## 🔍 What This Does
|
10 |
|
11 |
+
This model fine-tunes `UBC-NLP/MARBERTv2` on a custom Arabic dataset focused on **e-commerce intent classification**. It supports dialects like Egyptian, Gulf, and Levantine Arabic, and is particularly optimized for short, informal customer queries.
|
|
|
|
|
12 |
|
13 |
+
The process included:
|
14 |
|
15 |
+
* Splitting the data into training and evaluation sets
|
16 |
+
* Fine-tuning the base model for **8 epochs**
|
17 |
+
* Evaluating the model using standard classification metrics

## 📊 Evaluation
|
32 |
|
33 |
+
The model was evaluated on a **held-out test set** using standard classification metrics:
|
34 |
|
35 |
+
* **Accuracy:** `88.5%` — the percentage of correct predictions
|
36 |
+
* **F1-score (weighted):** `88.4%` — balances precision and recall across all classes
|
37 |
+
* **Eval Loss:** `0.63` — the lowest error rate across all runs
|
38 |
|
39 |
+
These results reflect a **stable, production-ready NLU model**.

## ⚠️ Bias, Risks, and Limitations
|
44 |
|
45 |
+
* This model was trained on a **custom e-commerce dataset**, so performance outside this domain (e.g., medical or legal queries) may drop.
|
46 |
+
* Intents that were underrepresented in the training set may be misclassified or ignored.
|
47 |
+
* While `MARBERTv2` supports multiple Arabic dialects, it may still struggle with **code-switching**, rare slang, or complex sarcasm.
|

## ✅ Why This Model is Trustworthy
|
52 |
+
|
53 |
+
* It provides clear code examples for how to use it
|
54 |
+
* It sets expectations transparently
|
55 |
+
* It shows strong evaluation results
|
56 |
+
* It gives credit to the base model (`MARBERTv2`)
