Data Mining is the process of considering at large banks of information to generate new information. It is the procedure of finding variances, patterns and correlations within huge data sets to forecast outcomes [1]. You can think that data mining refers to the extraction of new data, but this is not the case; instead, it is about generalizing patterns and new information from the data you have already collected.

Why is Data Mining Important?

You might have seen the volume of data formed in every 2 years is almost double. This does not mean that with more data you got more knowledge. To get more insights of the data you collected data mining helps you in many ways. Such as it allows you to:

  • Examine through all the disordered and repetitive noise in your data.
  • Recognize what is relevant and then make good use of that information to assess probable outcomes.
  • Fast-track the pace of making knowledgeable decisions.
Data Mining Importance

Depending on techniques and technologies from the intersection of database management, statistics, and machine learning, experts in data mining have devoted their careers to enhanced understanding how to practice and draw inferences from enormous amounts of information. But what are the techniques they use to make this happen?

Data Mining Techniques

Data mining is extremely effective, so long as it draws upon one or more of these techniques:

data mining techniques
  1. Tracking Patterns: One of the most elementary techniques in data mining is learning to identify patterns in your data sets. This is typically recognition of some deviation in your data happening at consistent intervals, or an ebb and flow of a particular variable over time. For example, data mining helps in inferring patterns in raw data that is produced by the internet browsing patterns of the customers.  

  2. Classification: Classification is another useful data mining technique that forces you to collect various attributes together into distinct groups, which you can then use to draw additional conclusions, or aid certain function. For example, if you are evaluating data on different customers’ monetary backgrounds and buying histories, you might be able to categorize them as “low,” “medium,” or “high” credit risks. You could then use these categorizations to study even extra about those clients.

  3. Association: Association is related to tracking patterns, but is more specific to dependently linked variables. In this, you will look for particular events or characteristics that are highly correlated with another event or attribute. For example, you might notice that when your customers purchase a particular item, they also frequently purchase a second, related item. This is typically what is used to populate “people also bought” segments of online stores.

  4. Outlier Detection: In numerous cases, just recognizing the primary pattern can’t give you a vibrant understanding of your data set. You also require being able to identify irregularities, or outliers in your data. For example, if your buyers are nearly entirely male, but during one odd week in August, there is a vast spike in female buyers, you want to examine the spike and see what gathered it, so you can either repeat it or better understand your audience in the procedure.

  5. Clustering: Clustering is quite similar to classification, but includes grouping chunks of data together based on their resemblances. For example, you might select to cluster different demographics of your audience into diverse packets based on how much nonrefundable income they have, or how repeatedly they tend to shop at your store.

  6. Regression: Regression is used mainly as a method of planning and modeling. It is used to recognize the likelihood of a particular variable, given the presence of other variables. For example, you could use it to project a particular price of an item, based on additional factors like availability, customer demand, and competition. More specifically, regression’s chief focus is to help you uncover the exact relationship between two or more variables in a given data set.

  7. Prediction: Prediction is one of the most cherished data mining techniques, as it is used to project the kinds of data you’ll get in the coming future. In several cases, just identifying and understanding past trends are sufficient to plan marginally accurate prediction of what will occur in the future. For example, you might review consumers’ credit histories and past buying to forecast whether they’ll be a credit risk in the future.
