Artificial Intelligence (AI) hallucination may sound perplexing, but it's a phenomenon where AI models generate outputs different from what is expected. Some AI models intentionally produce unrelated outputs, often seen in top text-to-art generators like DALL-E 2, creating novel images that could be termed "hallucinations."
In large language processing models like ChatGPT, hallucination can result in incorrect facts or made-up statements. Similarly, in computer vision, AI might mix images due to its inability to differentiate between similar entities.

AI hallucination occurs due to adversarial examples, where input data tricks AI applications into misclassifying them. Inadequate or inaccurate training data and resources can also lead to AI hallucination in language models like ChatGPT.
Spotting AI hallucinations involves detecting grammatical errors, illogical content, or deviations from expected patterns in computer vision and self-driving cars.
AI hallucinations are not conscious or subconscious like in humans but stem from limitations in training data and AI's inability to possess common sense or contextual understanding.
