Menu Top 5 Data Mining Techniques Are you starving to gain insights from big data, but not sure what data mining techniques to use? Priyanka SharmaSeptember 8, Download Each of the following data mining techniques cater to a different business problem and provides a different insight. The ironic fact is, we are drowning in data but starving for knowledge.
Each type of analysis will have a different impact or result. The data mining technique you should use, depends on the kind of business problem that you are trying to solve.
Different analyses will deliver different outcomes and thus provide different insights. One of the common ways to recover valuable insights is via the process of data mining.
Each of the following data mining techniques cater to a different business problem and provides a different insight. Knowing the type of business problem that you’re trying to solve, will determine the type of data mining technique that will yield the best results. DATA MINING TECHNIQUES. Over the years, as the concept of data mining evolved, and technology has become more advanced, more and more techniques and tools were introduced to facilitate the process of data analysis. Data Mining Tools and Techniques Understanding the advantages of using different data mining tools and techniques — and knowing what data mining does — can help beginner auditors provide recommendations that improve business processes and discover fraud.

This, however, is too broad as data mining refers to the discovery of previously unknown patterns, unusual records or dependencies.
When developing your big data strategyit is important to Data mining techniques a clear understanding of what data mining is and how it can help you. The most important objective of any data mining process is to find useful information that is easily understood in large data sets. There are a few important classes of tasks that are involved with data mining: Anomaly or Outlier Detection Anomaly detection refers to the search for data items in a dataset that do not match a projected pattern or expected behaviour.
Anomalies are also called outliers, exceptions, surprises or contaminants and they often provide critical and actionable information. An outlier is an object that deviates significantly from the general average within a dataset or a combination of data.
It is numerically distant from the rest of the data and, therefore, the outlier indicates that something is out of the ordinary and requires additional analysis.
It can help to find extraordinary occurrences that could indicate fraudulent actions, flawed procedures or areas where a certain theory is invalid. Important to note is that in large datasets, a few outliers are common. Outliers may indicate bad data but may also be due to random variation or may indicate something scientifically interesting.
In all cases, additional research is required.
Association Rule Learning Association rule learning enables the discovery of interesting relations interdependencies between different variables in large databases. Association rule learning uncovers hidden patterns in the data that can be used to identify variables within the data and the co-occurrences of different variables that appear with the greatest frequencies.
Association rule learning is often used in the retail industry when to find patterns in point-of-sales data. These patterns can be used when recommending new products to others based on what others have bought before or based on which products are bought together.
If this is done correctly, it can help organisations increase their conversion rate. Thanks to data mining, Walmart, already indiscovered that Strawberry Pop-tarts sales increased by seven times before a hurricane. Since this discovery, Walmart places the Strawberry Pop-Tarts at the checkouts before a hurricane is about to happen.
Clustering Analysis Clustering analysis is the process of identifying data sets that are similar to each other, to understand the differences as well as similarities within the data.
Clusters have certain traits in common that can be used to improve targeting algorithms. For example, clusters of customers with similar buying behaviour can be targeted with similar products and services to increase the conversation rate. A result from a clustering analysis can be the creation of personas.
The programming language R has a large variety of functions to perform relevant cluster analysis and is therefore especially relevant for performing a clustering analysis. Classification Analysis Classification Analysis is a systematic process for obtaining important and relevant information about data, and metadata - data about data.
The classification analysis helps to identify the categories the data belongs. Classification analysis is closely linked to cluster analysis as the classification can be used to cluster data. Your email provider performs a well-known example of classification analysis: This is done based on data that is linked with the email or the information that is in the email, for example, certain words or attachments that indicate spam.
Regression Analysis Regression analysis tries to define the dependency between variables. It assumes a one-way causal effect from one variable to the response of another variable. Independent variables can be affected by each other, but it does not mean that this dependency is both ways as is the case with correlation analysis.
A regression analysis can show that one variable is dependent on another but not vice-versa. A more concrete example is that a regression analysis can help you find the love of your life on an online dating website. Data mining can help organisations and scientists to find and select the most important and relevant information.
This information can be used to create models that enable predictions how people or systems will behave so you can anticipate on it. The more data you have, the better the models will become that you can create using the data mining techniques, resulting in more business value for your organisation.DATA MINING TECHNIQUES.
Over the years, as the concept of data mining evolved, and technology has become more advanced, more and more techniques and tools were introduced to facilitate the process of data analysis.
Different data mining techniques can help organisations and scientists to find and select the most important and relevant information to create more value.
Big data caused an explosion in the use of more extensive data mining techniques, partially because the size of the information is much larger and because the information tends to be more varied and extensive in its very nature and content.
Sep 16, · Data mining techniques are set of algorithms intended to find the hidden knowledge from the data. Usage of data mining techniques will purely depend on the problem we were going to solve. Some of the popular data mining techniques are classification algorithms, prediction analysis algorithms, clustering techniques.
Each of the following data mining techniques cater to a different business problem and provides a different insight. Knowing the type of business problem that you’re trying to solve, will determine the type of data mining technique that will yield the best results.
