distilroberta-finetuned-eli5

This model is a fine-tuned version of distilroberta-base, optimized for the ELI5 (Explain Like I'm Five) task. It has been trained on the eli5_category dataset to handle masked language modeling specifically within the context of question answering and explanations.

Model Description

DistilRoBERTa is a smaller, faster, and lighter version of the RoBERTa model, designed to retain a good balance between efficiency and performance. This fine-tuned model adapts DistilRoBERTa to the ELI5 task, which involves understanding complex topics and providing simplified, easy-to-understand explanations. The model has been fine-tuned using masked language modeling objectives, making it suitable for tasks requiring contextual understanding and natural language generation.

Key Features:

• Base Model: distilroberta-base, a distilled version of the robustly optimized BERT approach (RoBERTa).
• Fine-Tuned For: ELI5 (Explain Like I'm Five) tasks, where the goal is to generate simple and coherent explanations for complex topics.
• Architecture: Transformer-based with 6 layers, 768 hidden units, and 12 attention heads, making it lighter and faster than full-scale RoBERTa models.

Intended Uses & Limitations

Intended Uses:

• Text Completion: Generate text that completes a given sentence or passage, particularly for educational or explanatory content.
• Simplified Explanations: Generate explanations for complex topics that are easy to understand.
• Masked Language Modeling: Predict masked words in a sentence, making it useful for filling in blanks and understanding context.

Limitations:

• Domain-Specific Knowledge: The model's understanding is limited to the domains present in the training data. It may not perform well on highly specialized or technical topics not covered during training.
• Output Quality: Although the model can generate coherent text, the quality and accuracy of its explanations may vary. Users should verify and refine the outputs, especially for critical applications.
• Biases: As with all language models, this model may exhibit biases present in the training data. Care should be taken when using it in sensitive or diverse contexts.

Training and Evaluation Data

Dataset:

• Training Data: The model was fine-tuned on the eli5_category dataset, which contains question-answer pairs and explanatory text sourced from the ELI5 subreddit and other similar data. This dataset focuses on providing simplified explanations for various topics, making it suitable for the ELI5 task.
• Evaluation Data: The model was evaluated on a separate validation set derived from the same dataset to ensure consistency in the type of questions and explanations.

Data Characteristics:

• Topics Covered: A wide range of topics, including science, technology, health, and general knowledge.
• Language: Primarily English.
• Data Size: The dataset consists of thousands of question-answer pairs, providing a robust training ground for learning explanatory language patterns.

Usage

You can use this model in a Hugging Face pipeline for fill-mask tasks:

from transformers import pipeline

fill_mask = pipeline(
    "fill-mask", model="ashaduzzaman/distilroberta-finetuned-eli5"
)

# Example usage
text = "The quick brown <mask> jumps over the lazy dog."
fill_mask(text, top_k=3)
