Classifications

Astronomers have classified planetary systems into four distinct categories, based on the sizes and arrangements of their planets. As it turns out, the architecture of our own solar system is the rarest kind.Decades of telescopes dedicated to the hunt for worlds around stars other than our own Sun have yielded more than 5,300 of these exoplanets so far, contained in 3,910 planetary systems. With that much data astronomers have been able to classify these planets into different groups based on their characteristics – there…

Probabilistic Deep LearningThis article belongs to the series “Probabilistic Deep Learning”. This weekly series covers probabilistic approaches to deep learning. The main goal is to extend deep learning models to quantify uncertainty, i.e., know what they do not know.In this article, we present an examination of the Naive Bayes algorithm for classification tasks using a dataset of wine samples. The Naive Bayes algorithm is a probabilistic machine learning technique based on Bayes’ theorem, which makes assumptions about…

Distill Fine-Grained Features Without SupervisionFigure 1. Self-supervised learning is an important step to true artifical intelligence. Image retrieved from Unsplash.Previously, I have written several articles briefly discussing self-supervised learning and, in particular, contrastive learning. What was not yet covered, however, was a concurrent branch of self-supervised approach using interactions of multiple networks that seems to emerge and excel recently. As of today, one of the state-of-the-art training methods is a…

Google has reenabled the validate fix feature in Google Search Console while launching the new “more simplified” classifications for the coverage reports. This was expected, earlier this month Google temporarily disabled the validate fix feature in order to launch these new classification labels. Validate fix is back. Now when you go into Google Search Console and click on some of the coverage reports, the “validate fix” button should be back. Google disabled it while upgrading…

Google changed how it is displaying errors within some of the Search Console reports to show only valid or invalid classifications, the company announced today. Instead of the coverage report showing errors, valid with warnings and valid; now the report just shows invalid or valid information. What changed. Google said the URLs or items in the Search Console report are no longer grouped at the top level by three or more status categories, i.e. Valid, Warning, and Error. Now they…

Take your analysis of binary classification problems to the next level using the binclass-tools amazing Python packageImage by the authorData Scientists who are about to train classification models often find themselves analyzing the resulting confusion matrix to see if the model’s performance is satisfactory. Let’s take a closer look at what this is all about.Introducing the Confusion MatrixThe term “confusion” refers to the fact that an observation can be correctly or incorrectly predicted by the model, which then can…
