Optimal Dorfman Group Testing for Symmetric Distributions
SIAM Journal on Mathematics of Data ScienceWe study Dorfman's classical group testing protocol in a novel setting where individual specimen statuses are modeled as exchangeable random variables. We are motivated by infectious disease screening. In that case, specimens which arrive together for testing often originate from the same community and so their statuses may exhibit positive correlation.

Application of soft computing algorithms for hybrid modular multilevel inverters
Measurement: SensorsThis study utilized Harris Hawk optimization to analyze the harmonic distortions of a symmetric capacitor based multilevel converter. The proposed multilevel converter uses identical and symmetric DC sources in its input.

Separability of diagonal symmetric states: a quadratic conic optimization problem [PDF]
Quantum, 2018 We study the separability problem in mixtures of Dicke states i.e., the separability of the so-called Diagonal Symmetric (DS) states. First, we show that separability in the case of DS in $C^d\otimes C^d$ (symmetric qudits) can be reformulated as a ...

Symmetric Behavior Regularized Policy Optimization
Behavior Regularized Policy Optimization (BRPO) leverages asymmetric (divergence) regularization to mitigate the distribution shift in offline Reinforcement Learning. This paper is the first to study the open question of symmetric regularization. We show that symmetric regularization does not permit an analytic optimal policy $π^*$, posing a challenge ...
