UrduClassification
This model is a fine-tuned version of 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:
-
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.
-
Model Architecture: The "urduhack/roberta-urdu-small" pre-trained model was loaded as the base model for sequence classification using the RobertaForSequenceClassification class.
-
Training Arguments: The training arguments were set, including the number of training epochs, batch size, learning rate, evaluation strategy, logging strategy, and more.
-
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.
-
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.
-
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.
