RAGPT: Fine-tuned GPT-2 for Context-Based Question Answering

Model Description

RAGPT is a fine-tuned version of GPT-2 small, specifically adapted for context-based question answering tasks. This model has been trained to generate relevant answers based on a given context and question, similar to a Retrieval-Augmented Generation (RAG) system.

Key Features

Based on the GPT-2 small architecture (124M parameters)
Fine-tuned on the "neural-bridge/rag-dataset-12000" dataset from Hugging Face
Capable of generating answers based on provided context and questions
Suitable for various question-answering applications

Training Data

The model was fine-tuned using the "neural-bridge/rag-dataset-12000" dataset, which contains:

Context passages
Questions related to the context
Corresponding answers

Fine-tuning Process

The fine-tuning process involved:

Loading the pre-trained GPT-2 small model
Preprocessing the dataset to combine context, question, and answer into a single text
Training the model to predict the next token given the context and question

Hyperparameters

Base model: GPT-2 small
Number of training epochs: 3
Batch size: 4
Learning rate: Default AdamW optimizer settings
Max sequence length: 512 tokens

Usage

To use the model:

python

from transformers import AutoTokenizer, AutoModelForCausalLM

model_name = "BueormLLC/RAGPT"
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForCausalLM.from_pretrained(model_name)

# Prepare input
context = "Your context here"
question = "Your question here"
input_text = f"Contexto: {context}\nPregunta: {question}\nRespuesta:"

# Generate answer
input_ids = tokenizer.encode(input_text, return_tensors="pt")
output = model.generate(input_ids, max_length=150, num_return_sequences=1)
answer = tokenizer.decode(output[0], skip_special_tokens=True)

Limitations

The model's knowledge is limited to its training data and the base GPT-2 model.
It may sometimes generate irrelevant or incorrect answers, especially for topics outside its training domain.
The model does not have access to external information or real-time data.

Ethical Considerations

Users should be aware that this model, like all language models, may reflect biases present in its training data. It should not be used as a sole source of information for critical decisions.

Future Improvements

Fine-tuning on a larger and more diverse dataset
Experimenting with larger base models (e.g., GPT-2 medium or large)
Implementing techniques to improve factual accuracy and reduce hallucinations
