A better understanding of how these phytoplankton harvest and interact with light could lead to improved solar cells, sensing devices and optical components.

These systems have to be trained, often needing to learn to recognize objects from video or image data. This data often contains superfluous content that reduces the accuracy of models. So researchers found a way to incorporate natural hand gestures into the teaching process. This way, users can more easily teach machines about objects, and the machines can also learn more effectively. Tue, 01 Nov 2022 11:17:18 EDT //www.koonmotors.com/releases/2022/11/221101111718.htm
