Introduction

I. INTRODUCTION

Data fitting is a cornerstone of data analysis and machine learning, traditionally involving multiple parameters to capture the complexity of the data. However, certain scenarios necessitate the use of models with only one parameter, driven by the need for simplicity, ease of interpretation, or computational efficiency. In fields such as physics, economics, and biology, where models need to be both interpretable and computationally tractable, single-parameter models can provide significant advantages.

This paper investigates methods to fit any dataset using a single parameter, exploring theoretical underpinnings, practical techniques, and various applications. We delve into the mathematical foundations that allow for the reduction of model complexity without substantial loss of accuracy. Practical techniques, including parameter estimation and optimization, are examined to showcase how these models can be effectively applied in real-world scenarios.

Furthermore, we present case studies across diverse domains to illustrate the utility and limitations of one-parameter models. By understanding these methods, we aim to highlight the trade-offs between model simplicity and fit accuracy. Our goal is to provide a comprehensive overview that underscores the potential of single-parameter models to offer a balance between simplicity and performance.

1. LITERATURE REVIEW

In the field of data fitting, achieving simplicity without losing accuracy is an ongoing challenge. Traditional models often require multiple parameters to capture the nuances of data, which can lead to increased complexity and computational burdens. However, a growing body of research is focused on minimalist approaches, particularly those that utilize a single parameter for effective data fitting. The philosophical principle of Occam's Razor, which favors simplicity in scientific models, underpins the rationale for one-parameter solutions. Grunwald and Vitányi's (2004) exploration of the minimum description length (MDL) principle highlights the preference for simpler models that adequately explain data. Mathematically, one-parameter models often utilize straightforward functional forms like linear or power-law distributions, recognized for their simplicity and robustness (Newman, 2005).

Practical applications of one-parameter models span various fields. In geophysics, power-law distributions have been effectively used to model earthquake magnitudes and spatial distributions, providing critical insights with minimal computational effort (Turcotte, 1997). In biological sciences, the one-parameter logistic function introduced by Laird (1964) to describe bacterial growth rates is widely adopted due to its ease of use and clear interpretability. Similarly, in economics, the Pareto distribution, which uses a single parameter to describe income and wealth distributions, demonstrates the utility of minimalist models in capturing complex social phenomena (Pareto, 1896).

One-parameter models offer several comparative advantages. They are computationally efficient, making them suitable for large-scale data analysis and real-time applications where computational resources are limited (Hastie, Tibshirani, & Friedman, 2009). Additionally, their simplicity enhances interpretability, crucial for fields where understanding the model's inner workings is as important as its predictive power, such as healthcare and policy-making (Lipton, 2016). Furthermore, with fewer parameters, these models are less prone to overfitting, which enhances their robustness and generalization capabilities (Burnham & Anderson, 2002).

II. PROBLEM DEFINITION

The increasing complexity and volume of data in various fields necessitate effective and efficient data fitting methods. Traditional multi-parameter models, while capable of capturing detailed data patterns, often suffer from significant drawbacks such as increased computational demands, overfitting, and reduced interpretability. These issues pose a considerable challenge for real-time applications and large-scale data analysis, where simplicity and speed are crucial. Moreover, complex models can be difficult to interpret and apply in domains that require transparency and ease of understanding, such as healthcare, policy-making, and social sciences.

The primary problem addressed in this study is the need for data fitting models that balance simplicity and accuracy, reducing computational complexity without sacrificing predictive performance. Specifically, the focus is on exploring and validating one-parameter models that can effectively fit data across various applications. These models should demonstrate robustness to overfitting, computational efficiency, and ease of interpretability. The goal is to identify and refine minimalist approaches that can be widely applied, offering practical solutions to the challenges faced by traditional multi-parameter models.

By addressing this problem, the study aims to contribute to the development of more efficient data fitting techniques that are not only theoretically sound but also practically viable across diverse domains. This involves investigating the theoretical foundations of one-parameter models, evaluating their performance in different practical scenarios, and exploring recent advancements that enhance their applicability and accuracy. The outcome is expected to provide a comprehensive understanding of the benefits and limitations of one-parameter models, paving the way for their broader adoption in data-driven decision-making processes.
