Deeper Inquiries

In the context of hybrid question answering involving arithmetic operations, Large Language Models (LLMs) often face challenges in two main areas: incorrect extraction and incorrect reasoning.
Incorrect Extraction: This category includes errors where the model struggles to accurately identify and extract relevant information from the provided data for effective problem-solving. Subcategories under this include:
Missing/Incomplete Evidences: The model may fail to extract all necessary evidence required to derive the final answer.
Wrong Evidences: The model might extract incorrect values as supporting evidence from the premise.
Incorrect Reasoning: Errors in reasoning occur when the model has difficulty formulating an appropriate approach to solve a given problem. Sources of these errors can be:
Deficit in Domain Knowledge: When models use wrong formulas or measures due to lack of specific domain knowledge.
Question Misinterpretation: Errors arise when models interpret questions differently, leading to responses that do not align with the intended query.
These error types highlight where LLMs struggle in effectively handling complex mathematical tasks involving both structured tables and unstructured text.

There is indeed a risk of bias or inaccuracies being introduced by large language models during mathematical calculations. Some potential factors contributing to this risk include:
Insufficient Data Coverage: Large language models rely on training data for learning patterns and making predictions. If certain mathematical scenarios are underrepresented or absent in their training data, they may produce inaccurate results for such cases.
Implicit Biases: Language models can inadvertently learn biases present in their training data, which could influence their output during mathematical calculations.
Complexity Handling: Mathematical calculations involve intricate steps that require precise execution at each stage. Large language models may struggle with maintaining accuracy across multiple steps due to inherent limitations in processing complex numerical operations.
To mitigate these risks, thorough validation processes, diverse training datasets covering various scenarios comprehensively, and continuous monitoring for biases are essential when using large language models for mathematical tasks.

The prompting techniques employed in this study can be adapted and applied effectively across various domains beyond finance by tailoring them according to specific requirements:
Domain-Specific Prompting: Modify prompts based on domain-specific terminology and concepts relevant to different industries like healthcare, e-commerce, or scientific research.
Data Representation: Adjust prompts considering different types of structured data formats prevalent in diverse fields such as images (for medical imaging), code snippets (for programming tasks), or sensor readings (in IoT applications).
3Task Complexity Adaptation: Customize prompt structures based on varying levels of task complexity encountered across different domains; simpler prompts for basic queries and more elaborate ones for advanced problem-solving tasks.
By customizing prompting strategies according to distinct domain needs while ensuring alignment with specific task requirements outside finance-related contexts, these techniques can enhance performance and adaptability of large language models across a wide range of applications beyond financial document analysis."
