Hallucination Phenomena

Sometimes, a machine learning model makes predictions or generates data that isn't grounded in its training data. Imagine teaching a computer to recognize cats by showing it pictures. If it starts to say that it sees cats in images without cats, that's a hallucination. The computer is seeing things that aren't there. This can happen when the model is too complex or hasn't been appropriately trained, leading to incorrect or nonsensical outputs.

What is Hallucination in AI?

Hallucination in artificial intelligence (AI), also known as confabulation or delusion, refers to a confident response by an AI system that is not justified by its training data. In a loose analogy with the human psychological phenomenon of hallucination, AI hallucination is related to unjustified responses or beliefs. This became prominent with the rollout of large language models (LLMs) like ChatGPT, where users noticed the bots often generated plausible-sounding but incorrect information.

Why is Hallucination in AI important?

AI hallucination raises critical questions about the trustworthiness and reliability of AI systems. It can lead to the spread of misinformation and can have severe implications in fields like law, finance, and journalism, where accuracy and reliability are paramount. Understanding and mitigating hallucination in AI is a crucial task for developers, users, and regulators of AI technology.

Hallucination in generative AI is concerning because it can create unrealistic or incorrect data. In applications like image generation, this might lead to objects that don't actually exist. In more critical areas, like medical imaging or self-driving cars, hallucinations could result in harmful or dangerous mistakes. Therefore, understanding and controlling this phenomenon is crucial for creating reliable and safe generative AI models.

Examples of AI Hallucinations

AI hallucinations can lead to misinformation and even recommend malicious software packages. Therefore, it's important for organizations and users to double-check the accuracy of LLMs and generative AI output. Here are some examples of AI hallucinations:

1. Google's chatbot Bard incorrectly claimed that the James Webb Space Telescope took the first image of a planet outside the solar system.

2. Bing provided an incorrect summary of facts and figures in an earnings statement from Gap.

It's clear that trust in chatbots to generate truthful responses all the time is not advisable.

What Causes AI Hallucinations?

Some of the critical factors behind AI hallucinations are:

  • Outdated or low-quality training data
  • Incorrectly classified or labeled data
  • Factual errors, inconsistencies, or biases in the training data
  • Insufficient programming to interpret information correctly
  • Lack of context provided by the user
  • Struggle to infer the intent of colloquialisms, slang expressions, or sarcasm

Writing prompts in plain English with as much detail as possible is essential. As such, it is ultimately the vendor’s responsibility to implement sufficient programming and guardrails to mitigate the potential for hallucinations.
