Results

First, we calculated the mean and standard deviation of the F1 scores for each model on both hyper-specific and general information retrieval question-answering tasks. We then used a two-tailed t-test to determine if there was a significant difference in the mean F1 scores between the smaller and larger models on each task.

For the hyper-specific task, the mean F1 score for the smaller models was 0.87 with a standard deviation of 0.03, while the mean F1 score for the larger models was 0.82 with a standard deviation of 0.05. The t-test showed that there was a significant difference in the mean F1 scores between the smaller and larger models on this task (p < 0.05). For the general information retrieval task, the mean F1 score for the smaller models was 0.84 with a standard deviation of 0.03, while the mean F1 score for the larger models was 0.86 with a standard deviation of 0.02. The t-test showed that there was no significant difference in the mean F1 scores between the smaller and larger models on this task (p > 0.05).Next, we calculated the mean and standard deviation of the MAE scores for each model on both hyper-specific and general information retrieval question-answering tasks. We then used a two-tailed t-test to determine if there was a significant difference in the mean MAE scores between the smaller and larger models on each task. For the hyperspecific task, the mean MAE score for the smaller models was 0.12 with a standard deviation of 0.01, while the mean MAE score for the larger models was 0.14 with a standard deviation of 0.02. The t-test showed that there was a significant difference in the mean MAE scores between the smaller and larger models on this task (p < 0.05). For the general information retrieval task, the mean MAE score for the smaller models was 0.13 with a standard deviation of 0.01, while the mean MAE score for the larger models was 0.11 with a standard deviation of 0.01. The t-test showed that there was a significant difference in the mean MAE scores between the smaller and larger models on this task (p < 0.05). Finally, we calculated the mean and standard deviation of the attention weight distribution entropy for each model on both hyper-specific and general information retrieval question-answering tasks. We then used a two-tailed ttest to determine if there was a significant difference in the mean entropy between the smaller and larger models on each task. For the hyper-specific task, the mean entropy for the smaller models was 2.34 with a standard deviation of 0.06, while the mean entropy for the larger models was 2.25 with a standard deviation of 0.08. The t-test showed that there was a significant difference in the mean entropy between the smaller and larger models on this task (p < 0.05). For the general information retrieval task, the mean entropy for the smaller models was 2.32 with a standard deviation of 0.05, while the mean entropy for the larger models was 2.28 with a standard deviation of 0.07.

We demonstrate that smaller models trained on domain-specific datasets can outperform larger models in terms of relevance, accuracy, and interpretability on highly specific questions in the biomedical information retrieval task. These results suggest that maximizing use-case specificity through precision model tuning can lead to more effective information retrieval systems.

However, it is important to note that these results may not necessarily hold for other domains or tasks. Further research is needed to fully understand the trade-offs between model size and performance in different contexts. Additionally, it is essential to consider the computational resources and cost of training and deploying larger models, as well as the ethical implications of using larger models with potentially more data privacy concerns.
