Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Geometric Singular Perturbation Theory and Traveling Pulses with Monotone Tails in a Diffusive Rosenzweig MacArthur Model
扩散 罗森茨威格麦克阿瑟模型 几何奇异摄动理论 单调尾巴行进脉冲
2023/5/5
In this talk, we first briefly review history of the geometric singular perturbation theory, then talk about the traveling pulses for a diffusive Rosenzweig MacArthur model. We show the existence of t...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：First-order methods for convex optimization and monotone inclusions under local Lipschitz conditions
局部利普希茨条件 凸优化 单调夹杂物 一阶方法
2023/5/6
In this talk, we first consider convex optimization whose smooth components have a locally Lipschitz continuous gradient and propose a first-order method for finding an epsilon-KKT solution. We then c...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Maximizing Approximately Non-k-Submodular Monotone Set Function with Matroid Constraint
最大化 矩阵约束 近似非k子模 单调集函数
2023/5/12
Utilizing approximation algorithm, there has been a large quantity of work on optimization for submodular functions since the 1970s. As a variant, $k$-submodular function appears in many fields to mat...
Error-Detecting in Monotone Span Programs with Application to Communication Efficient Multi-Party Computation
MPC cryptographic protocols
2018/5/22
Recent improvements in the state-of-the-art of MPC for non-full-threshold access structures introduced the idea of using a collision-resistant hash functions and redundancy in the secret-sharing schem...
Monotone Batch NP-Delegation with Applications to Access Control
delegation witness indistinguishability access control
2018/5/2
Consider an access policy for some resource which only allows access to users of the system who own a certain set of attributes. Specifically, we consider the case where such an access structure is de...
Proof of Knowledge on Monotone Predicates and its Application to Attribute-Based Identifications and Signatures
secondary-key public-key cryptography
2016/5/24
We propose a concrete procedure of a \Sgm-protocol to prove knowledge that satisfies a monotone predicate. Inspired by the high-level proposal by Cramer, Damg\r{a}rd and Schoenmakers at CRYPTO '94, we...
Non-Interactive Verifiable Secret Sharing For Monotone Circuits
cryptographic protocols computational secret-sharing
2016/2/24
We propose a computationally secure and non-interactive verifiable secret sharing scheme
that can be efficiently constructed from any monotone Boolean circuit. By non-interactive we mean that
the de...
On the nonlinearity of monotone Boolean functions
Boolean functions monotone functions Walsh–Hadamard spectrum
2016/2/23
We first prove the truthfulness of a conjecture on the nonlinearity of
monotone Boolean functions in even dimension, proposed in the recent paper “Cryptographic
properties of monotone Boolean functi...
Bounds for the Sum of Dependent Risks and Worst Value-at-Risk with Monotone Marginal Densities
Complete mixability Monotone density Sum of dependent risks Value-at- Risk
2016/1/25
In quantitative risk management, it is important and challenging to find sharp bounds for the distribution of the sum of dependent risks with given marginal distributions, but an unspecified dependenc...

In quantitative risk management, it is important and challenging to find sharp bounds for the distribution of the sum of dependent risks with given marginal distributions, but an unspecified dependenc...
POINTWISE A POSTERIORI ERROR ESTIMATES FOR MONOTONE SEMI-LINEAR EQUATIONS
residual maximum norm
2015/12/11
We derive upper and lower a posteriori estimates for the maximum norm error in nite element solutions of monotone semi-linear equations.
The estimates hold for Lagrange elements of any xed order, n...
We consider the least angle regression and forward stagewise algorithms for solving penalized least squares regression problems. In Efron,Hastie, Johnstone & Tibshirani (2004) it is proved that the le...
We also
study a condition under which the coefficient paths of the lasso are monotone, and hence the different algorithms coincide. Finally, we compare the
lasso and forward stagewise pro...
The Value of Information in Monotone Decision Problems
Monotone Decision Problems Information
2015/7/21
We analyze the information
preferences and information demand of such decision-makers, based on properties of their
payoff functions. We restrict attention to “monotone decision problems,” whe...
