One of the major challenges that users face when trying to do data science in Mathematica with the Wolfram Language is how to handle big data. Leaving aside the important topic of database connectivity/functionality and the handling of data too...
I would like to create a challenge for Community users as described below. I would welcome comments and suggestions from the Community as to how to improve the description of the challenge, or its structure. The aim of the challenge will be to...
Does anyone know of any (worthwhile) examples of iOS apps created for Wolfram Player? I've played around with it a little, enough to discover that, with the exception of textbook apps, most CDF-apps are virtually unusable, at least on my iPhone. ...
It's rather fun to experiment with Mathematica's ImageRestyle function, which can produce some interesting results when applied iteratively. In this illustration we start with a photographic image of Zurich: img = ![enter image description...
I am using Mathematica V12.3 on an Aurora-Ryzen with GeForce RTX 2090 and v11.3 of the NVIDIA toolkit. All the latest paclets/drivers are installed. There are multiple reports of Mathematica not working properly with NVIDIA CUDA (cf...
I have written extensively about statistical arbitrage strategies in other posts, for example: - [Succesful Statistical Arbitrage][1] - [Developing Statistical Arbitrage Strategies Using Cointegration][2] - [Pairs Trading with Copulas][3] ...
Over on Stack Exchange a [user][1] posted the following [question][2]: > This is a basic question about using the KalmanFilter function. I > want to use the KalmanFilter function (or other related Kalman Filter > functions in Mathematica) to...
Is it just me, or are community posts not being updated? I recently received email notification that some posts I follow had been updated, but I don't see the updates. For example, I don't see this post (or various others I have been notified of,...
This is a snippet from a strategy backtesting system that I am currently building in Mathematica. One of the challenges when building systems in WL is to avoid looping wherever possible. This can usually be accomplished with some thought, and the...
