# XLM-R_WR: XLM-RoBERTa Telugu Sentiment Classification Model (With Rationale) |
|
|
|
|
|
## Model Overview |
|
|
|
|
|
**XLM-R_WR** is a Telugu sentiment classification model based on **XLM-RoBERTa (XLM-R)**, a general-purpose multilingual transformer developed by Facebook AI. |
|
|
The "WR" in the model name stands for "**With Rationale**", indicating that this model is trained using both sentiment labels and **human-annotated rationales** from the TeSent_Benchmark-Dataset. |

|
## Model Details |
|
|
|
|
|
- **Architecture:** XLM-RoBERTa (transformer-based, multilingual) |
|
|
- **Pretraining Data:** 2.5TB of filtered Common Crawl data across 100+ languages, including Telugu |
|
|
- **Pretraining Objective:** Masked Language Modeling (MLM), no Next Sentence Prediction (NSP) |
|
|
- **Fine-tuning Data:** [TeSent_Benchmark-Dataset](https://huggingface.co/datasets/dsl-13-srmap/tesent_benchmark-dataset), using both sentence-level sentiment labels and rationale annotations |
|
|
- **Task:** Sentence-level sentiment classification (3-way) |
|
|
- **Rationale Usage:** **Used** during training and/or inference ("WR" = With Rationale) |
|
|

|
## Intended Use |
|
|
|
|
|
- **Primary Use:** Benchmarking Telugu sentiment classification on the TeSent_Benchmark-Dataset, especially as a **baseline** for models trained with and without rationales |
|
|
- **Research Setting:** Suitable for cross-lingual and multilingual NLP research, as well as explainable AI in low-resource settings |

## Why XLM-R? |
|
|
|
|
|
XLM-R is designed for cross-lingual understanding and contextual modeling, providing strong transfer learning capabilities and improved downstream performance compared to mBERT. When fine-tuned with local Telugu data, XLM-R delivers solid results for sentiment analysis. |
|
|
However, Telugu-specific models like MuRIL or L3Cube-Telugu-BERT may offer better cultural and linguistic alignment for purely Telugu tasks. |

## Performance and Limitations |
|
|
|
|
|
**Strengths:** |
|
|
- Strong transfer learning and contextual modeling for multilingual NLP |
|
|
- Good performance for Telugu sentiment analysis when fine-tuned with local data |
|
|
- Provides **explicit rationales** for predictions, aiding explainability |
|
|
- Useful as a cross-lingual and multilingual baseline |
|
|
|
|
|
**Limitations:** |
|
|
- May be outperformed by Telugu-specific models for culturally nuanced tasks |
|
|
- Requires sufficient labeled Telugu data and rationale annotations for best performance |
|
