Optimality Deviation using the Koopman Operator

CoRR
This paper investigates the impact of approximation error in data-driven optimal control problem of nonlinear systems while using the Koopman operator. While the Koopman operator enables a simplified representation of nonlinear dynamics through a lifted state space, the presence of approximation error inevitably leads to deviations in the computed ...

Where Is the Take in Give and Take? A Review of Empathy Effects on Workplace Outcomes for Both Givers and Receivers

Journal of Organizational Behavior, EarlyView.
ABSTRACT There is increasing interest in understanding and recognition of the importance of empathy effects at work. However, despite the two‐party nature of empathy, little research has distinguished between empathy‐giving versus empathy‐receiving, or between empathy‐giver versus receiver.

Data-Driven Dynamic State Estimation Framework Using a Koopman Operator-Based Linear Predictor

IEEE Access
Dynamic state estimation (DSE) is a fundamental task in many fields, including control systems, robotics, and signal processing. Traditional DSE methods, which rely on mathematical models to describe system dynamics, are often limited in their ...

Emotional Ambivalence Contextualized: The Antecedents and Consequences of Daily Affective Profiles During Pregnancy

Journal of Organizational Behavior, EarlyView.
ABSTRACT Research has increasingly highlighted the prevalence of emotionally ambivalent experiences for employees at work, with several self‐regulatory benefits emerging. Yet we do not have a full understanding of which work‐related contexts yield generative or maladaptive consequences of emotional ambivalence.

Glocal Hypergradient Estimation with Koopman Operator

CoRR
Gradient-based hyperparameter optimization methods update hyperparameters using hypergradients, gradients of a meta criterion with respect to hyperparameters. Previous research used two distinct update strategies: optimizing hyperparameters using global hypergradients obtained after completing model training or local hypergradients derived after every ...

Her Vision Guiding Him Toward Change: The Interactive Effects of Visionary Leadership, Leader Gender, and Follower Gender

Journal of Organizational Behavior, EarlyView.
ABSTRACT Visionary leadership is widely regarded as an effective tool for motivating followers. However, two influential theories make opposing predictions about what happens when women enact agentic leadership behavior. Role congruity theory predicts that such behavior can produce backlash effects, whereas expectancy violation theory predicts ...

Functional dimensionality of Koopman eigenfunction space

Results in Applied Mathematics
This work presents the general form solution of Koopman Partial Differential Equation for an autonomous system of N ordinary differential equations. We identify a domain in RN for which any number in the complex plane is an eigenvalue of the Koopman ...

Boundedness of Composition Operators in Orlicz–Morrey Spaces

Mathematische Nachrichten, EarlyView.
ABSTRACT In this paper, we investigate the necessary and sufficient conditions for the boundedness of composition operators on Orlicz–Morrey spaces. Our results encompass Lebesgue and generalized Morrey spaces as special cases. In addition, we characterize the boundedness of composition operators on weak Orlicz–Morrey spaces, which include the Orlicz ...

Nonparametric Control Koopman Operators [PDF]

IEEE Transactions on Automatic Control
This paper presents a novel Koopman composition operator representation framework for control systems in reproducing kernel Hilbert spaces (RKHSs) that is free of explicit dictionary or input parametrizations. By establishing fundamental equivalences between different model representations, we are able to close the gap of control system operator ...
