Feed: Featured Blog Posts - Data Science Central. Author: Damian Widera. I have been frequently asked about the tools for the Machine Learnign projects There are lot of them on the market so in my newest post you will find my view on them. I would like to start my first Machine Learning project. But I do not have tools. What should I do? What are the tools I could use? I will give you some hints and advices based on the toolbox I use. Of course there are more great tools but you should pick the ones you like ... Read More

Feed: Featured Blog Posts - Data Science Central. Author: steve miller. I enjoy data prep munging for analyses with computational platforms such as R, Python-Pandas, Julia, Apache Spark, and even relational databases. The wrangling cycle provides the opportunity to get a feel for and preliminarily explore data that are to be later analyzed/modeled. A critical task I prefer handling in computation over database is data loading. This is because databases generally demand the table be created before records are inserted, while computational platforms can create/load data structures simultaneously, inferring attribute data types on the fly (these datatypes can also be ...

Feed: R-bloggers. Author: ntguardian. This article is also available in PDF form. A while back someone posted on Reddit about the grading policies of their academic department. Specifically, the department chair made a statement claiming that grades should be Normally distributed with a C average. I responded, claiming that no statistician would ever take the idea that grades follow a Normal distribution seriously. Some asked for context, and I wrote a long response explaining my position. I repeat that argument here, and also give some R code demonstrations showing what curving grades does. A cheap shot would be to say ... Read More

Feed: R-bloggers. Author: John Mount. A point that differs from our experience struck us in the recent note: A development environment specifically tailored to the data science sector on the level of RStudio, for example, does not (yet) exist. “What’s the Best Statistical Software? A Comparison of R, Python, SAS, SPSS and STATA” Amit Ghosh Actually, Python has a large number of very capable integrated development environments, some of which are specifically tailored for data science. Please read on for a small list of tools, and my recommendations for a specific data science in Python toolchain. Off the top of ... Read More

Feed: Planet MySQL; Author: Severalnines; Despite the fact that PHP 5 has reached end-of-life, there are still legacy applications built on top of it that need to run in production or test environments. If you are installing PHP packages via operating system repository, there is still a chance you will end up with PHP 5 packages, e.g. CentOS 7 operating system. Having said that, there is always a way to make your legacy applications run with the newer database versions, and thus take advantage of new features. In this blog post, we’ll walk you through how we can run PHP 5 ... Read More

Feed: R-bloggers. Author: ntguardian. This article is also available in PDF form. I started my first research project as a graduate student when I was only in the MSTAT program at the University of Utah, at the very end of 2015 (or very beginning of 2016; not sure exactly when) with my current advisor, Lajos Horváth. While I am disappointed it took this long, I am glad to say that the project is finished and I am finally published. Our article, entitled “A new class of change point test statstics of Rényi type”, is available online, published by the Journal ... Read More

Feed: Featured Blog Posts - Data Science Central. Author: steve miller. After posting my most recent blog using census data to illustrate handling "large" dataframes in R exploiting fst and feather file formats, I realized I could have taken the analysis a step further. Recall my then description of "demographic information on both American households and individuals (population). The final household and population data stores are quite large for desktop computing: household consists of almost 7.5M records with 233 attributes, while population is just under 15.8M cases and 286 variables." In addition to working with the two individual dataframes/data.tables, one could also consider the ... Read More

Feed: Featured Blog Posts - Data Science Central. Author: Divya Singh. A Hearty Welcome to You!I am so thrilled to welcome you to the absolutely awesome world of data science. It is an interesting subject, sometimes difficult, sometimes a struggle but always hugely rewarding at the end of your work. While data science is not as tough as, say, quantum mechanics, it is not high-school algebra either. It requires knowledge of Statistics, some Mathematics (Linear Algebra, Multivariable Calculus, Vector Algebra, and of course Discrete Mathematics), Operations Research (Linear and Non-Linear Optimization and some more topics including Markov Processes), Python, R, ...

Feed: Featured Blog Posts - Data Science Central. Author: steve miller. I recently downloaded a 5 year Public Use Microsample (PUMS) from the latest release of the American Community Survey (ACS) census data. The data contain a wealth of demographic information on both American households and individuals (population). The final household and population data stores are quite large for desktop computing: household consists of almost 7.5M records with 233 attributes, while population is just under 15.8M cases and 286 variables. In addition to enabling a wealth of demographic analyses, these census data are quite suitable for performance testing functions to ingest, munge, ... Read More
