The inter-galactic visitor is a cold, active cryovolcanic comet zipping through the skies and has earned a wicked nickname – the ‘Devil Comet’ – since it periodically explodes violently.A periodical comet, named ’12P/Pons-Brooks’ is scheduled to greet Earth from its closest point in the dark skies from April 21 as it zooms towards the sun on its return journey after 71 years, exciting the international scientific community.This week, the comet gave its early glimpses to humanity as a bright, tiny spot which was captured…

Forget about artificial intelligence (AI) and all that fancy math for a moment. Let’s talk about cheese. Specifically when you are creating a charcuterie board. If you’re not familiar, the United State’s version of a charcuterie board is (literally) a board of wood or stone with a spread of meats, cheeses, and other tasty bits. If you’re doing it right, each meat on the board has been meticulously paired with a specific cheese to complement flavor, texture, and appearance (we eat with our eyes, you know). Creating a board…

The class neighborhood of a dataset can be learned using soft nearest neighbor lossIn this article, we discuss how to implement the soft nearest neighbor loss which we also talked about here.Representation learning is the task of learning the most salient features in a given dataset by a deep neural network. It is usually an implicit task done in a supervised learning paradigm, and it is a crucial factor in the success of deep learning (Krizhevsky et al., 2012; He et al., 2016; Simonyan et al., 2014). In other words,…

Astronomers have detected a supermassive black hole ripping a passing star to shreds. Not only was this cataclysm closer to Earth than ever seen before, but its location and light emissions were unusual, hinting at a large unseen population of these events.Black holes are notorious for gobbling up anything that gets too close, and that includes stars. But it’s not a neat little slurp – black holes are far messier eaters than you might expect, stretching objects out and throwing matter all over the place. When stars are on…

This artist’s impression depicts a white dwarf star found in the closest known orbit around a black hole. NASA’s Chandra X-ray Observatory discovered this extraordinarily close binary in 47 Tucanae, a dense cluster of stars on the edge of the Milky Way.

Visual Understanding of the Models and the Impacts of HyperparametersK Nearest Neighbors or KNN is one of the most simple models in machine learning. In fact, to some extent, there is no model, because, for the prediction of a new observation, it will use the entirety of the training dataset to find the “nearest neighbors” according to a distance (usually the euclidean distance). And then in the case of a regression task, the prediction value is calculated by averaging the target variable values of these neighbors.Since…
