This is a 20-label Arabic university intent classifier fine-tuned from UBC-NLP/MARBERTv2. It routes one question to zero, one, or several university-information labels. The model uses masked_mean pooling and independent sigmoid outputs; it is not a generative model.

Model details

Architecture: UBC-NLP/MARBERTv2 encoder + dropout + linear multi-label head
Pooling: masked_mean
Maximum input length: 256 tokens
Model release: v0.4.0
Release lifecycle: preview
Weights: SafeTensors
Training data: NajahUniv/arabic-univeristy-chatbot-qa
Dataset release: v0.2.0
Pinned dataset revision: 61e566c16bda36d1a04184b2bb43df61b2989070
Decision thresholds: selected on validation data and stored in config.json and thresholds.json

The repository includes custom Transformers modeling code so it loads through the standard AutoClass API. Review the code in this repository before enabling trust_remote_code; in a production deployment, pin revision to a reviewed model commit SHA.

Release notes

v0.4.0 retrains the classifier on dataset release v0.2.0, which merges the earlier synthetic source with newly generated rows. The release adds Hebrew and Arabizi coverage, translated paraphrases alongside reworded ones, and repaired language metadata. The label taxonomy is unchanged; thresholds are retuned for the new weights.

Evaluation

Split	Macro F1	Micro F1	Subset accuracy	LRAP
Validation	0.9662	0.9666	0.9378	0.9735
Test	0.9616	0.9631	0.9302	0.9694

Threshold selection used only the validation split. The test split remained held out until the final comparison. Full aggregate and per-label results are available in validation_metrics.json and test_metrics.json.

Measured on Apple M5 Max (PyTorch 2.13.0, Transformers 5.14.1). Each batch size used 5 warm-up and 30 measured iterations over the same deterministically shuffled questions derived from the test split of NajahUniv/arabic-univeristy-chatbot-qa@v0.2.0, pinned to commit 61e566c16bda36d1a04184b2bb43df61b2989070, after applying the repository's standard dataset-preparation pipeline.

Numbers include tokenization, padding, device transfer, model forward pass, sigmoid, thresholding, and result construction. They exclude model loading and HTTP overhead. Latency and throughput depend on hardware, software versions, input lengths, batch size, and thermal state; compare only rows from this same run. Peak RSS is whole-process memory and MPS uses unified memory.

The full machine-readable benchmark report is included as benchmark_results.json. Use the direct benchmark for model-to-model speed comparisons; use the FastAPI load test below to size a specific deployment.

Optional CPU INT8 server inference

The onnx/ directory contains a dynamic-shape, dynamic-INT8 ONNX model for CPUExecutionProvider. It is a deployment alternative, not a replacement for the canonical SafeTensors checkpoint. onnx/onnx_config.json pins the graph checksum, label order, thresholds, runtime contract, numerical-verification report, and full validation-set quantization report. Its decision threshold is recalibrated on the validation split for the quantized logits; the SafeTensors checkpoint continues to use the canonical threshold in config.json. Use MODEL_BACKEND=onnx MODEL_PRECISION=int8 in the included FastAPI example. The conservative auto default retains PyTorch/SafeTensors on every device because INT8 speedups depend on the server CPU's instruction set and workload; benchmark before enabling it in production.

Validation result	FP32 ONNX	INT8 ONNX
Graph size	620.8 MiB	377.5 MiB
Macro F1	0.9662	0.9644
Micro F1	0.9666	0.9646
Decision threshold	canonical	0.30

The measured macro-F1 change after INT8 threshold recalibration is +0.0018 (positive means a drop). See onnx/quantization_report.json for source-threshold results, logit differences, and local latency.

Private browser inference (WebGPU and WASM CPU)

The webgpu/ directory contains a verified, fixed-shape ONNX Runtime Web model for private, client-side inference. It uses Q8 linear weights and Q4 embedding weights, batch size 1, and the same saved per-label thresholds as the Transformers model. Load webgpu/webgpu_config.json first; it records the graph checksum, tokenizer artifacts, input contract, and validation report. Applications can execute the same graph with ONNX Runtime Web's WebGPU provider or its WASM CPU provider. WASM is more broadly compatible but can be substantially slower. A privacy-preserving fallback should try WASM locally and require explicit consent before switching to server inference.

Install the browser libraries with:

npm install @huggingface/transformers onnxruntime-web

Run inference inside a Web Worker so model loading does not block the page. This WebGPU example loads the pinned release and applies the saved per-label thresholds from webgpu_config.json:

javascript

import { AutoTokenizer } from "@huggingface/transformers";
import * as ort from "onnxruntime-web/webgpu";

ort.env.wasm.wasmPaths = "/ort/"; // Serve matching ORT Web helper files here.
const executionProviders = ["webgpu"];

const modelId = "NajahUniv/AraUni-MARBERTv2-Intent-Classifier";
const revision = "v0.4.0";
const artifactRoot =
  `https://huggingface.co/${modelId}/resolve/${revision}/webgpu/`;
const config = await fetch(`${artifactRoot}webgpu_config.json`).then((response) => {
  if (!response.ok) throw new Error(`Could not load browser config: ${response.status}`);
  return response.json();
});
const tokenizer = await AutoTokenizer.from_pretrained(modelId, { revision });
const session = await ort.InferenceSession.create(
  `${artifactRoot}${config.model_file}`,
  { executionProviders, graphOptimizationLevel: "all" },
);

const text = "ما هي شروط القبول في الجامعة؟";
const encoded = await tokenizer(text, {
  padding: "max_length",
  truncation: true,
  max_length: config.max_length,
});
const feeds = Object.fromEntries(
  config.input_names.map((name) => [
    name,
    new ort.Tensor("int64", encoded[name].data, encoded[name].dims),
  ]),
);
const output = await session.run(feeds);
const logits = output[config.output_name].data;
const predictions = config.labels.map((label, index) => {
  const score = 1 / (1 + Math.exp(-Number(logits[index])));
  const threshold = Number(config.thresholds[label]);
  return { label, score, threshold, selected: score >= threshold };
});
console.table(predictions);

For private CPU execution, put the same shared inference code in a separate worker and change the runtime setup to:

javascript

import * as ort from "onnxruntime-web/wasm";

ort.env.wasm.wasmPaths = "/ort/";
ort.env.wasm.numThreads = 1; // Works without cross-origin isolation.
const executionProviders = ["wasm"];

Pass executionProviders to InferenceSession.create. Copy the matching ONNX Runtime Web .mjs and .wasm files from node_modules/onnxruntime-web/dist/ to the public /ort/ directory. Keep WebGPU and WASM in separate workers/bundles; do not assume that adding "wasm" after "webgpu" in one provider list provides a compatible fallback for every quantized operator. If WebGPU fails, start the WASM worker explicitly. Only switch to a server runtime after obtaining user consent.

This is multi-label classification: apply sigmoid independently to every logit, compare each score with that label's saved threshold, and allow zero, one, or several labels to be selected. The sigmoid scores are ranking/confidence signals and are not guaranteed to be calibrated probabilities.

Basic usage

python

import torch
from transformers import AutoModelForSequenceClassification, AutoTokenizer

model_id = "NajahUniv/AraUni-MARBERTv2-Intent-Classifier"
model_revision = "v0.4.0"
tokenizer = AutoTokenizer.from_pretrained(
    model_id,
    revision=model_revision,
    trust_remote_code=True,
)
model = AutoModelForSequenceClassification.from_pretrained(
    model_id,
    revision=model_revision,
    trust_remote_code=True,
).eval()

text = "ما هي شروط القبول في الجامعة؟"
inputs = tokenizer(text, return_tensors="pt", truncation=True, max_length=model.config.max_length)
with torch.inference_mode():
    probabilities = torch.sigmoid(model(**inputs).logits[0])

result = {}
for index, probability in enumerate(probabilities.tolist()):
    label = model.config.id2label[index]
    threshold = model.config.thresholds[label]
    result[label] = {"probability": probability, "selected": probability >= threshold}

selected_labels = [label for label, value in result.items() if value["selected"]]
print(selected_labels)

FastAPI hosting

The included service loads the model once, supports batching, uses MPS automatically on Apple Silicon, and optionally requires a bearer token:

bash

pip install -r requirements.txt
MODEL_ID=NajahUniv/AraUni-MARBERTv2-Intent-Classifier MODEL_REVISION=v0.4.0 MODEL_BACKEND=auto \
  MODEL_PRECISION=auto MODEL_API_KEY=change-me \
  uvicorn examples.fastapi_app:app --host 0.0.0.0 --port 8000

bash

curl http://localhost:8000/classify \
  -H 'Content-Type: application/json' \
  -H 'Authorization: Bearer change-me' \
  -d '{"texts":["كيف يمكنني دفع الرسوم؟"],"top_k":5}'

In Swagger UI at http://localhost:8000/docs, click Authorize and enter only the MODEL_API_KEY value (change-me in the example). Swagger adds the Bearer prefix.

For public production hosting, also add TLS, request-size/rate limits, monitoring, and a pinned MODEL_REVISION commit SHA. On macOS, use one Uvicorn worker so multiple processes do not each load a separate copy of the model into memory.

Intended use and limitations

The model is intended for routing Arabic university-chatbot questions within the label taxonomy above. It should not be treated as an authoritative source of admissions, academic, payment, or policy advice. The training data is task-specific; consult the pinned dataset release for its synthetic and real-user composition. The strong held-out scores may not transfer to other universities, taxonomies, dialect distributions, spelling patterns, or production traffic. Inputs outside the training distribution can still receive confident scores. Evaluate on real, independently collected traffic and add human fallback/escalation before deployment. The sigmoid values are classification scores, not guaranteed calibrated probabilities.
