Large Language Models (LLMs) and their Sensitivity Issues in Multiple-Choice Questions

Large Language Models (LLMs), with their exceptional capabilities, have risen in popularity across various fields, boasting an ability to outperform both supervised models and humans in a variety of instances. Yet, despite their growing adoption and use, studies have drawn attention to functional constraints in these models due to sensitivity issues that arise in prompt language and few-shot demonstrations.

One company dedicated to investigating this issue is Megagon Labs. Their research is committed to elevating the robustness of LLMs in handling multiple-choice questions—a task frequently employed in assessing an LLM’s abilities in fact retrieval and inference. A striking finding in the research conducted by Megagon Labs is the significant performance discrepancy, ranging from approximately 13% to 75%, which manifests when the order of the answer choices is rearranged.

The core hypothesis driving Megagon Labs’ research is that the sensitivity issues stem from the LLMs’ difficulty in discerning between the top-2 or top-3 prediction options. This issue, coupled with a positional bias resulting from the question’s phrasing, creates an inherent vulnerability to bias within these models.

Seeking to mitigate these biases, Megagon Labs has developed strategies targeting these weak points. By purposely accentuating bias—choosing the first and last options from the top choices, to highlight the LLMs’ favoritism—the team investigated how to counteract and diminish the impact of these biases. A series of experiments were designed and implemented to validate this strategic hypothesis.

To further enhance the efficiency of LLM predictions, Megagon Labs engineers built two differing calibration techniques into their models. Preliminary results show promising gains in forecast accuracy across several models and benchmarks. The calibration techniques serve to tackle the sensitivity issues that LLMs display when handling multiple-choice questions.

The team’s research delves into the extent of sensitivity in LLMs, focusing specifically on how the order of options in multiple-choice queries influences model responses. Experiments conducted using the GPT-4 model and InstructGPT on five different multiple-choice question (MCQ) benchmarks aimed to bring clarity to these questions.

Findings from Megagon Labs’ research suggest that Large Language Models’ functionality can be appreciably improved by tackling their sensitivity to multiple-choice question order and subsequent bias. The implications of these results are significant; their very premise could revolutionize the future use of LLMs in tasks requiring fact retrieval and inferencing.

However, for broader adoption, researchers, engineers, and AI enthusiasts alike must take a closer look at better understanding and overcoming these apparent sensitivity constraints in Large Language Models. As research progresses, and our understanding deepens, the strategies developed by Megagon Labs may well position LLMs to overcome their most significant hurdles.

In conclusion, it is essential to recognize the significance of Megagon Labs’ research in acknowledging and addressing the shortcomings of LLMs. Through innovative strategies and calibration techniques, the performance discrepancies, sensitivity issues, and positional biases that currently constrain these models can be effectively combatted. It’s a movement that’s helping us prepare for a future where artificial intelligence isn’t just capable but also reliable.

These results signal a greater understanding of LLMs and a step towards making Artificial Intelligence more dependable. As Megagon Labs continues to pioneer innovative solutions, the AI community will remain beholden to their exploration of novel improvements for Large Language Models.

Up until working with Casey, we had only had poor to mediocre experiences outsourcing work to agencies. Casey & the team at CJ&CO are the exception to the rule.

Communication was beyond great, his understanding of our vision was phenomenal, and instead of needing babysitting like the other agencies we worked with, he was not only completely dependable but also gave us sound suggestions on how to get better results, at the risk of us not needing him for the initial job we requested (absolute gem).

This has truly been the first time we worked with someone outside of our business that quickly grasped our vision, and that I could completely forget about and would still deliver above expectations.

I honestly can't wait to work in many more projects together!
