The weekly puzzle from Le Monde is quite similar to older Diophantine episodes (I find myself impossible to point out): Give the maximum integer that cannot be written as 105x+30y+14z. Same question for 105x+70y+42z+30w. These are indeed Diophantine equations and the existence of a solution ...

Embracing Python in this tutorial series has long been a matter of time. For the last five years I have been championing R mostly because of its wide applicability and quite frankly, my own convenience. However, there is little any programming language can do to singlehandedly solve a variety of ...

Introduction Often, the model we want to fit is not a perfect line between some $x$ and $y$. Instead, the parameters of the model are expected to vary over $x$. There are multiple ways to handle this situation, one of which is to fit a spline. The spli...

DeepAI is a research company that develops a wide variety of deep neural network (DNN) models using the bleeding edge of AI research. For example, they have built models for sentiment analysis of text, nudity detection, artistic style transfer, text s...

In previous posts I introduced collapse, a powerful (C/C++ based) new framework for data transformation and statistical computing in R - providing advanced grouped, weighted, time series, panel data and recursive computations in R at superior execution speeds, greater flexibility and programmability. collapse 1.4 released this week additionally introduces an ...
