Deep Learning in R – MNIST Classifier with Keras In a day and age where everyone seems to know how to solve at least basic deep learning tasks with Python, one question arises: How does R fit into the whole deep learning picture? You don’t need deep learning algorithms to solve basic image classification tasks. Here’s how to classify handwritten digits with R and Random Forests. Here is some good news for R fans – both Tensorflow and Keras libraries are available to you, and they’re easy to configure. Today you’ll learn how to solve a well-known ... Read More

Feed: SAS Blogs. Author: Robert Allison. This is another in my series of blog posts where I take a deep dive into converting customized R graphs into SAS graphs. Today we'll be working on bubble maps - specifically, plotting earthquake data as bubbles on a map. R bubble map, created using geom_polygon() and geom_point() SAS bubble map, created using Proc SGmap My Approach I will be showing the R code (in blue) first, and then the equivalent SAS code (in red) that I used to create both of the maps. Note that there are many different ways to accomplish the same things in ... Read More

Feed: R-bloggers. Author: Rstats on Jakub Nowosad's website. TLTR: Quantifing changes of spatial patterns requires two datasets for the same variable in the same area. Both datasets are divided into many sub-areas, and spatial signatures are derived for each sub-area for each dataset. Next, distances for each pair of areas are calculated. Sub-areas with the largest distances represent the largest change. To reproduce the calculations in the following post, you need to download all of relevant datasets using the code below: library(osfr) dir.create("data") osf_retrieve_node("xykzv") %>% osf_ls_files(n_max = Inf) %>% osf_download(path = "data", conflicts = "overwrite") You should also attach the ...

Part 2: What image format should you use for graphics. Part 3: Including external graphics in your document (this post). Part 4: Optimal {knitr} settings. In this third post, we’ll look at including eternal images, such as figures and logos in HTML documents. This is relevant for all R markdown files, including fancy things like {bookdown}, {distill} and {pkgdown}. The main difference with the images discussed in this post, is that ... Read More

Feed: CIO. Author: . The H-1B visa program is probably the most well-known US federal employment visas, and arguably the most controversial. Businesses say it’s too restrictive. Labor organizations complain that it displaces US workers and lowers their wages. Some politicians use it to appeal to their base with scant ability to fix the process to the benefit of all.

Be aware that the rules and internal business processes of the H-1B visa are complex. Either could be ... Read More
