A few hundred meters from our office, there is a little lunch place. It is part of a small chain that specializes in assemble-yourself, ready-to-eat salads. When we moved into our new office a few years ago, this salad vendor quickly became a daily fixture. However, overtime, this changed. We ...

Euler Problem 33 takes us back to the world of fractions from our primary school days. Many kids hate and struggle learning about fractions but once you master... The post Euler Problem 33: Digit Cancelling Fractions and Ford Circles appeared first on The Lucid Manager.

The most recent riddle on the Riddler consists in finding the shorter sequence of digits (in 0,1,..,9) such that all 10⁴ numbers between 0 (or 0000) and 9,999 can be found as a group of consecutive four digits. This sequence is obviously longer than 10⁴+3, but how long? On my trip to Brittany last weekend, […]

Introduction In this note we will show how to speed up work in R by partitioning data and process-level parallelization. We will show the technique with three different R packages: rqdatatable, data.table, and dplyr. The methods shown will also work with base-R and other packages. For each of the ...

Last time I promised to cover the graph-guided fused LASSO (GFLASSO) in a subsequent post. In the meantime, I wrote a GFLASSO R tutorial for DataCamp that you can freely access here, so give it a try! The plan here is to experiment with convolutional neural networks (CNNs), a form ...
