# XLM-R and EXLMR Model
|
| 19 |
|
| 20 |
+
## Model Overview
|
| 21 |
|
| 22 |
+
The **XLM-R** (Cross-lingual Language Model - RoBERTa) is a multilingual model trained on 100 languages. The **EXLMR** (Extended XLM-RoBERTa) is an extended version designed to improve performance on low-resource languages spoken in Ethiopia, including Amharic, Tigrinya, and Afaan Oromo.
|
| 23 |
|
| 24 |
+
## Model Details
|
| 25 |
|
| 26 |
+
- **Base Model**: XLM-R
|
| 27 |
+
- **Extended Version**: EXLMR
|
| 28 |
+
- **Languages Supported**: Amharic, Tigrinya, Afaan Oromo, and more
|
| 29 |
+
- **Training Data**: Trained on a large multilingual corpus
|
| 30 |
|
| 31 |
+
## Usage
|
| 32 |
|
|
|
|
| 33 |
|
| 34 |
+
EXLMR addresses tokenization issues inherent to the XLM-R model, such as out-of-vocabulary (OOV) tokens and over-tokenization, especially for low-resource languages.
|
| 35 |
+
Fine-tuning on specific datasets will help adapt the model to particular tasks and improve its performance.You can use this model with the `transformers` library for various NLP tasks.
|
| 36 |
+
```python
|
| 37 |
+
from transformers import AutoTokenizer, AutoModelForSequenceClassification
|
| 38 |
+
import torch
|
| 39 |
+
# Define the model checkpoint
|
| 40 |
+
checkpoint = "Hailay/EXLMR"
|
| 41 |
|
| 42 |
+
# Load the tokenizer and model
|
| 43 |
+
tokenizer = AutoTokenizer.from_pretrained(checkpoint)
|
| 44 |
+
model = AutoModelForSequenceClassification.from_pretrained(checkpoint)
|
| 45 |
+
|
| 46 |
+
|
| 47 |
+
EXLMR has been designed with specific support for underrepresented languages, particularly those spoken in Ethiopia (such as Amharic, Tigrinya, and Afaan Oromo). Like XLM-RoBERTa, EXLMR can be finetuned to handle multiple languages simultaneously, making it effective for cross-lingual tasks such as machine translation, multilingual text classification, and question answering.EXLMR-base follows the same architecture as RoBERTa-base, with 12 layers, 768 hidden dimensions, and 12 attention heads, totaling approximately 270M parameters.
