Personalized prediction of the risk symptomatic intracerebral hemorrhage (sICH) after stroke thrombolysis is clinically useful. Machine-learning-based modeling may provide personalized sICH thrombolysis.We identified 2578 thrombolysis-treated ischemic patients between January 2013 and December 2016 from a multicenter database, where 70% were used to train models remaining 30% as nominal test sets. Another 136 consecutive tissue plasminogen-activated-treated 2017 our institute enrolled...
In this article, we focus on the stochastic generalized Nash equilibrium problem (SGNEP) which is an important and widely used model in many different fields. model, subject to certain global resource constraints, a set of self-interested players aims optimize their local objectives that depend own decisions others are influenced by some random factors. We propose distributed seeking algorithm partial-decision information setting based Douglas–Rachford operator splitting scheme, relaxes...
The aim of this paper is to find the distributed solution generalized Nash equilibrium problem (GNEP) for a group players that can communicate with each other over connected communication network. Each player tries minimize local objective function its own may depend on players' decisions, and collectively all decisions are subject some globally shared resource constraints. After reformulating optimization problems, we introduce notion network Lagrangian recast GNEP as zero finding properly...
A variety of practical problems can be modeled by the decision-making process in multi-player games where a group self-interested players aim at optimizing their own local objectives, while objectives depend on actions taken others. The gradient information each player, essential implementing algorithms for finding game solutions, is all too often unavailable. In this paper, we focus designing solution using bandit feedback, i.e., only available feedback player's disposal realized objective...

Non-cooperative games serve as a powerful frame-work for capturing the interactions among self-interested players and have broad applicability in modeling wide range of practical scenarios, ranging from power management to drug delivery. Although most existing solution algorithms assume availability first-order information or full knowledge objectives others' action profiles, there are situations where only accessible at players' disposal is realized objective function values. In this paper,...
We explore a class of stochastic multiplayer games where each player in the game aims to optimize its objective under uncertainty and adheres some expectation constraints. The study employs an offline learning paradigm, leveraging pre-existing dataset containing auxiliary features. While prior research deterministic primarily explored vector-valued decisions, this work departs by considering function-valued decisions that incorporate features as input. leverage law large deviations degree...

A distributed seeking algorithm is proposed based Douglas-Rachford operator splitting scheme, which only requires communications among neighbors. The scheme significantly relaxes assumptions co-coercivity contractiveness in...

In stochastic Nash equilibrium problems (SNEPs), it is natural for players to be uncertain about their complex environments and have multi-dimensional unknown parameters in models. Among various SNEPs, this paper focuses on locally coupled network games where the objective of each rational player subject aggregate influence its neighbors.
