Abstract

Real-world data often present challenges such as imbalance, noise, and missing values. Recently, the Machine Learning literature has demonstrated that improving model performance also requires enhancing the quality of the data used for training, giving rise to a new research field known as Data-Centric Artificial Intelligence. Missing values, defined as the absence of information in one or more columns of a dataset, represent a common challenge in this context. The literature proposes various strategies to impute these values, ranging from simpler methods to advanced models based on Deep Learning. With the recent advancements in Generative Artificial Intelligence and Large Language Models (LLMs), new investigations have begun exploring the use of LLMs for missing value imputation. Therefore, this doctoral research proposal aims to investigate methodologies based on LLMs to perform missing data imputation efficiently and robustly from the perspective of Data-Centric AI. (AU)
