Have you noticed any Artificial Intelligence hallucination? The concept may seem confusing and generate doubt, but you have most likely already interacted with a chatbot or even with a generative AI engine and got an answer completely outside of what was asked/requested. Or worse, he wholeheartedly believed in false information created by AI. Yes, Artificial Intelligence hallucinates, and often produces situations that pose challenges for users and developers. Learn more about hallucinations and how to avoid them below.
Hallucinations
First of all, it is necessary to emphasize that there is no scientific consensus on the use of the term “hallucinations” to describe such a phenomenon. Some scholars and experts say not being able to credit something too human, like a hallucination, to a machine that has no consciousnessThe statement makes sense, but the term has become popular among the community as a whole because it clearly exemplifies this “confusion” of AI.
Conceptually, Hallucinations are incorrect or misleading results generated by AI. These errors can be caused by a variety of factors, including insufficient training data, incorrect assumptions made by the model, and/or biases in the data used to train the model..
Some developers, however, try to play the blame for hallucinations on the users' lap; according to them, imprecise, generic, and confusing questions and/or instructions generate inadequate results. In theory, AI is only as good as the pilot operating it. It makes sense, but the point is that hallucinations appear even when the input data is structured and accurate.
And that's where the danger lies. Think, for example, of AIs trained to make important decisions, such as medical diagnoses or financial negotiations – the impact of errors generated by AI in these contexts is gigantic.
How do Hallucinations occur?
You AI engines are trained on data and learn to make predictions by finding patterns in the data. It turns out that the accuracy of these predictions depends on the quality and integrity of training data.
This is precisely the number one factor that reduces the quality and accuracy of AI responses. If the training data is biased, flawed, or incomplete, the AI model will only learn incorrect patterns., generating inaccurate predictions and hallucinations.
That's why it's so important that when developing a chatbot and/or integrating a generative AI engine into an internal or external flow, companies must perform extensive data mining and curation, so that they can feed the Artificial Intelligence engines with qualityThis is precisely the biggest challenge facing companies today.
However, it's not just faulty training data that leads to hallucinations. Lack of adequate foundation is another factor to consider.. You AI models may have difficulty accurately understanding real-world knowledge, physical and natural properties, and factual informationAnd when this foundation is missing, the model generates outputs that it considers plausible, even though they may be incorrect, untrue, or even meaningless.
It's not uncommon to discover that AI has invented something that doesn't exist, fabricated dates, and/or created events. This is quite dangerous.
Examples of AI Hallucinations
Hallucinations can take many forms. But in general, involve 3 contexts:
Incorrect predictions: the AI model can predict that an event will occur based on its training data, even if it is completely unlikely.
False positives: The AI model may mistakenly identify something as a threat. Consider, for example, a fraud detection model that flags a legitimate transaction as fraudulent.
False negatives: the AI model fails to identify/select something it should, missing it; a serious risk, for example, in medical diagnostics.
How to avoid hallucinations?
The question that won't go away: Is there a cure for these hallucinations?
In short: yes! But there is no “silver bullet” or something that will completely eliminate any possibility of AI error. Some ways to control hallucinations:
Limit the possible outcomes
When training AI engines it is important to limit the number of possible outcomes that the model can predict. Something like “by limits” in generating results. This can be done through a technique known as Regularization. Regularization penalizes the AI model for making overly extreme predictions, which helps generate responses, preventing Artificial Intelligence from “going off on a tangent”.
Train AI only with relevant and specific sources
It's quite a lot tempting to feed AI with all the data on the internet, empowering it to respond and interact in a near-omniscient manner. In fact, this can work for some businesses.
However, the variety and abundance of data can (and should) generate inaccuracies in the results.
For AI models that require extremely high precision and/or whose incorrect results can have crucial impacts on people's lives, it is advisable to use only data relevant to the task the model will performFor example, if AI is used for specific medical diagnoses, use only medical data and images.
Create a model for the AI to follow
When training an Artificial Intelligence engine it is highly advisable to create standards for the model to follow. By “standards”, understand unify information and present it in an orderly manner (with topics, numbers, connections). Learning is faster and the risk of inappropriate associations is lower.
Tell AI what you don't want
When training the AI model it is also preponderant to tell her what you don't want her to generate. “Set limits” on this technology. For example, a company's generative AI chatbot should under no circumstances direct the user to the competitor.
Guardrails, or protective grids (in literal translation), It is precisely the system and/or practice of including mechanisms so that the AI engine does not generate discriminatory, unethical or illegal results.. And more: that he ensure data privacy and confidentiality both the company and the users.
Hallucination-Free AI?
Will we have an AI without hallucinations? Get correct and reliable 100% responses to the input data?
As said, everything depends on the integrity of the training data, the limitations of the results and the limits imposed on this generationExperts on the subject agree that we created a monster (generative AI) and now we are trying to tame it – a Herculean task, but one that has been producing satisfactory results in certain businesses and segments.
