A Mathematical Model of Delay Discounting & Bi-Faceted Impulsivity | #Sciencefather

Image
Introduction Delay discounting models have traditionally been grounded in frameworks such as the exponential model, hyperbolic model, and those stemming from nonextensive statistics. These models typically simplify impulsivity into a singular construct, thereby overlooking the complex and multifaceted nature of impulsive behavior. The present research introduces a new perspective by treating impulsivity not as a single parameter but as a dynamic interaction of multiple facets. By doing so, the study paves the way for more accurate predictions of behavioral decision-making and aligns mathematical modeling with real-world psychological complexity. Impulsivity as a multi-faceted construct Impulsivity is increasingly understood as a heterogeneous trait, encompassing both stable personality dimensions and fluctuating state-dependent behaviors. In this research, two distinct but complementary facets of impulsivity are mathematically represented, reflecting the nuanced differences between lon...

Contexts Matter: Robot-Aware 3D Human Motion Prediction for Agentic AI | Sciencefather #AI #Robotics

Image
Introduction Agentic AI-integrated robots play a vital role in achieving effective, efficient, and safe Human-Robot Collaboration (HRC). For seamless collaboration, robots must interpret and predict human behaviors accurately by understanding the working context. While many existing human motion prediction models emphasize task-related context, they often neglect the influence of the robot itself as a contextual factor. This research addresses that gap by exploring the integration of robot-awareness into prediction frameworks, paving the way for more intelligent and adaptive HRC systems. Background and Motivation Human motion prediction is a critical component in enabling real-time decision-making for collaborative robots. Traditional models predominantly focus on external environmental or task-specific parameters, often overlooking the direct impact of the robot’s actions. Such limitations can lead to inefficiencies or safety concerns in HRC. Motivated by the need for a more holist...
