patterns are discovered purely based on correlations among input variables; otherwise known as exploratory analysis or prediscovery analysis . Commonly used approaches include clustering , association rule learning , regression/classification, density estimation and predictive data mining . Supervised methods require the target variable to be known or labeled. Common approaches include decision tree learning, artificial neural networks, logistic regression and support vector machines .
In addition to prediction of future values of target variables, data mining can also provide insight about past behavior. For example, an organization might wish to analyze its sales transactions in 2002 to develop a marketing plan for 2003. This includes analysis of whether customers purchased particular items together at the same time or within a short period of time after one another. It may discover that certain products are not selling as well as others and may adjust prices in order to improve profit margins or it may consider altering placement within stores or advertising campaigns in response to patterns observed.
Data used for data mining is often gathered from a variety of sources and processed to remove errors as part of the pre-processing, cleansing, integration, transformation or loading ( ETL ) phase before it can be analyzed by the data mining algorithms. Specialized software packages known as data mining tools have been developed which usually include tools for preprocessing, database connectivity and handling missing values among others in addition to providing features specifically aimed at improving effectiveness of pattern discovery and knowledge extraction. Data mining is advantageous because it allows researchers to formulate new hypotheses.
Information about certain events may help us understand why people shoplift as well as how retailers can reduce their losses from these thefts; information on employees' evaluations might provide employers with insight into their training programs or people's salaries could be used to predict how often they will change jobs; experience with a certain drug might help us understand its effectiveness and side effects.
Data mining techniques are also extensively employed in finance, marketing, fraud detection and prevention, counter-terrorism investigation , insurance, telecommunication and much more .

Data mining is a process of deriving actionable knowledge from the various datasets stored in databases. The purpose of data mining is to extract information from enormous amount of raw data (often called as Big Data ) and convert it into useful, meaningful information that can be utilized for decision making. This approach has been gaining popularity among companies throughout the world because it allows them to gain insight into their customers' perceptions , preferences etc . at a much more detailed level than was previously possible without incurring any additional costs or time associated with gathering such information .
For example , let's assume we want to use our sales data to predict customer likelihood of buying a certain product based on their previous purchases and salaries (both are considered as factors affecting purchasing decisions). A very simplistic model might look like this:
We can see that dummy variables are used to convert non-numerical factors into real numbers. In practice, we would do it like this:
Categorical variables are usually represented as either 0 or 1 (or sometimes omitted completely) and their effect on other relationships within the dataset is negligible because either they have no effect at all (e.g . gender) or customers from one group behave in a very similar fashion to those from another group (e.g . customers whose ages fall into different ranges). However , when transforming categorical variables into numeric ones during data mining , one should always use dummy variable s instead of simply assigning the value 1 to every member of that category and 0 for everyone else . That's because a categorical variable is treated as an independent factor by statistical models if it is numeric (e.g . gender) but including dummy variables into such model will make it dependent on values from other factors included in the model ( e . g . income). Since some users might have income=0, which would lead us to conclude that there was somehow no connection between their income and the likelihood of buying our product when compared to other customers , which clearly isn't true based on our hypothesis.
The wide range of algorithms used in data mining , combined with the high level of subjectivity present during this process makes it very important to run several algorithms and use different parameter settings for each one of them while trying to achieve optimum results. In fact , this is a very common practice among professional data miners , which allows them to utilize all available information collected during the modeling process . So if you want to get an A on your data mining assignment, make sure you have at least 2 (if not more) predictive models ready ! However , be aware that implementing multiple algorithms on a single dataset can sometimes result in overfitting , especially if you're using decision trees .
Overfitting denotes using too many input variables (as well as any other factors affecting statistical relationships within the model ) resulting in prediction error increasing rather than decreasing after training has finished. This happens because an overly complex/sophisticated model is unable to use the information it has acquired during the training process . This happens especially if one is using a single algorithm with many parameters and only small amount of data used for mining (a common mistake among students trying to complete their homework on time).
As you can see, a lot goes into modeling and even more when creating multiple models which are needed in practice. So make sure you spend enough time reading up on different aspects of data mining or by asking your professor or fellow students to help you with concepts that aren't as intuitive at first as they seem.
