Rago v1 1B

Rago v1 1B is a 1B parameter retrieval-augmented generation-optimized model built by Neural Bridge AI and trained on RAG Full Dataset 20000. It is available under Apache license 2.0.

Model Description

Rago v1 1B model is a retrieval-augmented generation-optimized (RAGO) model, which enhances large language models by integrating an external authoritative knowledge base (context) for generating responses. This integration significantly improves the model's ability to produce relevant, accurate, and context-specific output across specialized domains or internal data without necessitating retraining. It addresses key challenges of large language models (LLMs), such as unpredictability, reliance on potentially outdated data, and the propagation of incorrect information, thereby improving user trust in AI applications. Rago v1 1B, specifically, is an advancement built upon the Falcon-RW-1B model, optimized for retrieval-augmented generation, making it particularly effective in contextually aware response generation.

Training Data

Rago v1 1B has been trained using the Neural Bridge's RAG Full 20000 dataset, which comprises a blend of RefinedWeb, gms8k, and RAG Hallucination Dataset 1000.

Training Details

In terms of training specifics, Rago v1 1B is built upon Falcon-RW-1B employing LoRA to enhance the model's capability to deliver relevant, precise, and context-specific output across specialized domains or internal datasets. This approach aims to tackle significant challenges faced by LLMs, such as unpredictability, reliance on potentially outdated information, and the spread of incorrect data. The architecture of Rago v1 1B mirrors that of Falcon-RW-1B, augmented with LoRA adapters. The model is trained with 4-bit quantization on a single NVIDIA A100 GPU for approximately one hour, utilizing a learning rate of 2e-5 with cosine scheduler, alongside the following LoRA parameters:

• LoRA Rank (R): 32
• LoRA Alpha: 64
• LoRA Dropout: 0.05
• Target Modules: query_key_value, dense, dense_h_to_4h, dense_4h_to_h

Rago v1 1B benefits from a custom data collator designed to boost model performance significantly. Employing a masked language modeling (MLM) strategy, the model is fine-tuned to generate more accurate responses by exclusively masking the answer portion of the training data. This custom data collator has led to noticeable improvements in the model's factuality performance.
