Amazon is rolling out new features that make it easier for customers to search for specific items in large databases of images and videos. The tech giant said Monday it will make "Custom Labels" available next month, allowing Rekognition users without any machine learning experience to deploy the software more nimbly. Custom Labels allow customers to train Rekognition to detect specific objects and scenes related to their use case. For example, a retailer who wants to identify all of the black boots in her online inventory could train the software with images of shoes that meet that description, so that it can detect them in a larger library of images. That type of custom sorting previously required machine learning expertise to build a model from scratch, an Amazon spokesperson said.
