Can We Tell if Machine-Learning AI Models Are Working Correctly? | Sci-Tech Daily

To see if the assessment approach is ineffective, MIT researchers designed a mechanism for modifying the original data so they may be sure which properties are crucial to the model. The next test is whether feature-attribution algorithms can appropriately identify those essential characteristics using this changed dataset. They discovered that even the most popular approaches frequently overlook significant elements in images and that some methods barely outperform a random baseline. This might have far-reaching consequences, particularly if neural networks are used in high-stakes scenarios such as medical diagnosis. The researchers plan to apply this review process in the future to look into other subtle or realistic aspects that might contribute to false associations.

Robots rise to meet the challenge of caring for old people | Nature.com

The demand for automated assistance is increasing as the world’s population ages. According to World Health Organization projections, there are more than 1 billion persons over the age of 60, with that number expected to rise to 1.4 billion by 2030 – that’s one out of every six people, necessitating the hiring of additional 6 million nurses. McGinn and his colleagues constructed Stevie, a white robot on a rolling platform with short, adjustable arms and a head with cartoon eyes and a mouth, to figure out how robotics may be utilized in elderly homes. Many of the robot’s skills are already present in other devices, but they are frequently underutilized, according to McGinn. The robot is designed to make technology easier to use.

Space Force Submitting ‘Bold’ Budget Request for 2023 | National Defense Magazine

The Space Force’s 2018 budget proposal will be “bold,” according to the service’s senior general, and will further the Pentagon’s pursuit of a better satellite infrastructure that is more impervious to enemy strikes or other interruptions. The unveiling of President Joe Biden’s fiscal year 2023 budget proposal is keenly anticipated by defense experts. Annual presidential budget presentations to Congress are usually made in February, but according to sources, the next one might be postponed until March. Meanwhile, Congress has failed to pass a full-year funding bill for the fiscal year 2022, and federal agencies are functioning under a continuing resolution that will run until February 18. The Space Force has proposed $17.4 billion in spending for 2022, up 13.1 percent from 2021.
