DistilBERT Fine-Tuned on SQuAD for Extractive QA

Model Description

DistilBERT base uncased fine-tuned on a 5,000-sample subset of SQuAD for extractive question answering.

Training Details

• Base model: distilbert-base-uncased
• Dataset: SQuAD (5,000 samples, 80/20 train/test split)
• Epochs: 3
• Learning rate: 2e-5
• Batch size: 16
• Training loss: 2.303
• Device: Apple Silicon (MPS)

Usage

from transformers import AutoTokenizer, AutoModelForQuestionAnswering
import torch

tokenizer = AutoTokenizer.from_pretrained("John-Machado/distilbert-squad-qa")
model = AutoModelForQuestionAnswering.from_pretrained("John-Machado/distilbert-squad-qa")

question = "How many official league titles has Juventus won?"
context = "The club has won 36 official league titles, 14 Coppa Italia titles and nine Supercoppa Italiana titles."

inputs = tokenizer(question, context, return_tensors="pt")
with torch.no_grad():
    outputs = model(**inputs)

start = outputs.start_logits.argmax()
end = outputs.end_logits.argmax()
answer = tokenizer.decode(inputs.input_ids[0, start : end + 1])
print(answer)  # "36"

Limitations

• Trained on only 5,000 SQuAD samples (out of 87,599) as a learning exercise
• Answers must exist as a verbatim substring in the context
• Cannot synthesize answers across multiple passages
