Making Sense of AI Hallucinations: Our Holistic Guide to Illuminating AI Pathways

As large language models (LLMs) with generative AI applications become increasingly sophisticated, there is a growing concern about the potential for these models to produce inaccurate or misleading output.  This issue is known as “hallucination,” where AI models produce completely fabricated information that’s not accurate or true.  Hallucinations can have serious implications for a wide range of applications, including customer service, financial services, legal decision-making, and medical diagnosis.
Hallucination can occur when the AI model generates output that is not supported by any known facts. This can happen due to errors or inadequacies in the training data or biases in the model itself and large language models rarely say they do not know an answer. To mitigate this risk, researchers are exploring several approaches. One is to introduce more constraints on the model’s output, such as limiting the length of responses or requiring the model to stay within the realm of known facts. Another approach is to incorporate feedback from humans, as is done in RLHF allowing them to flag and correct any errors or false information. Transparency in AI models is also an important factor, especially when it comes to decision-making processes. By making these processes more transparent, it becomes easier to identify and correct errors or biases that may lead to hallucination.

While these solutions are promising, they are by no means foolproof. As AI models become more complex and capable, it’s likely that new issues will emerge that require further research and development. By remaining vigilant and proactive in addressing these challenges, we can ensure the benefits of generative AI are realized while minimizing potential risks. 

As the field of AI continues to evolve, it will be essential for researchers, developers, and policymakers to work together to address emerging issues and ensure that these technologies are used in a responsible and beneficial way. In doing so, we can unlock the full potential of AI while eliminating the potential for harm. 

Understanding AI Hallucination

AI hallucination happens when smart models give us information that is not true or completely made up. This can be a problem in important areas like health care, finance, legal decisions, and customer service. It can really change people's lives.

There are many things that can cause these hallucinations. They include bad or not enough training data, AI models that are too fit to their training data, not understanding the context, not having enough knowledge in a certain area, and attacks from bad people. So, we need to find ways to deal with these problems to make sure the AI of tomorrow is smart and can be trusted.

The solution to hallucinations

To solve the problem of AI hallucination, we need a mix of many solutions that work together.

First, we need to set clear limits for how the AI model should work, making sure it sticks to what is true and doesn't make things up. It's like having signs in a maze to guide you.

Second, we need to get feedback from people. This is done in Reinforcement Learning with Human Feedback (RLHF). It's like having a guide in the maze who points out mistakes and wrong information, helping the AI be more accurate.

Lastly, we need to be clear about how AI models make decisions. This is like having a light in the maze. By doing this, we can find and fix any mistakes or biases that may cause hallucinations, making sure the AI is a good guide.

Hallucinations Tackling, Powered by Indika

Preventing hallucination in GPT AI models will require a multifaceted approach that incorporates a range of solutions and strategies. By continuing to explore new methods and technologies, researchers can help ensure that these powerful tools are used in a responsible and beneficial way.

At Indika AI, we understand the importance of addressing the issue of hallucination in generative AI models. As a strategic AI partner offering data services, we have developed innovative solutions to help minimize the risk of hallucination and improve the accuracy and reliability of generative AI models.

Diverse High-quality Training Data to Prevent Hallucinations in AI Models

One of the key ways that Indika is addressing the issue of hallucination is by providing diverse and high-quality training data for AI models. By using a diverse range of training data, we can help ensure that AI models are exposed to a wide range of contexts and scenarios, which can help prevent the model from generating inaccurate or misleading output.

In addition to providing high-quality training data, Indika is also developing innovative solutions to help improve the context of decision-making processes in AI models. One of these solutions involves using natural language processing (NLP) techniques to analyze the context of a given input and provide additional information to the model.

For example, if a customer service chatbot receives a question from a user, we can improve the model efficiency by using different NLP technique such as Name Entity Recognition or Sentiment analysis. These allow us to analyze the context of the question and provide additional information about the user’s history, preferences, and past interactions with the chatbot. The additional information can help the model generate more accurate and relevant responses, while also minimizing the risk of hallucination.

The Importance of Human in the Loop in Tackling Hallucinations

Another innovative solution that Indika offers to tackle hallucination in generative AI models is the use of reinforcement learning with human feedback (RLHF). RLHF involves developing a reward model based on human preferences and feedback that will be used to steer the language model toward more alignment, ie helpful, honest and harmless output.

Imagine a healthcare organization that wants to develop an LLM to help diagnose and treat patients. They might use Indika’s human-in-the-loop system to train and validate their model. Human experts, such as doctors and nurses, would review the model’s output and provide feedback on whether it is accurate and relevant to the patient’s symptoms and medical history. This feedback would then be used to steer the model behavior toward more alignment and improve its accuracy, which may include for the model to learn to say that it cannot answer a question with certainty. Additionally, Indika’s team of linguists and language experts could provide context and domain knowledge to the model, helping it to better understand medical terminology and generate more relevant outputs.

In addition to providing oversight, humans can also be used to provide feedback and corrective input to the model. This involves monitoring the output of the model and flagging any responses that are inaccurate or inappropriate, as well as providing corrective feedback to help the model learn and improve over time.

By using human-in-the-loop for hallucinations tackling in the example above, the healthcare organization can develop a more accurate and reliable LLM that can assist medical professionals in diagnosing and treating patients. The model can also be continuously updated and refined based on new data and feedback, ensuring that it remains accurate and up-to-date. This can ultimately lead to improved patient outcomes and more efficient use of healthcare resources.

Explainability and Interpretability

Finally, Indika is also developing innovative solutions to improve the explainability and interpretability of AI models, which can help prevent hallucination and ensure that the output of the model is transparent and understandable.

For example, in a legal decision-making application, an AI model could be used to generate potential legal arguments or decisions based on historical case data. However, to ensure that the output of the model is transparent and understandable, the decision-making process of the model can be explained using natural language and visualizations, which can help human experts understand and evaluate the model’s output.

At Indika AI, we are committed to developing innovative solutions to help tackle the issue of hallucination in generative AI models. By providing high-quality training data, improving the context of decision-making processes, using reinforcement learning with human feedback, and improving the explainability and interpretability of AI models, we can ensure these powerful tools are used in a responsible and ethical way.
