Though data models can be complex, they can also yield fascinating results, unearth hidden trends, and suggest unique strategies.You might find eBay to be the platform of choice if you’re looking to start a business with minimal capital and a broad reach. This benefit of data mining allows a company to create value with the information they have on hand that would otherwise not be overly apparent. The end goal of data mining is to take raw bits of information and determine if there is cohesion or correlation among the data.Essentially any type of data can be gathered and analyzed, and almost every business problem that relies on qualifiable evidence can be tackled using data mining. Data mining can look very different across applications, but the overall process can be used with almost any new or legacy application.Therefore, data mining helps a business become more profitable, more efficient, or operationally stronger. It is often a more rigid, structured process that formally identifies a problem, gathers data related to the problem, and strives to formulate a solution. Data mining ensures a company is collecting and analyzing reliable data.Overlapping with regression analysis, this technique aims at supporting an unknown figure in the future based on current data on hand. Predictive analysis strives to leverage historical information to build graphical or mathematical models to forecast future outcomes. This model can be programmed to give threshold values to determine a model's accuracy. Data is mapped through supervised learning, similar to the ways in which the human brain is interconnected. These nodes are comprised of inputs, weights, and an output. Neural networks process data through the use of nodes.This non-parametric, supervised technique is used to predict the features of a group based on individual data points. The basis for KNN is rooted in the assumption that data points that are close to each other are more similar to each other than other bits of data. K-Nearest neighbor (KNN) is an algorithm that classifies data based on its proximity to other data.Sometimes depicted as a tree-like visual, a decision tree allows for specific direction and user input when drilling deeper into the data. A decision tree is used to ask for the input of a series of cascading questions that sort the dataset based on the responses given. Decision trees are used to classify or predict an outcome based on a set list of criteria or decisions.While classification may result in groups such as "shampoo," "conditioner," "soap," and "toothpaste," clustering may identify groups such as "hair care" and "dental health." However, clustering identifies similarities between objects, then groups those items based on what makes them different from other items. Clustering is similar to classification.This data mining technique allows the underlying data to be more neatly categorized and summarized across similar features or product lines. These classes describe the characteristics of items or represent what the data points have in common with each. Classification uses predefined classes to assign to objects. For example, association rules would search a company's sales history to see which products are most commonly purchased together with this information, stores can plan, promote, and forecast. This relationship in itself creates additional value within the data set as it strives to link pieces of data.
