Army researchers have developed a pioneering framework that provides a baseline for the development of collaborative multi-agent systems.

The framework is detailed in the survey paper “Survey of recent multi-agent reinforcement learning algorithms utilizing centralized training,” which is featured in the SPIE Digital Library. Researchers said the work will support research in reinforcement learning approaches for developing collaborative multi-agent systems such as teams of robots that could work side-by-side with future soldiers.

“We propose that the underlying information sharing mechanism plays a critical role in centralized learning for multi-agent systems, but there is limited study of this phenomena within the research community,” said Army researcher and computer scientist Dr. Piyush K. Sharma of the U.S. Army Combat Capabilities Development Command, known as DEVCOM, Army Research Laboratory. “We conducted this survey of the state-of-the-art in reinforcement learning algorithms and their information sharing paradigms as a basis for asking fundamental questions on centralized learning for multi-agent systems that would improve their ability to work together.”

Misfits Market is an online grocery delivery service that sells “ugly” organic produce for cheap. In the first four months of 2021 alone, Misfits Market rescued the same amount of food it saved in 2020 as a whole. In 2020, Misfits Market shipped 77 million pounds of food to more than 400000 households across the U.S. Since launching in 2018, Misfits Market has expanded to both coasts, has over 1000 employees and has received over $300 million in funding. Bloomberg reports its valuation tops $1 billion, putting it into unicorn territory. But Misfits Market wasn’t an obvious success. In fact, it was just one of many businesses started by its 29-year-old founder Abhi Ramesh.

The study found that children following vegan diets were on average 3 cm (1.2 inches) shorter, had 4–6% lower bone mineral content and were more than three times more likely to be deficient in vitamin B-12 than the omnivores.

Children on vegan diets have a healthier cardiovascular profile and less body fat than their omnivore peers, but the diets may affect growth, bone mineral content and micronutrient status, according to researchers from UCL Great Ormond Street Institute of Child Health and the Children’s Memorial Health Institute in Warsaw, Poland.

The peer-reviewed study, published in the American Journal of Clinical Nutrition, also found that children following vegetarian diets had a lower risk of nutritional deficiencies compared to the omnivores, but a less healthy cardiovascular profile.

Many people are looking for ways to reduce their consumption of animal products. And these days, there are a ton of plant-based alternatives to help them do that. But many companies are working on ways to make animal-free animal products like meats, milk, and even egg whites. So, it may soon become possible to eat less meat without actually eating less meat!
