Studying the Role of Input-Neighbor Overlap in Retrieval-Augmented Language Models Training Efficiency

Ehsan Doostmohammadi, Marco Kuhlmann

Retrieval-augmented language models have demonstrated performance comparable to much larger models while requiring fewer computational resources. The effectiveness of these models…

How Reliable Are Automatic Evaluation Methods for Instruction-Tuned LLMs?

Ehsan Doostmohammadi, Oskar Holmström, Marco Kuhlmann

Work on instruction-tuned Large Language Models (LLMs) has used automatic methods based on text overlap and LLM judgments as cost-effective alternatives to human evaluation. In thi…

Surface-Based Retrieval Reduces Perplexity of Retrieval-Augmented Language Models

Ehsan Doostmohammadi, Tobias Norlund, Marco Kuhlmann +1

Augmenting language models with a retrieval mechanism has been shown to significantly improve their performance while keeping the number of parameters low. Retrieval-augmented mode…

On the Generalization Ability of Retrieval-Enhanced Transformers

Tobias Norlund, Ehsan Doostmohammadi, Richard Johansson +1

Recent work on the Retrieval-Enhanced Transformer (RETRO) model has shown that off-loading memory from trainable weights to a retrieval database can significantly improve language…

SINA-BERT: A pre-trained Language Model for Analysis of Medical Texts in Persian

Nasrin Taghizadeh, Ehsan Doostmohammadi, Elham Seifossadat +2

We have released Sina-BERT, a language model pre-trained on BERT (Devlin et al., 2018) to address the lack of a high-quality Persian language model in the medical domain. SINA-BERT…

Joint Persian Word Segmentation Correction and Zero-Width Non-Joiner Recognition Using BERT

Ehsan Doostmohammadi, Minoo Nassajian, Adel Rahimi

Words are properly segmented in the Persian writing system; in practice, however, these writing rules are often neglected, resulting in single words being written disjointedly and…
