Multilingual DistilBERT — ViClickbait-2025

Fine-tuned from distilbert-base-multilingual-cased for binary Vietnamese clickbait detection.

Experimental setup

• Input: headline paired with lead paragraph; no URL, source, category, publish time, image, or engagement metadata.
• Fixed 80/10/10 split using StratifiedGroupKFold with seed 42.
• Fine-tuning seeds: [42, 22, 202]; 3 epochs per seed.
• Development Macro-F1 selects checkpoints and representative seed.
• Weighted cross-entropy from training-label frequencies: True.
• Effective batch size: 8; max length: 256.

Results

Metric	Mean ± sample std
Test Macro-F1	0.7558 ± 0.0138
Test accuracy	0.7768 ± 0.0161
Dev Macro-F1	0.7427 ± 0.0104

Representative seed: 202, selected only by development Macro-F1.

Per-seed

seed	dev_macro_f1	test_macro_f1	test_accuracy
22	0.7475	0.7717	0.7953
42	0.7308	0.747	0.7661
202	0.7499	0.7488	0.769

Usage

from transformers import AutoModelForSequenceClassification, AutoTokenizer

model_id = "BaoNhan/distilbert-multilingual-ViClickbait-2025"
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForSequenceClassification.from_pretrained(model_id)
title = "Tiêu đề bài báo"
lead = "Đoạn dẫn của bài báo"
inputs = tokenizer(title, lead, return_tensors="pt", truncation=True, max_length=256)
prediction = model(**inputs).logits.argmax(dim=-1).item()
print(model.config.id2label[prediction])

Dataset

• Dataset: https://doi.org/10.17632/3wc46bfcjc.1

Limitations

The dataset is small, temporally bounded to 2023–2025, and collected from eight Vietnamese news platforms. Results may not transfer to social media, other publishers, or emerging clickbait styles.
