Machine learning: The cornerstone of data-driven decision making for sport organizations

This is an excerpt from Research Methods and Design in Sport Management-3rd Edition by Damon P.S. Andrew,Paul M. Pedersen.

By James Du, PhD, Yoseph Mamo, PhD, Bradley J. Baker, PhD

The field of sport management research has experienced a significant surge in the application of machine learning (ML; Du et al., 2024). This branch of artificial intelligence, designed to streamline and automate statistical learning processes, is increasingly becoming a cornerstone of data-driven decision making within the sport management domain (Mamo, 2023). By leveraging algorithms that learn from big data, discern patterns, and generate actionable insights, sophisticated decisions are now being executed with minimal reliance on human oversight.

While the roots of machine learning can be traced back to the 1950s when computer scientists first sought to create self-learning programs, recent technological breakthroughs have significantly expanded its usability. These advancements have made machine learning more practical, accessible, and relevant to the sport industry, empowering sport managers and scholars to harness diverse data sets for strategic advantage. To remain competitive, sport managers must navigate an increasingly complex landscape that demands not only operational efficiency but also strategic foresight. Machine learning, for instance, offers solutions that enable more precise customer targeting, refined marketing and sales forecasting, and greater fan engagement.

Watanabe et al. (2021) highlight that the integration of big data and artificial intelligence (AI) within sports extends beyond traditional areas such as performance metrics, talent scouting, or game analytics. In fact, a significant transformation is occurring on the business front, where sport organizations are increasingly adopting machine learning strategies to understand their fanbase and refine consumer preference profiles. As sport managers navigate this evolving landscape, it is becoming increasingly challenging for sport management scholars to ignore the vast opportunities presented by the proliferation of big data and the advancements in machine intelligence (Naraine and Wanless, 2020).

Far from being merely analytical tools, machine learning offers a transformative potential for research in sport management. Scholars now recognize that this analytical tool can be leveraged to tackle complex questions that were previously beyond reach. The true value of machine learning lies not only in its capacity for data analysis, but also in its ability to merge theoretical frameworks with cutting-edge computational methods, thereby deepening our understanding and driving the next wave of knowledge creation (Mamo et al., 2022).

OVERVIEW OF MACHINE LEARNING IN SPORT MANAGEMENT RESEARCH

A Primer in Machine Learning (ML)

The term “machine learning” (ML) is frequently misunderstood and used interchangeably with notions of highly advanced systems that mimic human cognition and consciousness. However, this oversimplification distorts the reality of what ML truly entails. Machine learning is a transformative branch of artificial intelligence that enables systems to learn from data, identify patterns, and make decisions with minimal human intervention. At its core, machine learning involves deriving insights from data and refining procedures, either autonomously or with limited human oversight (Khine, 2024). Though the term evokes images of sophisticated artificial intelligence, its real-world applications are far more routine and narrowly focused. One of the most familiar examples of ML’s integration into sports is the recommendation engines that power fan experiences on social media platforms.

Originating in the early 1950s, machine learning represents an evolution of artificial intelligence (AI), which refers to the development of computer systems capable of performing tasks that typically require human intelligence. AI aims to replicate human cognitive tasks through automation (Chollet, 2018). Early pioneers in the field believed that replicating human-level intelligence was a matter of crafting a detailed set of algorithms based on explicit knowledge, known as symbolic AI. Despite its promise, symbolic AI struggled to effectively address complex, ambiguous challenges such as image classification, speech recognition, and text processing. It was out of these limitations that machine learning emerged, redefining the landscape of artificial intelligence and ushering in a new era of technological advancement.

Machine Learning Flowchart
The flowchart in figure 21.1 illustrates the iterative nature of machine learning development, underscoring a cyclical process of testing, refinement, and continuous optimization. The process begins with the identification of the target problem, followed by data collection. This data then undergo a screening and cleansing phase to address inconsistencies, outliers, and missing values. With a refined dataset in hand, the next step is model selection. The appropriate algorithm is selected based on the problem’s specific characteristics. For instance, at this stage, a machine learning algorithm is selected to make predictions or classifications. Based on the collected input data, whether labeled or unlabeled, the chosen algorithm will generate an estimate reflecting patterns within the data. Next, the selected model is trained to extract insights, and its efficacy is evaluated through model assessment. Here, an error or loss function is applied to estimate the model’s predictive accuracy. When known examples are available, the loss function enables a comparison to determine the model’s accuracy. If the model better fits the data points in the training set, weight adjustments are made to minimize discrepancies between the known examples and the model’s estimates. If the model’s performance proves unsatisfactory, the process loops back for parameter tuning or model re-selection. The algorithm repeats this iterative cycle of evaluation and optimization, autonomously adjusting weights until a specified accuracy threshold is reached. Upon achieving satisfactory performance in the testing
phase, the model advances to deployment readiness. Once the predetermined criteria are met, the model is deployed to generate predictions or support decision making. If further refinement is necessary, a feedback loop iteratively ensures sustained model performance, facilitating the integration of new data and adapting to evolving analytical requirements.
