Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：The complexity of computing Markov perfect equilibrium in general-sum stochastic games
一般 随机博弈 马尔可夫完美均衡 计算复杂性
2023/5/12
Similar to the role of Markov decision processes in reinforcement learning, Markov games (also known as stochastic games) form the basis for the study of multi-agent reinforcement learning and sequenc...
Is the whole not greater than the sum of its parts? The case of sarcopenic obesity
muscle institutionalization fat mass sarcopenia
2018/11/14
Sarcopenia is defined as the loss of muscle mass and function with aging, which accelerates after the seventh decade of life and is a harbinger for the onset of disability and institutionalization (1)...

Sum of Parts Scientist Math Environmental Restoration
2017/3/14
The oft-quoted proverb, “Too many cooks spoil the broth,” is apt wisdom for describing challenges facing policy makers, public resource managers, ag producers, industry, residents and other ...
Segmentation of ARX-models using sum-of-norms regularization
Segmentation Regularization ARX-models
2015/8/7
Segmentation of time-varying systems and signals into models whose parameters are piecewise constant in time is an important and well studied problem. It is here formulated as a least-squares problem ...
Maximizing a sum of sigmoids
Sigmoid function convex constraint set mathematics marketing network planning
2015/8/7
The problem of maximizing a sum of sigmoidal functions over a convex constraint set arises in many application areas. This objective captures the idea of decreasing marginal returns to investment, and...

Gauss Sum Combinatorics and Metaplectic Eisenstein Series
Metaplectic Eisenstein Series Gauss Sum Combinatorics
2015/7/6
For metaplectic covers of these groups, the Whittaker models may or may not be
unique. Gelbart and Piatetski-Shapiro considered the representations of the double
cover of SL2 that have unique Whitta...
Tractable fitting with convex polynomials via sum-of-squares
via sum-of-squares Tractable fitting
2015/6/19
We consider the problem of fitting given data with a convex polynomial. A technique to solve this problem using sum of squares polynomials is presented. This technique is extended to enforce convexity...
Analysis of Polynomial Systems with Time Delays via the Sum of Squares Decomposition
Time Delays via Polynomial Systems
2015/6/19
We present a methodology for analyzing robust independent-of-delay and delay-dependent stability of equilibria of systems described by nonlinear Delay Differential Equations by algorithmically constru...
CHIRAL SUM-RULES AND THEIR PHENOMENOLOGY
Vector spectrum function the lepton decay positive negative electron scattering experiment data the spectral function database
2014/12/23
We present an analysis of four sum rules, each based on chiral symmetry and containing the difference ρV(s) − ρA(s) of isovector vector and axialvector spectral functions. Experimental data from...
Calculation of a weak nonleptonic matrix element using “Weinberg” sum rules
Weak matrix element vector and axis vector spectrum function spectral function
2014/12/23
There is a ``toy'' weak matrix element which can be expressed as an integral over the vector and axial vector spectral functions, $\rho_V (s) - \rho_A (s)$. I review our recent evaluation of these spe...
