Data mining Data mining is the computational process of discovering patterns in large data sets involving methods at the intersection of artificial intelligence, machine learning, statistics, and database systems.[1] It is an interdisciplinary subfield of computer science.[1][2][3] The overall goal of the data mining process is to extract information from a data set and transform it into an understandable structure for further use.[1] Aside from the raw analysis step, it involves database and data management aspects, data pre-processing, model and inference considerations, interestingness metrics, complexity considerations, post-processing of discovered structures, visualization, and online updating.[1] Data mining is the analysis step of the "knowledge discovery in databases" process, or KDD.[4] Etymology[edit] In the 1960s, statisticians 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 5 Best Free Tools For Making Slick Infographics It's not enough to simply write about data any longer; the world wants visuals. While there are many professional information designers making a name for themselves, such as Nicholas Felton of, the majority of these digital artists are up to their eyeballs in high-paying work. Where does this leave you? Well, if you want to spruce up your documents, blog posts, and presentations, there are some free tools online that can help. Many Eyes This IBM Research tool gives you two choices: an option to browse through existing sets of data, or use your own.

12 – Les mathématiques de la beauté… This post investigates female attractiveness, but without the usual photo analysis stuff. Instead, we look past a woman's picture, into the reaction she creates in the reptile mind of the human male. Among the remarkable things we'll show: Backdoor (computing) A backdoor in a computer system (or cryptosystem or algorithm) is a method of bypassing normal authentication, securing unauthorized remote access to a computer, obtaining access to plaintext, and so on, while attempting to remain undetected. The backdoor may take the form of an installed program (e.g., Back Orifice) or may subvert the system through a rootkit[1] Default passwords can function as backdoors if they are not changed by the user. Some debugging features can also act as backdoors if they are not removed in the release version.[2] A backdoor in a login system might take the form of a hard coded user and password combination which gives access to the system. Many computer worms, such as Sobig and Mydoom, install a backdoor on the affected computer (generally a PC on broadband running Microsoft Windows and Microsoft Outlook).

Blog Accurate predictions remain the Holy Grail of every business intelligence initiative. Reporting data to show what definitely happened is beneficial. Analyzing data to determine why things happened the way they did is even better. Data Mining - PPDM Wiki From PPDM Wiki Introduction Traditional data analysis is done by inserting data into standards or customized models. In either case, it is assumed that the relationships among various system variables are well known and can be expressed mathematically.

Platform as a service Platform as a service (PaaS) is a category of cloud computing services that provides a computing platform and a solution stack as a service.[1] Along with software as a service (SaaS) and infrastructure as a service (IaaS), it is a service model of cloud computing. In this model, the consumer creates the software using tools and/or libraries from the provider. The consumer also controls software deployment and configuration settings. The provider provides the networks, servers, storage, and other services that are required to host the consumer's application.[2] PaaS offerings facilitate the deployment of applications without the cost and complexity of buying and managing the underlying hardware and software and provisioning hosting capabilities.[3] There are various types of PaaS vendors; however, all offer application hosting and a deployment environment, along with various integrated services.

Understandable Big Data: A survey Survey LE2I UMR6306, CNRS, ENSAM, Univ. Bourgogne Franche-Comté, F-21000 Dijon, France Data Mining Image: Detail of sliced visualization of thirty video samples of Downfall remixes. See actual visualization below. As part of my post doctoral research for The Department of Information Science and Media Studies at the University of Bergen, Norway, I am using cultural analytics techniques to analyze YouTube video remixes. My research is done in collaboration with the Software Studies Lab at the University of California, San Diego. A big thank you to CRCA at Calit2 for providing a space for daily work during my stays in San Diego.
