Introduction

The rapid expansion of IOT technologies has ushered in an era where vast quantities of data are generated continuously across various domains, including smart cities, healthcare, industrial automation, agriculture, and retail [1,2]. This explosion of data presents both unprecedented opportunities and significant challenges [3]. As IoT devices proliferate, the sheer volume, velocity, and variety of data produce necessitate advanced methodologies for effective analysis and model training [4]. The ability to leverage this data to gain actionable insights hinges on optimizing the analytical processes and techniques applied to IoT datasets [5].

A critical aspect of managing IoT data was understanding its intrinsic characteristics, which include high dimensionality and complexity [6]. IoT datasets often consist of numerous features collected at high frequency, resulting in data that was not only vast but also intricate [7]. The high-dimensional nature of this data poses challenges for traditional analytical methods, which struggle to process and interpret such complexity efficiently [8]. Furthermore, the presence of noise, errors, and inconsistencies within IoT data can significantly impact the accuracy of predictive models, necessitating sophisticated preprocessing and cleaning techniques to ensure data quality [9].
