Model Card for Distilled INT8 Quantized TinyBERT (SST-2)

Model Details

Model Description

This model is a distilled and INT8-quantized TinyBERT fine-tuned for binary sentiment classification on the SST-2 dataset.
The goal of this model is energy-efficient and low-latency inference, making it suitable for on-device and edge deployment.

Starting from huawei-noah/TinyBERT_General_4L_312D, the model undergoes:

1. Knowledge Distillation to transfer task-specific knowledge
2. Post-training INT8 quantization to reduce memory footprint and inference cost

The result is a compact Transformer model that preserves competitive accuracy while significantly improving efficiency.

Uses

Direct Use

• Sentiment classification on short English text
• Low-power or latency-sensitive inference scenarios
• Benchmarking model compression and energy-aware NLP research

Out-of-Scope Use

• Multilingual sentiment analysis
• Long-document understanding
• Generative text tasks
• Safety-critical or high-stakes decision-making systems

---

Bias, Risks, and Limitations

• The model inherits dataset biases present in SST-2 (movie-review–centric sentiment).
• INT8 quantization may introduce minor numerical precision loss, particularly for out-of-distribution inputs.
• Performance may degrade on domains substantially different from movie reviews.

This model is intended for research and efficiency benchmarking, not for deployment in sensitive real-world applications without further validation.

How to Get Started with the Model

from transformers import AutoTokenizer, AutoModelForSequenceClassification
import torch

tokenizer = AutoTokenizer.from_pretrained("hamadbijarani012/<model-id>")
model = AutoModelForSequenceClassification.from_pretrained(
    "hamadbijarani012/<model-id>",
    torch_dtype=torch.int8
)

text = "The movie was surprisingly good!"
inputs = tokenizer(text, return_tensors="pt")
outputs = model(**inputs)
prediction = outputs.logits.argmax(dim=-1).item()
