Data Mining Explained With 10 Interesting Stories

In this paper we study user behavior in online dating, in particular the differences between the implicit and explicit user preferences. The explicit preferences are stated by the user while the implicit preferences are inferred based on the user behavior on the website. We first show that the explicit preferences are not a good predictor of the success of user interactions. We then propose to learn the implicit preferences from both successful and unsuccessful interactions using a probabilistic machine learning method and show that the learned implicit preferences are a very good predictor of the success of user interactions. We also propose an approach that uses the explicit and implicit preferences to rank the candidates in our recommender system. The results show that the implicit ranking method is significantly more accurate than the explicit and that for a small number of recommendations it is comparable to the performance of the best method that is not based on user preferences.

Looking for a perfect match-Why not try big data analysis this time?

Couples are finding love online and online dating today has become a big business. Online dating sites combine “data” and “analytics” to help people find their perfect soul mate. The real hero behind the success stories of online love is the big data analytics technology and infrastructure that help people find their perfect life partner based on their stated preferences and behavioural matching. Big data dating is the secret of success behind long lasting romance in relationships of the 21 st century.

This article elaborates how online dating data is used by companies to help customers find the secret to long lasting romance through data analysis techniques.

Some of the social websites are dating websites which members join in order to Based on original data in , data in are processed like data extraction.

Knowledge Discovery is the most desirable end-product of computing. Finding new phenomena or enhancing our knowledge about them has a greater long-range value than optimizing production processes or inventories, and is second only to task that preserve our world and our environment. It is not surprising that it is also one of the most difficult computing challenges to do well.

The main objective of knowledge discovery in Data Mining lies in the finding of data patterns. The knowledge about the current customers can be used to predict profitable customers based on their personal information. This explorative report focuses on analysing different methods of data mining to predict profitable customers of a dating site.

The second key aspect is to match individual customers based on their personal information. The dataset contains static activity and dynamic activity. Static activity includes all personal, demographic and interest information entered by the customer at its registration. The emails sent, channels communicated and kisses sent describe the dynamic activity. Table 1 shows the customer details in the table.

Another data table holds the information for users without stamps.

Data mining techniques for Social Science Research

There are 54 million single people in the U. As a result, about 20 percent of current romantic relationships turn out to have started online. Today, Peng Xia at the University of Massachusetts Lowell and a few pals publish the results of their analysis of the behavior of , people on an online dating site.

He decided to reverse engineer the match algorithm for OkCupid, the world’s largest free dating website with 14 million monthly active users.

A very large OKCupid dataset with attributes and over 68, instances has been analyzed to form clusters as an unsupervised learning task. The rationale behind the clustering is that broadly speaking, population can be segmented into clusters based on their behavioural attributes which in this project are accessed using OkCupid questions and answers and we can find a representative profile which broadly matches that cluster. I will be working with OkCupid’s dataset and using Weka to train, cluster and visualize OkCupid’s dataset.

Inspiration from this Math geek [1]. To be able to understand how OkCupid works, the first step was to create an almost-fake account for myself. The reason i say fake is because I’m not actively looking to date online. The reason i say almost is, I still want to be taken as a legit user by the online dating community. So here is what my profile looks like [2] :.

Next, I go on to see how to find matches for myself. OkCupid gives me the option to find matches according to preferred age, orientation, and location of who I want to meet. I make these changes in my “I’m Looking For” settings and this immediately adjusts the matches I see around the site. I however sort by match percentage because that is the parameter I am interested in for this project.

Data Mining

Mathematician Chris McKinlay wasn’t having any luck finding love, so he used an algorithm to crack the dating website OkCupid. The website OkCupid says we use math to get you dates. But the algorithms weren’t quite adding up for Chris McKinlay, who was a Ph. OkCupid matches users based on their answers to survey questions, and there are thousands of them, like: Do you have any tattoos?

And: How long you want your next relationship to last?

Unlike most online dating sites that keep their data of users’ flirtations a secret, the finds amusing correlations after data mining its data profiles. and personal and business websites to create dating profiles without users’.

Finding and Matching Communities in Social Networks Using Data Mining Abstract: The rapid growth in the number of users using social networks and the information that a social network requires about their users make the traditional matching systems insufficiently adept at matching users within social networks. This paper introduces the use of clustering to form communities of users and, then, uses these communities to generate matches. Forming communities within a social network helps to reduce the number of users that the matching system needs to consider, and helps to overcome other problems from which social networks suffer, such as the absence of user activities’ information about a new user.

The proposed system has been evaluated on a dataset obtained from an online dating website.

Social media mining

Artificial Intelligence And Its Genre 99 days ago. There are many different types of analysis to retrieve information from big data. 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.

Instead, he realized, he should be dating like a mathematician. OkCupid OkCupid’s matching engine uses that data to calculate a couple’s compatibility. Sheila was a web designer from the A cluster of young artist types.

Data mining is a process of discovering patterns in large data sets involving methods at the intersection of machine learning , statistics , and database systems. The term “data mining” is a misnomer , because the goal is the extraction of patterns and knowledge from large amounts of data, not the extraction mining of data itself. The book Data mining: Practical machine learning tools and techniques with Java [8] which covers mostly machine learning material was originally to be named just Practical machine learning , and the term data mining was only added for marketing reasons.

The actual data mining task is the semi-automatic or automatic analysis of large quantities of data to extract previously unknown, interesting patterns such as groups of data records cluster analysis , unusual records anomaly detection , and dependencies association rule mining , sequential pattern mining.

This usually involves using database techniques such as spatial indices. These patterns can then be seen as a kind of summary of the input data, and may be used in further analysis or, for example, in machine learning and predictive analytics. For example, the data mining step might identify multiple groups in the data, which can then be used to obtain more accurate prediction results by a decision support system.

Neither the data collection, data preparation, nor result interpretation and reporting is part of the data mining step, but do belong to the overall KDD process as additional steps. The difference between data analysis and data mining is that data analysis is used to test models and hypotheses on the dataset, e.

The related terms data dredging , data fishing , and data snooping refer to the use of data mining methods to sample parts of a larger population data set that are or may be too small for reliable statistical inferences to be made about the validity of any patterns discovered. These methods can, however, be used in creating new hypotheses to test against the larger data populations.

In the s, statisticians and economists used terms like data fishing or data dredging to refer to what they considered the bad practice of analyzing data without an a-priori hypothesis. The term “data mining” was used in a similarly critical way by economist Michael Lovell in an article published in the Review of Economic Studies in The term data mining appeared around in the database community, generally with positive connotations.

Chris McKinlay was folded into a cramped fifth-floor cubicle in UCLA’s math sciences building, lit by a single bulb and the glow from his monitor. The subject: large-scale data processing and parallel numerical methods. While the computer chugged, he clicked open a second window to check his OkCupid inbox. McKinlay, a lanky year-old with tousled hair, was one of about 40 million Americans looking for romance through websites like Match.

He’d sent dozens of cutesy introductory messages to women touted as potential matches by OkCupid’s algorithms. Most were ignored; he’d gone on a total of six first dates.

Like So while pursuing a Ph. How do you feel about tattoos; what is more offensive: book burning, or flag burning; how often do you mediate? To name a few of the thought-provoking and life inquests. McKinlay was chiefly interested in how members answered these questions. Do they tend to answer uniformly? Do their answers percolate throughout the space, similar if they answered by flipping a coin?

Or, do they clump around commonly held belief systems, and if so, by how much? Rolling up his sleeves, McKinlay determined that OkCupid members in the LA area at the time clustered into seven different groups, or user segments. Suddenly, he was the number-one match for more than 30, women — receiving approximately 88 unsolicited messages a week.

By comparison, a straight male on OkCupid, the median number of unsolicited messages is zero. Going on an average of one date a day, McKinlay vowed to keep the project alive until either one of two things happened: OkCupid shut him down or he met someone worth ending the project for.

The advent of powerful computers and Big Data analytics means matches The biggest challenge that online dating websites face is to make sure While sites like eHarmony and OKCupid have found success mining data.

A computer vision dating system analyzes combinations of face features of the system’s user’s photographs and recommends potential dating partners. A user selects preferred and not-preferred faces from a sample of other user’s pictures. The system analyzes the features of the preferred and not-preferred faces comparing the combinations of features in both categories with the features of other users in the database to find the users that most match the collective features preferred by the user.

These pictures are presented to the user. As the users are presented pictures after their sample selection, they can continue to select and reject pictures allowing the system to learn and refine the combinations of features and better locate those that most conform to a user’s most preferred photo images. The Internet has evolved significantly over past decades. With the speedy development of the internet, applications have grown rapidly such as Search Engines, Blogs, Social networking websites, E-commerce websites etc.

In these applications, social networking websites have become more and more popular. These websites enable users to create a profile of their personal information, keep in touch with their friends and even meet new people with similar interests. Some of the social websites are dating websites which members join in order to find suitable persons to date.

However, it is very difficult to find people to whom the user is attracted by their appearance and who may be attracted to the user especially in the large mass of people on dating websites. The search effort done manually can be time consuming and impractical. In attempts to solve the problem, search methods have been created, one of which is disclosed in U.
