DeBERTa-ELL is an advanced natural language processing (NLP) project that leverages the power of the DeBERTa (Decoding-enhanced BERT with Disentangled Attention) model to automatically assess the language proficiency of high school English Language Learners (ELLs) based on their essays. This project aims to provide a reliable, efficient, and scalable solution for educators and researchers in the field of second language acquisition and assessment.

• Utilizes state-of-the-art DeBERTa model for text analysis
• Assesses multiple aspects of language proficiency:
  • Cohesion
  • Syntax
  • Vocabulary
  • Phraseology
  • Grammar
  • Conventions
• Implements multi-label stratified k-fold cross-validation for robust model evaluation
• Supports both training and inference modes
• Includes data preprocessing and augmentation techniques
• Provides detailed logging and model checkpointing

• Python 3.10+
• PyTorch 2.3+
• Transformers 4.37+

For a complete list of dependencies, please refer to the requirements.txt file.

1. Clone this repository:

   git clone https://github.com/arnavs04/deberta-ell.git
   cd deberta-ell

2. Create a virtual environment (optional but recommended):

   python -m venv venv
   source venv/bin/activate  # On Windows, use `venv\Scripts\activate`

3. Install the required packages:

   pip install -r requirements.txt

The training data is already in the data/feedback-prize-english-language-learning/ directory.

To train the model, run:

python train.py

You can modify the hyperparameters in the configs.py file.

To run inference on new data:

python inference.py

You can modify the hyperparameters in the configs.py file

This project uses the DeBERTa-v3-base model as the backbone for essay analysis. The model is fine-tuned on the task of multi-aspect proficiency assessment, with a custom head for multi-label regression.

The performance of the model was evaluated using Smooth L1 Loss for training and validation, and Mean Column-wise Root Mean Square Error (MCRMSE) score for the final evaluation. Below are the summarized results for each fold:
