A digitally rendered abstract form resembling a cone or spiral with multiple layers that create a stepped pattern. The surface is smooth and features subtle shading with a monochromatic color scheme, primarily consisting of shades of gray. The structure appears to be floating against a dark gray background, emphasizing its intricate and geometric design.

This research requires GPT-4 fine-tuning because GPT-3.5 has limitations in handling complex time series data and topological data analysis. First, non-stationary time series data is high-dimensional and nonlinear, and GPT-3.5’s model capacity and processing capabilities may not meet the requirements. Second, the research requires the model to understand and generate mathematical formulas and algorithm descriptions related to topological data analysis, which demands higher language understanding and contextual reasoning abilities—areas where GPT-4 excels. Additionally, fine-tuning GPT-4 can better adapt it to the characteristics of complex time series data, enabling the generation of more precise and efficient analytical solutions. Therefore, GPT-4 fine-tuning is essential for the success of this research.
