Best Practice to Prevent AI Hallucinations

Ever found that your AI assistant is just making things up as it goes along? When working with artificial intelligence, especially generative AI models (genAI) like large language models (LLMs), ensuring factual accuracy can sometimes feel like trying to nail jelly to a wall.

One moment, your AI chatbot is providing helpful, accurate information, and the next, it's confidently stating something completely fabricated.

This frustrating phenomenon has a name: AI hallucinations. And if you're using AI for business purposes, these fabrications can damage your credibility, mislead customers, and potentially create serious problems for your organization.

But don't worry – there are proven techniques to keep your AI firmly rooted in reality.

In this guide, we'll explore what AI hallucinations are, why they happen, and most importantly, how to prevent them through effective grounding techniques that keep your AI accurate and trustworthy.

What Are AI Hallucinations?

So what exactly are we talking about when we say "AI hallucinations"?

AI hallucinations occur when large language models generate content that's fabricated, inaccurate, or inconsistent with established facts. Unlike human lying, these aren't intentional deceptions – they're a side effect of how generative models work.

Think of it this way: When an LLM like GPT-4, Gemini, or similar AI models generates text, it's essentially predicting the most likely next tokens (words or parts of words) based on patterns it learned during training, not from a true understanding of reality. It's like someone who's really good at mimicking the style of experts without necessarily having the expertise themselves.

These hallucinations can take various forms:

• Inventing non-existent sources or citations
• Creating plausible-sounding but false information
• Misrepresenting facts while maintaining confidence
• Mixing accurate and inaccurate information seamlessly

Let’s learn why AI hallucinations can happen.

Why AI Hallucinations Happen

When you give an AI assistant a prompt, its goal is to generate a response that seems plausible based on the instructions. If the AI lacks the proper context and background knowledge, it may start "hallucinating" - making up information to fill in the gaps. Some common causes of AI hallucinations include:

• No relevant training data - If the AI simply hasn't been exposed to data from your domain, the model response won’t be grounded because it lacks the proper knowledge. Any specifics it generates are likely to be made up.
• Ambiguous or vague prompts - If your prompts don't provide enough constraints and details, the AI has more room for interpretation. This increases the chances of fabricated information.
• Asking about fictional contexts - Prompts that refer to imaginary products, people, or scenarios are prone to hallucinations since there are no facts for the AI to pull from.
• Insufficient contextual priming - Even if you provide some background info, the AI may hallucinate if it lacks the full context to understand your specific needs.

While AI hallucinations can be entertaining in some contexts, they have no place in business workflows where accuracy and trust are crucial.

After all, would you trust financial advice from someone who's making up numbers on the spot?

What Can We Do About It: Grounding AI

So how do you keep your AI assistant firmly planted in reality? The answer lies in a concept called "grounding" – connecting your AI to reliable sources of truth.

What Is Grounding AI?

Grounding is the process of anchoring AI outputs to verifiable, external sources of truth. In practical terms, it means connecting your AI systems to real-world data and established facts rather than relying solely on the patterns learned during pre-training.

When an AI is properly grounded, it generates responses based on specific information rather than statistical probabilities alone, much like how you might reference a textbook or database when answering a technical question instead of just going with your gut.

There are several approaches to grounding LLMs, with Retrieval-Augmented Generation (RAG) being among the most popular. RAG works by retrieving relevant information from external knowledge sources in real-time and incorporating it into the generation process.

Many developers implement RAG using Python frameworks that connect their knowledge bases to large language models. This helps provide factual support for the AI's responses while maintaining the fluent, natural language capabilities of generative models.

Think of it as giving your AI a personal research assistant who checks the facts before letting it speak – wouldn't that be nice?

The Best Practice of Grounding AI

The key to preventing hallucinations is grounding your AI by providing relevant data sources, reference materials, and background context. This gives the AI the knowledge it needs to generate accurate, tailored responses instead of making things up.

Some best practices for grounding your AI include:

• Upload relevant documents to InfoBase - Product specs, brand guidelines, writing samples, and other materials give the AI background knowledge to draw from. This creates a knowledge base that acts like your AI's personal library of facts.

• Pass data as inputs to workflows - Customer profiles, keywords, and other specifics prime the AI with details for each use case. It's like briefing a team member before they tackle a project.

• Train AI assistants on company data - Exposure to real data improves the AI's domain knowledge over time. Think of this as an extended onboarding process for your digital teammate.

• Tag InfoBase items - Makes it easy to reference relevant materials by topic. Imagine trying to find information in a filing cabinet with no labels – tagging creates an organized system.

• Continuously feed the AI real data - Ongoing learning prevents knowledge gaps that lead to hallucinations. Just as professionals need to stay current in their field, your AI models need fresh, real-world data.

• Review outputs and provide feedback - Human guidance helps further improve the AI's knowledge. Think of it as coaching – even the most sophisticated generative AI needs occasional course correction.

The goal is to determine what information your AI needs to have on hand to generate accurate, high-quality responses tailored to each situation. With the proper grounding, the AI won't need to make things up - it can pull relevant facts and terminology directly from the provided data sources.

The Benefits of Grounding Your AI

Wondering if all this extra effort is worth it? Spoiler alert: it absolutely is. Taking the time to properly ground your AI system pays off through:

• More accurate, factual outputs - The AI sticks to the specifics found in your data rather than fabricating information. No more playing "spot the fabrication" with your AI-generated content!
• Higher relevance and customization - Details from provided data improve personalization for different users and use cases. It's like having a chatbot that actually remembers your preferences instead of starting from scratch each time.
• On-brand, compliant messaging - AI follows brand voice and guidelines based on supplied materials. When you fine-tuning AI, you can maintain your tone whether it's corporate-professional or quirky-casual.
• Faster workflow creation - Less need to manually fix hallucinated outputs down the line. Would you rather spend time creating or endlessly editing? Grounding techniques front-load the work so you don't have to juggle corrections while riding the unicycle of tight deadlines.
• Greater user trust - Reliable, factual responses increase confidence in the AI. People quickly lose faith in tools that provide incorrect information – just ask anyone who's followed bad GPS directions!
• Reduced oversight needed - With quality grounding, minimal corrections to outputs should be required. Your team can focus on strategy rather than fact-checking.

Grounding sets your AI up for success by giving it the knowledge resources it needs to provide useful insights tailored to each situation, all while avoiding distracting false information.

Technical Implementation of Grounding AI

For those interested in the technical side, here's how grounding typically works under the hood:

Grounding often involves creating embeddings – numerical representations of text – and storing them in a vector database. When a user query comes in, the system leverages natural language processing (NLP) to understand the intent, then finds semantically similar content from your own data sources and includes it when generating responses. This ensures AI outputs are contextually relevant and factually accurate.

Many modern AI solutions implement this through APIs that connect to your existing systems, automatically enriching the AI's responses with relevant metadata from your knowledge base. Some implementations even incorporate Google Search capabilities to supplement your internal data with up-to-date information from the web when appropriate.

The key components of a well-grounded AI system include:

• A well-structured knowledge base containing your organization's data
• An embedding model that converts text into vector representations
• A vector database for efficient semantic search
• A retrieval mechanism that finds relevant information based on the user query
• An AI model that can incorporate this retrieved information when generating responses

The million-dollar question is: What information does your AI need to have on hand to generate accurate, high-quality responses tailored to each situation? With the proper grounding, the AI won't need to make things up - it can pull relevant facts and terminology directly from the provided data sources.

Real-World Applications of Grounded AI

Where can you apply these grounding techniques for maximum impact? Here are some practical use cases:

• Customer support AI agents that can accurately answer product questions by referencing up-to-date documentation
• Content generation apps that maintain factual accuracy while creating marketing materials
• Internal knowledge assistants that help employees find specific information across company resources
• Decision-making support tools that provide accurate data for business strategy
• Multimodal AI applications that can understand and generate content across different formats while staying factually grounded

In each case, the key is connecting your generative models to reliable, specific information sources that provide the external knowledge needed for accurate responses.
