High-quality internal support is significant for employee experience and retention.
AI systems built on natural language generation, or NLG, have seen a limited ability to enable a better internal support experience for employees with NLP-related task requirements.
With the advent of the GPT-4 approach, employees can surface information efficiently and effectively.
However, GPT-4 models train on massive data to a certain cutoff point.
There are many instances of natural language generation by GPT-4 models that produce answers for users with the highest probability of hallucinations and misinformation on top of generic answers.
Businesses can produce relevant and accurate responses only through authoritative sources rather than models trained with public data.
The RAG, or Retrieval Augmented Generation approach, becomes highly efficient and effective in overcoming the challenges of generic answers, including hallucinations.
But what is RAG? How can it help with employee support, which GPT-4 or ChatGPT-like interfaces lack when it comes to delivering relevant and accurate responses across business-specific scenarios?
In this article, we’ll learn about RAG or Retrieval Augmented Generation and its outstanding capability to augment LLM searches and responses to enhance employee support.
RAG, or Retrieval Augmented Generation, is an AI framework or a search retrieval process that optimizes large language model-generated responses by referencing authoritative data from external sources and providing augmented contexts for LLM answers to ensure relevancy and accuracy.
Simply put, RAG augments the context of LLM searches by leveraging custom data from external data sources.
Large language models, generative AI, or GPT-4 models generally train on cutoff public data points.
This means that language models can easily access diverse datasets of specific thresholds.
However, this can pose challenges for internal users with their support assistance. There are three major challenges withLLM-related searches or information:
LLM or NLG searches information based on predefined patterns guided by algorithms. Although this ability allows LLMs to produce human-like responses, they largely lack context when asked to deliver responses to specific questions. LLMs have limitations in adapting to diverse sets of data and retrieving contexts, resulting in the delivery of generic responses like that of Google Search Engine results.
It is quite common for LLMs to train on a cutoff data point. For example, ChatGPT contains data up to 2021. LLMs can only answer questions related to that specific period. Language models hardly give answers for the current period. This tendency leads them to make up whimsical conclusions about concepts and hallucinate. Answers can be highly wrong and lack factual context.
LLMs' semantic or neural capability can only understand what is inside their pre-trained data. It cannot adapt to what is not explicitly stated as required in the constant real-time nature of back-and-forth conversations.
Although it can answer relevant questions, but lacks the emotional intelligence to adapt to dynamic conversation settings.
Imagine your employee asking the neural or semantic search system inside your LLM a question about holiday leave policies. The system can search for relevant information from the embedded knowledge and provide the answers.
But if he asks, ‘I want to head to a new destination. How can I plan my leaves?’ This indicates leave requests. Without understanding dynamic concepts of conversations, an LLM can give irrelevant or no answers.
Here’s RAG helps.
The idea of RAG is to augment the existing LLM capability of generating answers by adding contexts while improving the conversational experience for semantic or neural search results and output delivery.
By blending pre-trained LLM model capabilities and neural or semantic search, the retrieval model or RAG ensures the veracity of responses and keeps up with dynamic conversational requirements.
A retrieval approach for large language systems can efficiently help fetch relevant answers from whatever sources it is linked to while building contexts for LLM to improve validity, accuracy, and relevance for domain-specific use cases.
Given LLM’s tendency to hallucinate, produce misinformation, or give irrelevant answers, wC3.ai CEO Tom Siebel opines that Generative AI would transform companies, and the RAG approach helps solve AI risks.
Normally, a generative AI system searches information for user queries from datasets it is trained on or what it already knows.
Using a retrieval system for LLM solutions, RAG utilizes user input to find relevant information from its external data sources. It presents new findings and user inputs to LLMs, which use new knowledge and training data to generate a better and more contextual response.
Any data outside of LLM training data is referred to as external data. These datasets can comprise anything, such as APIs, repositories, databases, etc, in any format that can be synced using a connector.
To help RAG improve the relevancy of user inputs, LLMs need vector databases or embeddings to convert queries into numerical representations. Using embedding methods, the Retrieval Augmented Generation approach retrieves relevant documents similar to user queries and returns exact results through numerical representations that an LLM can understand.
The retrieval systems augment user inputs (prompts) and use them to retrieve relevant text data for context, a process known as prompt engineering. These augmented prompts can help LLMs provide correct answers.
The augmented prompts with enhanced context can be accessed through LLM endpoints for queries asked. LLM endpoints can be synced with chatbot applications or other systems.
Large language models or Generative AI systems are efficient in natural language generation. LLMs can summarize, translate, generate new content, and capture insights using prompts. These capabilities facilitate greater user interactions in customer or employee support by integrating retrieval systems.
Here are the RAG efficacies for LLMs:
A retrieval system tied with LLM for chatbots helps users derive accurate answers automatically from external databases. It can also automate routine tasks such as follow-up conversations and resolve issues in real-time.
A retrieval system can easily adjust to a diverse data ecosystem, making it extremely easy to prevent the generalization of information and effectively help surface information for users they want to perform a task.
You can add company data, such as HR policies, marketing information, sales details, etc., to provide more context for your users' queries. Instead of raising general answers, users can ask specific questions about their work and processes.
While RAG systems can enhance search and knowledge capabilities, users can maximize the RAG approach to improve workplace interaction, efficiency, and productivity.
Depending on the use cases RAGs can unlock, these applications can help augment employee support in various ways.
Just as retrieval models are used for question-and-answer chatbots, employee queries can find extended levels of efficiency for search results. Your employees can use retrieval systems within an LLM-powered chatbot to find answers to their queries.
Apart from static answers, an RAG approach helps improve conversational requirements, accuracy, empathy, and the relevancy of information searches.
You can easily assist various support use cases, such as ‘reset passwords,’ ‘unlock accounts,’ ‘onboard new hires,’ ‘offboard,’ ‘add users,’ etc in a dynamic way.
A retrieval system that augments prompts for user inputs and adds contexts can improve employees’ interest in adopting self-service. Users are more inclined to get help from self-service rather than ask for help from human agents.
RAG systems augment information relevancy by matching relevant data in the training data while also referring to past user interactions to build context for LLMs and ensure response accuracy.
As a result, users handle queries related to mundane processes by themselves and improve productivity.
A Retrieval-Augmented Generation approach increases self-service capabilities, ultimately reducing ticket volumes for tier 0 and tier 1. As a result, agents can have enough time to address critical tickets and achieve success.
Retrieval Augmented Generation solutions can unlock many benefits for businesses and your service desk support users.
