Abstract

The emergence of many competitors and entrepreneurs created a lot of excitement as companies competed to find new buyers and retain old ones. As a result of its predecessor, , the need for excellent customer service became relevant regardless of the size of the company. Additionally, each company\'s ability to understand the needs of each of its customers provides better customer support in its targeted delivery of his customer service and the development of customized customer service plans. This understanding is possible through \'s structured customer service. Each segment has customers with the same market characteristics. Big data ideas and machine learning have made automated customer segmentation approaches more widely accepted than traditional market analysis, which often fails on large customer bases. In this paper, the k-means clustering algorithm is used for this purpose. The Sklearn library was developed for the k-means algorithm (described in the appendix) , and the program is trained on his two-factor dataset of 100 samples obtained from a retail store. Characteristics of average purchasers and monthly average customers.

Introduction

I. INTRODUCTION

Over the years, increased competition among companies and the availability of extensive historical data have led to the widespread use of data mining techniques to find important and strategic information  hidden in company information. became. Data  mining is the process of extracting logical information from data sets and presenting it in an understandable way to support decision making. Data Mining Techniques  distinguishes areas such as Statistics, Artificial Intelligence, Machine Learning, and Data Systems . Data mining applications include, but are not limited to, bioinformatics,  weather forecasting, fraud detection, financial analysis, and customer segmentation.  The key to this document is the identification of commercial enterprise customer segments  using  data mining techniques. Customer segmentation is a grouping of a business customer base  called customer segments, each customer segment containing customers  who share  the same market characteristics. These differences are based on factors that directly or  indirectly affect the market or business, such as: B. Product preferences or expectations,  location, behavior, etc. The importance of customer segmentation includes, but is not limited to, a company's ability  to customize market plans suitable for  each segment of customers.  Supporting business decisions in high-risk environments, such as customer credit relationships.  Identify the products associated with  individual components and how supply and demand are managed.  It becomes clear that the interdependencies and interactions between consumers, between products, or between  customers and products may be unknown to the business.  Ability to predict customer rejection, predict which customers are likely to have problems, and provide clues to finding solutions.

II. LITERATURE REVIEW MATERIALS AND METHODOLOGY

A. Customer Classification

Over the years, the  world of business has become more competitive as  such organizations must meet the needs and desires of their customers, acquire   new customers and  improve their businesses. Identifying and  meeting the needs and requirements of each customer within the company is a very difficult task.  This is because customers can differ based on their needs, desires, demographics,  size, preferences, characteristics, etc. As it stands, treating all customers equally at store  is a bad practice. The challenge employs the concept of customer segmentation  or market segmentation. In this concept, consumers are divided into subgroups or segments, with members of each subcategory sharing similar market behaviors or  characteristics. Customer segmentation is therefore the process of dividing the  market into native groups.

B. Big Data

Recently, big data research is gaining momentum. Definition of Big Data – A term  that describes  large amounts of formal and informal data that cannot be analyzed by traditional  methods and algorithms.

Businesses collect billions of  data about  their customers, suppliers, and operations, and millions of interconnected  sensors  are turned into real-world devices such as mobile phones, cars, sensors, and   manufacturing and communications data. sent to the world. Ability to improve forecasting, save money, increase  efficiency, and improve various areas such as traffic control, weather  forecasting, disaster prevention, finance, fraud prevention, commerce, national  security, education, and healthcare. Big data is primarily seen in three Vs: volume,  volatility, and velocity. Other 2V available - authenticity and price so  5V.

C. Data Repository

Data collection is the process of gathering and measuring information about targeted changes in an established system that allows relevant questions to be answered and results to be evaluated. Data collection is part of research in all  of his  study areas, including natural sciences, social sciences, humanities and economics. The purpose of  all data collection is to obtain high-quality evidence that facilitates the analysis that builds concrete and misleading answers to questions. Collected data from , the UCI machine learning repository

D. Clustering Data

Clustering is the process of grouping information in a data set based on approximately  similarities. There are several algorithms scalar library.that can be applied to records based  on the provided condition . However, there is no universal clustering algorithm, so choosing the right clustering method is important. In this article, we  implemented three clustering algorithms using the Python

E. K-mean

The K-means  algorithm is one of the most popular classification algorithms. This  clustering algorithm is based on Centro, where each data point is placed in one of  duplicates pre-sorted with the K algorithm. Clusters are created that  correspond to hidden patterns in the data, providing the  information needed to assist in making execution decisions. process. There are many ways to configure K-Means, but we will use the  elbow method.

F. Methodology

The data used in this document was collected from the UCI Machine Learning  repository. This is a set of geographic data containing all transactions made with unregistered and unregistered brokers in the UK between 1st January 2010 and 12th September 2011. The  company  mainly sells unique gifts  at one time. Many of the company's customers are owners of his  shop. The database has eight attributes. These features are:

"Invoice: Invoice number. By default, a six-digit total number  is assigned to each transaction individually. If this code begins with the letter 'c', it indicates that  is void."

“Stock Code Code: Product (Item). name. A 5-digit number assigned only to individual his  products. “

"Definition: Product name (item). By name."

 "Price: Price for each product (item). Number."

 "Unit Price: The price is for 1 unit. Price, product price per unit. " 

"Customer: Customer number. Name, her 5 digit number for each customer. " 

Country: Country name. Name, the name of the country in which each customer resides.  In this white paper, we took several steps  to get accurate results. It contains the most common stage k-means algorithm, Feature  with Centros initial stage, allocation stage and update stage.

G. Data Collection

This is the data preparation phase. This function typically refines all data elements at a  standard rate of  and is useful for improving the performance of clustering algorithms. Each data point  varies from order 2 to +2. Integration methods including min-max, decimal, and -z-point are the default z-signature strategies used to make things uneven before the  dataset algorithm applies the k-means algorithm.

H. Methods Of Customer Classification

There are various methods of partitioning, differing in severity, data requirements, and  purpose. Below are some of the most commonly used methods, but this is not  an incomplete list. There are articles describing artificial neural networks,  particle determination, and complex type ensembles, but they are not included due to limited exposure to .

I may cover some of these options in future articles, but for now these general  methods will suffice. Subsequent sections of this article provide basic descriptions of the methods and code examples of the methods used. Skip the code if you don't have   expertise. You should familiarize yourself with the  in each of the four subsections of this article.

I. K-Means Encounter

The K-Means Clustering Algorithm is a commonly used algorithm for understanding  forms and differences in databases. Marketing often uses it  to build  customer segments and understand the behavior of these unique segments. Let's create a   assembly model in the Python environment.

J. Centroid Initiation

Selected cents or initials  selected. Figure 1 represents the beginning of  graduate centers. Four selected centers shown at different sizes were selected using the  Forgi method.  Forgy's method randomly selects data points  using k (in this case k=4) as the centroid of the  clusters.

K. Technical Introduction

The code below was written in the Jupiter manual using Python 3.x and some Python  packages to manipulate, process, analyze and visualize information. Most of the following  code is from his GitHub package for the book  Hands-on Data Science  for Marketing. This book is available from Amazon or Oil Reilly.  The open source data costs used in the  code below are from Irwin's Machine  Learning Repository.

III. MODELING AND ANALYSIS

1. Importing Packages: First,we need to import the packages to perform analysis and the excel spreadsheet where our data is present.
2. Data cleaning: Data which we are having should be clean and should be in a organizing form to perform actions.The data we are using is at csv file ,csv means comma separated values file which contains the data on which we are performing our analysis.
3. Handling Missing Data: If our dataset has any missing data,may leads to problems so it should be handled.We have different ways like deleting that row, calculating the mean.
4. Importing Dataset: The dataset we are using is present in xlxs file so to use that data we need to import it by using read_csv() function.
5. Selecting No Of Groups: To perform cluster analysis we need to find out how many groups it should have to select no of groups we are using elbow method which works by calculating the sum of squared errors.

Conclusion

Because our dataset is unbalanced, in this paper we have chosen an inner clustering validation rather than an external clustering validation that relies on external data such as labels. You can use internal cluster validation to choose the best clustering algorithm for your data set. And vice versa, you can correctly group data in clusters. Customer segmentation, if done properly, can have a positive impact on your business. You can offer special discounts and gift certificates to people with orange clusters to keep them longer. He can also advertise his hot-selling products by offering discounts to attract them. green clusters, you can organize the feedback column to find out what you can change to attract them. Based on the information above, we found the Jumbo Bag Red Retrospect to be the most expensive team\'s best-selling item. You can use this available information to make recommendations to other potential customers in this section.
