I propose a new algorithm for multi-armed bandits that is fully deterministic, as fast and simple to implement as UCB1, and yet, for a very broad range of practical circumstances empirically outperforms many of the existing industry standard Bernoulli multi-armed bandit policies, including Thompson Sampling and UCB1 and UCB-tuned. tl;dr: Get a summary of this … Continue reading "Improving on the UCB1 multi-armed bandit algorithm"

This post applies the weighted Hodges–Lehmann estimator to mixture distributions, studying how well it tracks the dominant component. In Pragmastat, Center is the recommended robust location estimator. Confidence intervals are available via CenterBounds . pragmastat.dev github.com/AndreyAkinshin/pragmastat The classic non-weighted [[hodges-lehmann-estimator|Hodges-Lehmann location estimator]] of a sample $\mathbf{x} = (x_1, x....

As someone with years of experience using and teaching Ansible I want to share with you how I teach it to my colleagues in the most practical way possible. However, before I get into the actual content of the training, it should be emphasized how important a functioning and identically set up working environment is for a successful learning journey. A prerequisite for participation in the training is the possession of a work device wi....

Paper link: https://arxiv.org/pdf/2008.13535 Learning to rank is an important problem in many machine-learning products such as search, recommendation, and advertising. Originally, many machine learning systems used simple logistic regression models, but it quickly became apparent that combining two or more features together was even better . This is called feature crossing. A lot of research and engineering work has gone into learni..

I propose an alternative to the Dead Internet Theory called the Living Dead Internet Theory, an exaggerated version of my actual beliefs: Any content written to optimize against algorithmic curation is as bad as algorithmically generated content. Algorithmically-curated content is disproportionally biased towards content optimized for said algorithm. The most accessible content might as well be written by bots. Don’t use short-tail se..

Or: Approaching the Y Combinator These are some of my class notes. Learning to derive the Y Combinator from first principles is something I’ve always wanted to do. This isn’t quite the Y Combinator, but it’s very close and it still gets you recursion without relying on recursive structures to begin with. In the beginning, we write a recursive function to compute the length of a list: ( let* ([ len ( λ ( lst ) ....

I was looking into compression of heightmaps for Substrata , and tried doing lossless compression in the following way: quantise terrain heights to 16 bit values, then try and predict the next value (using some previous values, see this tweet ) and then encode the difference between the prediction and the actual value (this is called the prediction residual). You end up with a bunch of residuals, that you then want to compress. I tried....

How software fails is interesting. But real-world errors can be infrequent to manifest. Fault injection is a formal-sounding term that just means: trying to explicitly trigger errors in the hopes of discovering bad logic, typically during automated tests. Jepsen and ChaosMonkey are two famous examples that help to trigger process and network failure. But what about disk and filesystem errors? A few avenues seem worth investigating....

Today I am thrilled to introduce the Shinobi Art Engine, the ultimate tool for creating NFT collections. This is an extension of the amazing work done by the HashLips team, known for their pioneering efforts in NFT art generation, and it’s the first tool to support both BCH and ETH NFT collections. The CashNinjas team has been working on this project for a while now and we are excited to share it with the world.
