But using these models without customization is still not enough. Language models for business can be customized to the requirements in 2 ways- Fine tuning LLMs or Crafting Custom Training Documents.  

Language Models For Business: Understanding Fine Tuning LLMs

Fine-tuning language models for business refers to the process of customizing a pre-trained model to perform specific tasks or adapt to a particular domain or dataset. Language models are typically pre-trained on vast amounts of text data to learn the general structure, syntax, and semantics of language. However, these pre-trained models may not be optimized for specific tasks or domains out-of-the-box. Fine-tuning involves further training the pre-trained model on a smaller, task-specific dataset or domain-specific data to improve its performance on a particular task. During fine-tuning, the model’s parameters are adjusted or updated based on the new training data, allowing it to learn task-specific patterns and details.

The process of fine-tuning typically involves the following steps:

1. Preparation of Training Data: Collecting or creating a dataset that is relevant to the task or domain you want the model to perform well on. This dataset is labeled or annotated with the correct outputs for the task (e.g., sentiment labels for sentiment analysis).
2. Loading the Pre-trained Model: Initializing the pre-trained language model and loading its parameters.
3. Adding Task-Specific Layers: Adding additional layers on top of the pre-trained model to adapt it to the specific task. For example, adding a classification layer for text classification tasks or a decoder for sequence-to-sequence tasks.
4. Fine-tuning on Task-Specific Data: Training the combined model (pre-trained model + task-specific layers) on the task-specific dataset. During training, the parameters of the pre-trained model are updated based on the task-specific data, while the parameters of the added layers may also be updated.
5. Evaluation: Evaluating the fine-tuned model on a separate validation or test dataset to assess its performance on the task.

Language Models For Business: Understanding Training Custom Documents

Crafting custom training documents for language models for business involves the creation of a dataset tailored to a specific task, domain, or application. Unlike pre-trained language models, which are trained on large corpora of general data, custom training documents are designed to train a language model on a specific set of inputs and outputs relevant to a particular use case. This process enables the language model to learn task-specific patterns, terminology, and details, thereby improving its performance on the targeted task. Documents having brand guidelines, product information are created specifically for this.

The steps involved in crafting custom training documents for language models typically include:

1. Create Foundational Model: Begin by selecting a suitable foundational language model architecture. This serves as the basis for further customization and training.
2. Fine-tune Model: Fine-tuning the foundational model involves training it on a specific dataset or task to improve its performance in that domain. This process typically involves adjusting the model’s parameters and updating its weights based on the task-specific data.
3. Reinforcement Learning with Human Feedback: Incorporating reinforcement learning with human feedback allows the model to learn from user interactions and improve over time. Human feedback helps refine the model’s responses and adapt to user preferences and requirements.
4. Upload Bulk Files: Upload bulk files containing the training data relevant to the target task or domain.
5. Upload Single File: Alternatively, upload a single file or document containing curated data for training the model. This approach may be suitable for smaller-scale projects or when working with a specific dataset.
6. Document Processing: Process the uploaded documents to extract relevant information, clean the data, and prepare it for training. This involves tasks such as text normalization, tokenization, and data preprocessing.
7. Tokenization: Tokenize the text data to break it down into smaller units (tokens) such as words or subwords. This step helps the model process and understand the textual input more effectively.
8. Word Embedding Aggregation: Convert the tokenized text into word embeddings or vector representations. Word embedding aggregation techniques such as averaging or pooling may be used to combine multiple word embeddings into a single representation for the entire document.
9. Semantic Space Text Embedding: Embed the processed text data into a semantic space where similar documents or concepts are represented closer together. This facilitates semantic search and retrieval of relevant information.
10. Vector Data Storage: Store the processed text data and embeddings in a vectorized format suitable for training the language model. Vector data storage allows for efficient retrieval and manipulation of the training data during the training process.
11. Semantic Search: Implement semantic search capabilities to enable users to search for documents or information based on semantic similarity rather than exact keyword matches. Semantic search enhances the model’s ability to retrieve relevant results and understand user queries more accurately.

GRYD- A GenAI Pipeline That Works For Your Enterprise

Large language models for business offer remarkable capabilities in understanding and generating human-like text, but they are not without limitations. The popular language models available in the market today only know what is there in their training data. So when a company wants it to answer questions about its own business, these LLMs might not have the right answers. this creates a challenge making it tricky for businesses to get trustworthy outputs tailored to their needs.

Two significant limitations in pre-existing language models for business include:

1. Hallucination: LLMs can confidently produce incorrect or misleading information, a phenomenon often referred to as hallucination. This occurs when the model generates responses that are not grounded in reality or are based on incorrect assumptions. Hallucination can arise due to various reasons, including biases in the training data, lack of context awareness, or the model’s inability to verify the accuracy of the information it generates. As a result, relying solely on LLMs for information retrieval or decision-making can lead to inaccurate outputs.
2. Data Coverage: Another limitation of LLMs is their reliance on pre-existing data for training. If the model has not been trained on the specific information or domain you require, it may lack the knowledge or understanding to provide accurate responses. This limitation can manifest as gaps in the model’s knowledge or its inability to comprehend specialized terminology or contexts. In such cases, the model may produce generic or nonsensical responses, highlighting the importance of domain-specific training.

These limitations can be overcome with the use of GRYD. GRYD comes with Generative search; Generative search is a powerful technique that retrieves relevant data to provide context to LLMs along with a task prompt. It is also called as RAG.

Generative search overcomes the limitations in 2 steps:

1. Retrieve the relevant information through the query.

2. LLM is prompted with the combination of retrieved data
