Model Card for RoBERTa-large-KazQAD-Informatics-fp16-lora

The KazRoBERTa-Large KazQAD model is an optimized variant of the RoBERTa model, specifically fine-tuned and adapted for question-answering tasks in the Kazakh language using the KazQAD dataset.

Model Details

Model Description

The model is designed to perform efficiently on question-answering tasks in Kazakh, demonstrating substantial improvements in metrics after fine-tuning and adaptation using LoRA.

• Developed by: Tleubayeva Arailym, Saparbek Makhambet, Bassanova Nurgul, Shomanov Aday, Sabitkhanov Askhat
• Model type: Transformer-based (RoBERTa)
• Language(s) (NLP): Kazakh (kk)
• License: apache-2.0
• Finetuned from model [optional]: nur-dev/roberta-large-kazqad

Uses

Direct Use

The model can directly answer questions posed in Kazakh, suitable for deployment in various NLP applications and platforms focused on Kazakh language understanding.

Downstream Use [optional]

Ideal for integration into larger applications, chatbots, and information retrieval systems for enhanced user interaction in Kazakh.

Out-of-Scope Use

Not recommended for:

• Tasks involving languages other than Kazakh without further adaptation.

• Critical decision-making systems without additional verification processes.

Bias, Risks, and Limitations

• Potential biases may arise from the underlying training data sources.

• Model accuracy may degrade when handling ambiguous or complex queries outside the training domain.

Recommendations

Users should consider additional fine-tuning or bias mitigation strategies when deploying the model in sensitive contexts.

Evaluation results

The evaluation of the model demonstrated significant improvements after fine-tuning and applying LoRA. The base model, before any modifications, showed an Exact Match (EM) score of 17.92% and an F1-score of 31.57%. These low scores indicate that the model had difficulty correctly identifying precise answers in its initial state.

After fine-tuning on the KazQAD dataset, the model's performance improved dramatically, with the EM score rising to 56.69% and the F1-score increasing to 69.70%. This represents a substantial increase of 316.2% in EM and 220.8% in F1-score, confirming that fine-tuning significantly enhances the model's ability to process and understand Kazakh-language questions accurately.

With the application of the LoRA adapter in a mixed precision (FP16) setup, the model maintained a strong improvement over the base version while being computationally more efficient. The LoRA-adapted model achieved an EM score of 37.79% and an F1-score of 56.07%, marking a 210.9% increase in EM and a 177.6% increase in F1-score compared to the original model. This adaptation allows for a balance between performance and resource efficiency, making it a viable option when computational constraints are a concern.
