Stanford path-planning algorithm enables autonomous multi-drone aerial surveys of Antarctic penguin colonies

Stanford University researcher Mac Schwager entered the world of penguin counting through a chance meeting at his sister-in-law’s wedding in June 2016. There, he learned that Annie Schmidt, a biologist at Point Blue Conservation Science, was seeking a better way to image a large penguin colony in Antarctica. Schwager, who is an assistant professor of aeronautics and […]

Inspired by Sudoku, U of T researchers create novel protein-folding algorithm for drug discovery

Computational biologists at the University of Toronto’s Donnelly Centre for Cellular and Biomolecular Research have developed an artificial intelligence algorithm that has the potential to create novel protein molecules as finely tuned therapeutics. The team led by Philip M. Kim, a professor of molecular genetics in U of T’s Temerty Faculty of Medicine and of computer science […]

Twitter Algorithm for Image Previews is Racist as well as Sexist? Netizens Show Examples Pointing to The Flawed Bias in Photo Cropping; Know What it Means

If you are regularly using Twitter then you’d know that the application crops images to give you a preview. This is why many users often write in the captions, open full image for surprise or just see full image. Now it has come to light that the image preview algorithm is highly racist and sexist. […]

New algorithm signals a possible disease resurgence

Scientists at the University of Georgia have used machine learning to predict the reemergence of existing infectious diseases. The algorithm monitors public health data to detect statistical patterns associated with impending outbreaks. The study, by Tobias Brett and Pejman Rohani, was recently published in PLoS Biology. While the method cannot predict the onset of a new disease like […]

Scientists use reinforcement learning to train quantum algorithm

Scientists are investigating how to equip quantum computers with artificial intelligence and machine learning approaches. This visualization of search path is obtained through reinforcement learning (RL) on a test problem with two parameters. The RL method leveraging past experience in solving similar problems quickly moves towards the solution to the unseen but similar problem. (Image […]
