Data always remains as raw until and unless it is being mined, and the information contained within it is harnessed. Mining data to make sense of it has applications in a wide range of academic and industry. In this article, we are now going to explore the best open source tools that can even aid us in the process of data mining.

There are lots of data mining tools that are available to use.

Data mining, which is also known by the name as knowledge discovery from the databases, is one of the essential processes of extraction and analyzing enormous amounts of data and extracting information from it. Data mining can quickly answer the business questions that would even have otherwise consumed a lot of time.

There are lots of data science latest news available on the Techiexpert.

Some of its applications include the market segmentation like the identifying characteristics of a customer buying of a particular product from a specific brand, fraud detection – identifying transaction patterns that could even probably result in online fraud, trend analysis 00 what products or services are always purchases together and market-based trend, etc.

This article focuses on the full range of open sources and paid options that are available and their significance in the different contexts.

For all those people, who are just new to data mining, let us take a brief look at some of the tasks which are common to data mining.

Pre-processing: This task provided with all the preliminary tasks that can help in getting started with any of the actual mining tasks. Pre-processing could be removing the anomalies and noise from the data that is about to be mined, filling in missing values, normalizing the data, or even compressing the data with the help of techniques like the aggregation and generalization.

Clustering: This is a partitioning with a massive set of data into the related subclasses.

Classification: This is a process of tagging or classifying data items into the different user-defined categories. Outlier analysis helps in the identification of those data elements, which are deviant or distant from the rest of the ingredients in a dataset. This can even help in anomaly detection.

The associative analysis helps in bringing out some of the hidden relationships among the data items in the broad set of data. This can even help in predicting the occurrence of a particular item in an event or transaction whenever some other things are present. You can also think of this as a conditional probability.

Regression is used to predict up with a dependent variable by constructing a model or a mathematical function out of indecent variables.

Summarization helps in coming up with a short description of the entire data sets. Data mining is integration and combination of various techniques, which include machine learning, statistics, pattern recognition, etc. while there is even a right amount of intersection between data mining and machine learning data, as both go together and algorithms of machine learning are also used for mining data.

 1. R
