# UrduClassification

This model is a fine-tuned version of [urduhack/roberta-urdu-small](https://huggingface.co./urduhack/roberta-urdu-small) on the imdb_urdu_reviews dataset.
It achieves the following results on the evaluation set:
- Loss: 0.4703

## Model Details

- Model Name: Urdu Sentiment Classification
- Model Architecture: RobertaForSequenceClassification
- Base Model: urduhack/roberta-urdu-small
- Dataset: IMDB Urdu Reviews
- Task: Sentiment Classification (Positive/Negative)

## Training Procedure
The model was fine-tuned using the transformers library and the Trainer class from Hugging Face. The training process involved the following steps:

1. Tokenization: The input Urdu text was tokenized using the RobertaTokenizerFast from the "urduhack/roberta-urdu-small" pre-trained model. The texts were padded and truncated to a maximum length of 256 tokens.

2. Model Architecture: The "urduhack/roberta-urdu-small" pre-trained model was loaded as the base model for sequence classification using the RobertaForSequenceClassification class.

3. Training Arguments: The training arguments were set, including the number of training epochs, batch size, learning rate, evaluation strategy, logging strategy, and more.

4. Training: The model was trained on the training dataset using the Trainer class. The training process was performed with gradient-based optimization techniques to minimize the cross-entropy loss between predicted and actual sentiment labels.

5. Evaluation: After each epoch, the model was evaluated on the validation dataset to monitor its performance. The evaluation results, including training loss and validation loss, were logged for analysis.

6. Fine-Tuning: The model parameters were fine-tuned during the training process to optimize its performance on the IMDb Urdu movie reviews sentiment analysis task.

### Training hyperparameters

The following hyperparameters were used during training:
- learning_rate: 5e-05
- train_batch_size: 16
- eval_batch_size: 16
- seed: 42
- optimizer: Adam with betas=(0.9,0.999) and epsilon=1e-08
- lr_scheduler_type: linear
- lr_scheduler_warmup_steps: 500
- num_epochs: 3

### Training results

| Training Loss | Epoch | Step | Validation Loss |
|:-------------:|:-----:|:----:|:---------------:|
| 0.4078        | 1.0   | 2500 | 0.3954          |
| 0.2633        | 2.0   | 5000 | 0.4007          |
| 0.1205        | 3.0   | 7500 | 0.4703          |

## Evaluation Results
The model was evaluated on an undisclosed dataset using a language modeling task. The evaluation results after 3 epochs of fine-tuning are as follows:

- Evaluation Loss: 0.3954
- Evaluation Runtime: 51.60 seconds
- Average Samples per Second: 96.89
- Average Steps per Second: 6.06
- Epoch: 3.0
