How Do Companies Use Data Mining?

data mining


Data mining is a process of data science technology. The data science technology works completely on the data so do the data mining. In this technology, many processes are involved, but data mining is said to be the most important one. In the data mining process, the collected data is analyzed for discovering the hidden patterns in it. The data is collected before analysis. The data which is collected is in impure form. This means that all the data which is accumulated is not of use. We have to use only useful information from it. That’s why data mining is done.

The data mining process discovers the hidden patterns from the data which is further used for solving the problems. The data is divided into sub-parts and then data mining is performed on them. After the process, the data is integrated again. All these tasks are executed and accomplished at the place called data warehouses. The data mining process is majorly used by companies. This is so because this process helps in reducing the overall cost with higher revenue.


Here the steps followed in the data mining process are described precisely. They are listed below:

  • The data is first collected from the people with the help of different methods. 
  • After the collection of the data, it is transformed. 
  • After the transformation, the data is loaded into the data warehouses. 
  • When the data reach data warehouses, then it is managed and stored in the multidimensional databases. 
  • When the data is stored in the databases, the authorization is provided to the data scientists or data analysts for accessing the data. This is done with the help of application software. 
  • The data is then finally represented into easier and readable forms. For example, graphs, charts, etc.


At present, the companies are implementing the data mining process for making their business more efficient. Of course, the data mining process also provides high revenues at a low cost. This is another reason for using data mining in companies.

The first step of the companies is to gather the required data. Generally, the data of the company is classified into three types which are:

  • Metadata
  • Transactional
  • Non-operational 

The transactional data covers that data on which operations are performed on each day. For example, costs, inventory, sales, etc. Non-operational data includes the data of forecasting etc. While the metadata consists of the logical designs of the databases.


The most important thing for a company is the customers. For the success of a company, the company must have a strong base of customers. It is very important to keep your customers attracted to your company. Many companies fail to do so because they don’t know about what products their customers are looking for? Many companies are very slow. They are slow in understanding the needs of their customers. When a company slowly understands the needs of the customers, then they start to deploy the products of poor quality which are not appreciated and liked by the customers.

The data mining process helps in understanding the need of every customer by discovering hidden patterns from the data and by deep analysis of the data. One strong example of this is when looking at adult dating and hookup applications. Free sex apps like Meetnfuck App utilized data from users on other top casual sex sites in order to tailor their platform to better fit the needs of their target demographic. The examples of data mining to better understand customers are endless. Another example of this would be food delivery applications. We get many offers on food items every day. What these food delivery companies do is analyze the shopping behavior of every customer. They analyze that which food item is frequently purchased by which customers. Then they make the clusters of those customers who purchase the same food items. Then they provide special offers to the customers accordingly. In this way, the data mining process help in building a strong customer base.


The companies invest a huge amount of money in the marketing and advertisement campaigns of their products. Even after this, many of them fail in promoting their products. This is so because the marketing and advertisements are not reached to the right audience. As said above, the data mining process help in understanding the needs of the customers. After knowing the needs of the customers, companies can easily deliver the products. The data mining process helps in keeping an eye on the online activities of the customers. For example, for what products they are searching for, which products or types of products are liked by the customers, etc.

The data mining process helps in doing the advertising and marketing to the targeted audience. This activity results in a lower cost with an efficient result. The best example of this would be Netflix. If you have the subscription of Netflix then you would better know that this application suggests next movies or series watch after finishing one. Netflix does so by analyzing the past data of its customers. It analyzes the past data as well as the last movies or series you have watched. Based on that analysis, it gives new suggestions. This activity also helps in building good relations with customers. That’s why data mining is being used by many companies around the world.


The companies have one more reason to use data mining in their business which is risk management. The data mining process prevents the company from many risks. The data mining process for risk management is more useful for financial institutions. The companies have to face many fake people who do not return the borrowed money. This activity leads the company to debt. With the help of data mining, the companies analyze the past data of their customers. The analysis of the internal data is preferred by the companies first. After the analysis, they decide whether it is safe to approve the loan to the applicant or not. Along with this, the data mining process also increases the quality of the tools which are used in risk management.

Understanding Some Commonly Used Machine Learning Algorithms

In the next ten years, it is believed that machine learning algorithms will replace many jobs worldwide. The growth of data is upgrading rapidly. Self-modifying and automated information is evolving and progressing, which results in extensive automation of data. 
The simplest example of the machine learning algorithm is the way computers play chess. The algorithm is designed to understand the player’s moves and play according to them. Before we get to the conclusion, let us know the basic idea of the machine learning algorithm.

What is a machine learning algorithm?  

A machine learning algorithm, in simple terms, is defined as an approach that works and runs on data. A user can build a production-ready model with the help of machine learning. 

In simple terms, if an airplane is using machine learning to accomplish a task, then the machine learning algorithm will be the engines inside of the plane which completes the job. Of course the use of machine learning has become vast, from our cars and favorite search engines to dating apps to meet milfs in your area.

There are three types of machine learning algorithms:

  • Supervised: In this learning, the algorithms are given a set of samples for prediction. The algorithms use patterns within the label to predict the outputs. Examples of supervised learning are Linear Regression, Decision tree, KNN.
  • Unsupervised: The data in this algorithm organize into a group of clusters. It then describes its structure. The learning algorithm then converts complex data into a simple and organized way for analysis. An example of unsupervised learning algorithms is K-means and Apriori algorithms. 
  • Reinforcement: with this algorithm, the machine is designed to make specific decisions. The device uses the trial and error met hid to train itself continuously. It learns from its past mistakes and captures knowledge to make correct decisions. An example of a reinforcement learning algorithm is the Markov decision process. 

Some of the commonly used machine learning algorithms is as follows:

  • Naïve Bayes Algorithm

The algorithm is based on the Bayes theorem. It assumes that in a class, the presence of a specific feature is not related to any of the other components. The theorem means that the elements are all independent of each other. 

The theorem is based on probabilities. It is one of the most popular algorithms as it is straightforward and easy to understand. The algorithm is efficient and valuable for large database sets.

  • Linear Regression

 The Linear regression algorithms show the relationship between two variables. It also shows that when one variable has an impact, the other variable is also affected. The algorithm helps to estimate the real continuous value of the products. 
Some of the common examples are sales predictions, employee salary estimation, and predicting housing prices. 

When the independent and dependent variables fit into a line, a relationship is established. The line is known as the regression line. It is presented by the equation Y= a*X+b. Y is the dependent variable, x is the independent variable, a is the slope, and b is the intercept. 

Linear regression is based on predictions and is made of two types; simple and multiple linear regressions. Single linear regression is made by one independent variable, and multiple is characterized by more than one variable. 

  • Decision tree

The Machine learning algorithm; decision tree is one of the most used and popular algorithms. It helps in classifying problems. It is one of the most reliable and popular learning algorithms for the classification of issues. 

Categorical and continuous dependent variables categorically work very well with the decision tree algorithm. The algorithm works by splitting homogeneous groups by taking remarkable attribute variables. 

The learning algorithm makes a graphical representation of a tree and its branches. 
A decision tree helps in capturing ideas if there is confusion on how to operate a situation. 

  • Logistic regression

The algorithm performs classification of tasks, unlike linear regression that performs regression problems. It works by applying a logistic function to a variety of features. The algorithm then predicts the outcome of an attribute variable. 

It is also called logit regression as it adds data to the logit function and predicts probability. The output value comes between 0 and 1. 

  • SVM(support vector machine) algorithm

The learning algorithm works in a classification method. Each data is the plot in an n-dimensional space, where n is the number of features. The value of each feature variable is attached to a particular coordinate. It helps to make it easy to analyze the data. The line splits the data, which are called classifiers, and it then plots the features into the graph for analysis. 

  • KNN algorithm 

The KNN (k-nearest neighbor) algorithms work well for regression and classification problems. It is one of the most simple machine learning algorithms.

The algorithm stores all the available cases. It then classifies new topics by voting, the majority vote, of its K- neighbors. The most common class to the instances is then assigned, and a distance function performs the measurements. 

A simple example to explain the algorithm is by comparing it with real life. If you want to buy vegetables, then you will have to look around in markets and shops. The shop with a variety of fresh vegetables and is nearest to your location is the one you will choose to purchase. 

What Are the Top Data Science Programming Languages?

A formal language which consists of instructions set that produce different types of output is called a programming language. These kinds of languages are used in the programs of the computer for implementing the algorithms and comprises of several apps. You can find different programming languages for data science. Many of the data scientist need to master and learn at least a single programming language. Because it is crucial device to realize the functions of data science. There are two kinds of programming languages one is high level and low level. The language of low level is less developed and computers most understandable language for performing various function.

SQL in other words a structured query language has turned into a prominent programming language for maintaining the information over the years. Even though it is not utilized for performing the operations of data science, SQL tables and queries can really help data scientists in dealing with the systems of data management. This is one of the domain specific language which is extremely comfortable for manipulating, retrieving, and storing the information in databases that are relational.


Scale is the elegant and modern programming language produced in the year of 2003. It was actually designed to identify the problems associated with Java language. Its range of application from the programming of web to machine learning. It is also one of the effective and scalable languages for big data handling. In todays companies, this programming language is supporting functional and object oriented and also synchronized and concurrent processing.


It is the most popular data science programming language in the recent days. Python is easy to utilize and an open source programming language which is in the field of programming languages from the year 1991. Python is a dynamic as well as object-oriented programming which supports various paradigms from functional to structured and programming of procedure. Such that it is considered as the prominent programming language for data scientists also. It consists of less than 1000 iteration so it is a best and fast choice for the manipulations of data. The processing of natural data and learning of data is easier with the python having packages in it. Also, it is easier for programmers for reading the information in a spreadsheet for making an output of CSV.

Thus, these are some of the best data science programming languages.

Understanding Everything About Big Data

The term which actually describes large amount of data both structured and unstructured that overwhelm the business on the basis of every day is big data.
