Feed: R-bloggers. Author: R on Gianluca Baio. I was trying to find an apt image to accompany this post, but googling “sleek and shiny” mostly brought up images of women with ridiculously, well, sleek and shiny hair (and magical products to achieve just that), which has nothing to do with what I want to talk about here (not that this has ever stopped me including pics that have nothing to do with the actual post, of course…). Anyway, Andrea has been doing lots of work and has suggested an upgrade to the BCEAweb webapp, mainly involving a move towards Shiny ... Read More

We consider three settings (ε,L) = {(0.16; 40); (0.16; 50); (0.15; 50)}” Ziyu Wang, Shakir Mohamed, and Nando De Freitas. 2013 In an experiment with my PhD student Changye Wu (who wrote all R codes used below), we looked back at a strange feature in an 2013 ICML paper by Wang, Mohamed, and De Freitas. Namely, a rather poor performance of an Hamiltonian Monte Carlo (leapfrog) algorithm on a two-dimensional strongly correlated Gaussian target, for very specific values of ... Read More

Feed: R-bloggers. Author: filip Schouwenaars. The problem pkgdown is an R package that can create a beautifully looking website for your own R package. Built and maintained by Hadley Wickham and his gang of prolific contributors, this package can parse the documentation files and vignettes for your package and builds a website from them with a single command: build_site(). This is what such a pkgdown-generated website looks like in action. The html files that pkgdown generated are stored in a docs folder. If your source code is hosted on GitHub, you just have to commit this folder to GitHub, navigate ... Read More

As the the data space has matured, data engineering has emerged as a separate and related role that works in concert with data scientists. Ian Buss, principal solutions architect at Cloudera, notes that data scientists focus on finding new insights from a data set, while data engineers are concerned with the production readiness of that data and all that comes with it: formats, scaling, resilience, security, and more. Ryan Blue, a senior ... Read More

Feed: Databasejournal.com - Feature Database Articles. Author: . Typical big data applications have a load phase, where a snapshot of data is extracted from operational systems, transformed and cleaned, and then loaded into your big data appliance. Analysts and data scientists can then execute business analytics (BI) queries against the data store in search of patterns and potential marketing opportunities and cost savings. One disadvantage of this architecture is that your appliance becomes more like a large data warehouse, in that it does not contain the most up-to-date data. IBM now provides an option to configure its Db2 version 11 ... Read More

Feed: R-bloggers. Author: nsaunders. In summary: The code that generated the report (which I’ve used heavily and written about before) is at Github too. A few changes required compared with previous reports, due to changes in the rtweet package, and a weird issue with kable tables breaking markdown headers. I love that the most popular media attachment is a screenshot of a Github repo.
