Answer key: AI Applications with No-Code Tools

(a) Train an AI model by giving examples and clicking, without writing code – Google Teachable Machine is one example.
(a) Many example images of that class – Then you train and test.
(a) Add more varied examples of both classes – Retrain and test again.
(c) 90% – 0.9 × 100 = 90%.
(a) It learned from one background and lighting, so new surroundings confuse it – Training with varied places and people makes it work more widely.
(a) Ask their permission and avoid sharing personal details – Keep the data private and delete it when the project ends.
