Model Details: INT8 DistilBERT base uncased finetuned SST-2

This model is a fine-tuned DistilBERT model for the downstream task of sentiment classification, training on the SST-2 dataset and quantized to INT8 (post-training static quantization) from the original FP32 model ( distilbert-base-uncased-finetuned-sst-2-english ). The same model is provided in two different formats: PyTorch and ONNX.

Intended Use	Description
Primary intended uses	Inference for sentiment classification (classifying whether a statement is positive or negative)
Primary intended users	Anyone
Out-of-scope uses	This model is already fine-tuned and quantized to INT8. It is not suitable for further fine-tuning in this form. To fine-tune your own model, you can start with distilbert-base-uncased-finetuned-sst-2-english . The model should not be used to intentionally create hostile or alienating environments for people.

Load the PyTorch model with Optimum Intel

from optimum.intel.neural_compressor import INCModelForSequenceClassification

model_id = "Intel/distilbert-base-uncased-finetuned-sst-2-english-int8-static"
int8_model = INCModelForSequenceClassification.from_pretrained(model_id)

Load the ONNX model with Optimum:

from optimum.onnxruntime import ORTModelForSequenceClassification

model_id = "Intel/distilbert-base-uncased-finetuned-sst-2-english-int8-static"
int8_model = ORTModelForSequenceClassification.from_pretrained(model_id)

Factors	Description
Groups	Movie reviewers from the internet
Instrumentation	Text movie single-sentence reviews taken from 4 authors. More information can be found in the original paper by Pang and Lee (2005)
Environment	-
Card Prompts	Model deployment on alternate hardware and software can change model performance

Metrics	Description

Training and Evaluation Data	Description
Datasets	The dataset can be found here: datasets/sst2 . There dataset has a total of 215,154 unique phrases, annotated by 3 human judges.
Motivation	Dataset was chosen to showcase the benefits of quantization on an NLP classification task with the Optimum Intel and Intel® Neural Compressor
Preprocessing	The calibration dataloader is the train dataloader. The default calibration sampling size 100 isn't divisible exactly by batch size 8, so the real sampling size is 104.

Quantitative Analyses	Description
Unitary results	The model was only evaluated on accuracy. There is no available comparison between evaluation factors.
Intersectional results	There is no available comparison between the intersection of evaluated factors.

Ethical Considerations	Description
Data	The data that make up the model are movie reviews from authors on the internet.
Human life	The model is not intended to inform decisions central to human life or flourishing. It is an aggregated set of movie reviews from the internet.
Mitigations	No additional risk mitigation strategies were considered during model development.
Risks and harms	The data are biased toward the particular reviewers' opinions and the judges (labelers) of the data. Significant research has explored bias and fairness issues with language models (see, e.g., Sheng et al., 2021 , and Bender et al., 2021 ). Predictions generated by the model may include disturbing and harmful stereotypes across protected classes; identity characteristics; and sensitive, social, and occupational groups. Beyond this, the extent of the risks involved by using the model remain unknown.

Caveats and Recommendations
Users (both direct and downstream) should be made aware of the risks, biases and limitations of the model. There are no additional caveats or recommendations for this model.
