Combinations and Mixtures of Optimal Policies in Unichain Markov Decision Processes are Optimal [PDF]
arXiv, 2005 We show that combinations of optimal (stationary) policies in unichain Markov decision processes are optimal. That is, let M be a unichain Markov decision process with state space S, action space A and policies \pi_j^*: S -> A (1\leq j\leq n) with optimal average infinite horizon reward.

Adverse prognosis gene expression patterns in metastatic castration‐resistant prostate cancer
Molecular Oncology, EarlyView.We aggregated a cohort of 1012 mCRPC tissue samples from 769 patients and investigated the association of gene expression‐based pathways with clinical outcomes. Loss of AR signaling, high proliferation, and a glycolytic phenotype were independently prognostic for poor outcomes, and an adverse transcriptional feature score incorporating these pathways ...

Discrete Time Mean-Field Stochastic Linear-Quadratic Optimal Control Problems [PDF]
arXiv, 2013 This paper first presents necessary and sufficient conditions for the solvability of discrete time, mean-field, stochastic linear-quadratic optimal control problems. Then, by introducing several sequences of bounded linear operators, the problem becomes an operator stochastic LQ problem, in which the optimal control is a linear state feedback ...

Molecular Oncology, EarlyView.Chronic TGF‐β exposure drives epithelial HCC cells from a senescent state to a TGF‐β resistant mesenchymal phenotype. This transition is characterized by the loss of Smad3‐mediated signaling, escape from senescence, enhanced invasiveness and metastatic potential, and upregulation of key resistance modulators such as MARK1 and GRM8, ultimately promoting

Securing federated learning: a defense strategy against targeted data poisoning attack
Discover Internet of ThingsEnsuring the security and integrity of Federated Learning (FL) models against adversarial attacks is critical. Among these threats, targeted data poisoning attacks, particularly label flipping, pose a significant challenge by undermining model accuracy ...

Continuity of the Value Function in Sparse Optimal Control [PDF]
arXiv, 2014 We prove the continuity of the value function of the sparse optimal control problem. The sparse optimal control is a control whose support is minimum among all admissible controls. Under the normality assumption, it is known that a sparse optimal control is given by L^1 optimal control.
