During AI image inpainting, a user uploads an image with a cat, intending to add a hat to it using a text prompt. The AI, however, replaces the cat's tail with a second hat instead of adding one on the cat's head. Which limitation of current AI models does this outcome MOST clearly demonstrate?

Difficulty differentiating object attributes (e.g., a hat on the head versus a hat as a tail). (C) Signup and view all the answers

Consider a scenario where a generative AI model is trained to produce photorealistic images of birds. After extensive training, the model consistently generates images of birds with an additional, subtly distorted, but discernible artifact resembling a watermark in the lower-right corner. This artifact is never present in the training data. What is the MOST probable cause of this phenomenon?

Latent space entanglement, where the model has inadvertently mapped a specific region of its latent space to encode the 'watermark' because of subtle biases in the training setup. (D) Signup and view all the answers
