Abstract: Technological advancement progresses rapidly while the quantity of data generated from multiple sources especially those linked to human activities expands creating a necessity for strong frameworks to conduct stream data analysis and identify outliers. This article initiates a detailed exploration into the role these analytical frameworks play in identifying statistically significant outliers that deviate from expected patterns within extensive datasets. The numerous traditional methods for detecting outliers encounter major difficulties when processing streaming data because of its vast volume and rapid speed which leads to computational inefficiencies that make these methods unsustainable for real-time applications [1]. The realm of stream analytics addresses these challenges through its capability to process data points as they arrive which leads to enhanced decision-making power by obtaining immediate insights [2]. The pursuit of detecting anomalies within human activity datasets represents a critical endeavor because these anomalies possess potential implications that extend across multiple applications such as health monitoring systems and security networks. The present study examines contemporary challenges such as excessive memory usage alongside dimensionality issues which complicate outlier detection within large data streams [3]. This article embarks on an exploration into how contemporary methodologies and frameworks crafted for real-time analysis empower stream data processing advancements to reach heightened precision in detecting human behavioral anomalies. The progression of these technological advancements serves to deepen our understanding of normal activity patterns while at the same time laying down essential initial steps for developing proactive responses to detected anomalies [4]. Our detailed investigation into specialized frameworks and techniques for outlier detection reveals the necessity for ongoing research to address emerging challenges while improving stream data analytics performance in the rapidly evolving digital landscape.
