Exploring the beauty of mapping between spaces in SVMs, autoencoders, and manifold learning (isomaps) algorithmsPhoto by Evgeni Tcherkasski on UnsplashIntroductionIn machine learning, understanding how algorithms process, interpret, and classify data relies heavily on the concept of “spaces.” In this context, a space is a mathematical construct where data points are positioned based on their features. Each dimension in the space represents a specific attribute or feature of the data, allowing algorithms to navigate a…

UKCEH hedgerow map shown overlaid on the landscape of south Lincolnshire. Credit: Google Earth Scientists have harnessed cutting-edge technology to produce the most comprehensive map of hedgerows across the length and breadth of England. The researchers at the UK Centre for Ecology & Hydrology (UKCEH) hope this innovative mapping will guide planting and restoration of these vulnerable habitats to support wildlife and…

(a) Map of study areas on the Seward Peninsula, Alaska (location shown in map inset) shown on the Bing Imagery basemap. The blue point shows the location of the city of Nome, AK. The three study locations (Teller 27, Teller 47, and Kougarok) are indicated by the white circles. Hillshade maps are of the three study sites (b) Teller 27, (c) Kougarok, (d) Teller 47. The points indicate the location of the ground truth observation of permafrost presence…

A few years ago, a couple of Google employees reached out to a Minnesota scientist with an unusual proposal: What if they could teach computers to spot beaver habitats from space? "They wanted to know if I thought it was possible to find beaver wetlands from aerial imagery myself, and then if that could be scaled up with machine learning," Emily Fairfax, a University of Minnesota beaver researcher and assistant professor of geography, told As It Happens guest host Megan Williams.Fairfax knew that beavers' sprawling dams…

Halfway between Tasmania and…

Researchers have created the first comprehensive cell atlas of a mammalian brain, mapping over 32 million cells in the mouse brain. This atlas, part of the NIH BRAIN Initiative, offers unprecedented insights into brain cell types and connections, advancing our understanding of the human brain and aiding in developing new treatments for brain disorders. Credit: SciTechDaily.com A groundbreaking cell atlas mapping the entire mouse brain, detailing over 32 million cells, paves the way for a deeper understanding of the human…

Researchers have mapped over 2.3 million brain cells from mice, shedding light on how different brain cell types are formed through gene regulation. This work, part of a larger effort to create a detailed brain cell atlas, has significant implications for understanding brain function and treating neuropsychiatric disorders. UC San Diego researchers are translating the language of brain cells, and it’s helping them figure out what goes wrong in diseases of the brain. Despite all our cells sharing the same DNA, there are…

Researchers at the University of York have mapped the evolutionary history of crocodiles, revealing the impact of climate change, competition, and ecological factors on their current limited diversity, providing vital insights for conservation efforts. Credit: Jagged Fang designs Researchers have mapped the family tree of crocodiles and their extinct relatives to shed new light on why there are so few species of the giant reptiles living today. The research team, led by scientists at the University of York, mapped the…
