# RAGPT: Fine-tuned GPT-2 for Context-Based Question Answering
|
10 |
+
|
11 |
+
## Model Description
|
12 |
+
|
13 |
+
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.
|
14 |
+
|
15 |
+
### Key Features
|
16 |
+
|
17 |
+
- Based on the GPT-2 small architecture (124M parameters)
|
18 |
+
- Fine-tuned on the "neural-bridge/rag-dataset-12000" dataset from Hugging Face
|
19 |
+
- Capable of generating answers based on provided context and questions
|
20 |
+
- Suitable for various question-answering applications
|
21 |
+
|
22 |
+
## Training Data
|
23 |
+
|
24 |
+
The model was fine-tuned using the "neural-bridge/rag-dataset-12000" dataset, which contains:
|
25 |
+
- Context passages
|
26 |
+
- Questions related to the context
|
27 |
+
- Corresponding answers
|
28 |
+
|
29 |
+
## Fine-tuning Process
|
30 |
+
|
31 |
+
The fine-tuning process involved:
|
32 |
+
1. Loading the pre-trained GPT-2 small model
|
33 |
+
2. Preprocessing the dataset to combine context, question, and answer into a single text
|
34 |
+
3. Training the model to predict the next token given the context and question
|
35 |
+
|
36 |
+
### Hyperparameters
|
37 |
+
|
38 |
+
- Base model: GPT-2 small
|
39 |
+
- Number of training epochs: 3
|
40 |
+
- Batch size: 4
|
41 |
+
- Learning rate: Default AdamW optimizer settings
|
42 |
+
- Max sequence length: 512 tokens
|
43 |
+
|
44 |
+
## Usage
|
45 |
+
|
46 |
+
To use the model:
|
47 |
+
|
48 |
+
```python
|
49 |
+
from transformers import AutoTokenizer, AutoModelForCausalLM
|
50 |
+
|
51 |
+
model_name = "BueormLLC/RAGPT"
|
52 |
+
tokenizer = AutoTokenizer.from_pretrained(model_name)
|
53 |
+
model = AutoModelForCausalLM.from_pretrained(model_name)
|
54 |
+
|
55 |
+
# Prepare input
|
56 |
+
context = "Your context here"
|
57 |
+
question = "Your question here"
|
58 |
+
input_text = f"Contexto: {context}\nPregunta: {question}\nRespuesta:"
|
59 |
+
|
60 |
+
# Generate answer
|
61 |
+
input_ids = tokenizer.encode(input_text, return_tensors="pt")
|
62 |
+
output = model.generate(input_ids, max_length=150, num_return_sequences=1)
|
63 |
+
answer = tokenizer.decode(output[0], skip_special_tokens=True)
|
64 |
+
```
|
65 |
+
|
66 |
+
## Limitations
|
67 |
+
|
68 |
+
- The model's knowledge is limited to its training data and the base GPT-2 model.
|
69 |
+
- It may sometimes generate irrelevant or incorrect answers, especially for topics outside its training domain.
|
70 |
+
- The model does not have access to external information or real-time data.
|
71 |
+
|
72 |
+
## Ethical Considerations
|
73 |
+
|
74 |
+
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.
|
75 |
+
|
76 |
+
## Future Improvements
|
77 |
+
|
78 |
+
- Fine-tuning on a larger and more diverse dataset
|
79 |
+
- Experimenting with larger base models (e.g., GPT-2 medium or large)
|
80 |
+
- Implementing techniques to improve factual accuracy and reduce hallucinations
