The algorithm was trained using hand-drawn images from children as well as drawings from trained psychologists. Duckweed is a plant that negatively impacts Lake Titicaca. Duckweed Vacuum Cleaner classifies and removes the plant from the water. This prototype uses a camera to collect data for its image recognition algorithm. Even though dentists report that proper tooth brushing can help in maintain oral health, an increasing number of children are facing tooth decay problems.
