Additionally, the models were pre-trained on larger datasets, including the entire parallel corpora, to provide a richer context and leverage a broader range of linguistic patterns and cultural nuances . The data pre-processing involved removing corpus-specific annotations, URLs, emoticons, and converting all text to lowercase to ensure the models focus on the linguistic structures and cultural nuances of the Egyptian-Arabic language . The primary approach involved using large language models (LLMs) such as LLaMA3 8B, Gemma1.1 2B, and Gemma1.1 7B, which were trained to follow human instructions and were decode-based architectures suitable for sequential tasks like machine translation. These models were trained using 2 T4 GPUs with 16GB VRAM to produce culturally fitting translations capturing the nuances of Egyptian-Arabic language and culture .
Q6. What is the dataset used for quantitative evaluation? Is the code open source?
The dataset used for quantitative evaluation is called "ArzEn-MultiGenre," which is an aligned parallel dataset of Egyptian Arabic song lyrics, novels, and subtitles with English translations . The code for this dataset is not explicitly mentioned as open source in the provided context.
Q7. Do the experiments and results in the paper provide good support for the scientific hypotheses that need to be verified? Please analyze.
The experiments and results presented in the paper provide strong support for the scientific hypotheses that needed verification.
