Due to the nature of the geological and mining activities, different input parameters in the grade estimation and mineral resource evaluation are always tainted with uncertainties. It is possible to investigate the uncertainties related to the measurements and parameters of the variogram model using the fuzzy kriging method instead of the kriging method. The fuzzy kriging theory has already bee...

Power retail companies in the electricity market make profits through buying and selling power energy wholesale markets, respectively. Traditionally, they are assumed to bid with same objective, i.e., maximize profit. This paper proposes a multiagent reinforcement learning (MRL)-based model simulate diverse bidding decision-making concerning various operation objectives profit-sharing modes of ...

Recommender systems have been successfully applied to alleviate the problem of information overload and assist users’ decision makings. Multi-stakeholder recommender produce item recommendations end user by considering perspective multiple stakeholders. Existing research on multi-stakeholder relies offline evaluations only, online studies are still under investigation. This paper made first att...

Multilayer perceptrons with hard-limiting (signum) activation functions can form complex decision regions. It is well known that a three-layer perceptron (two hidden layers) can form arbitrary disjoint decision regions and a two-layer perceptron (one hidden layer) can form single convex decision regions. This paper further proves that single hidden layer feedforward neural networks (SLFN's) wit...

Blockchain eliminates the need for trusted third-party intermediaries in business by enabling decentralised architecture design software applications. However, vulnerabilities on-chain autonomous decision-makings and cumbersome off-chain coordination lead to serious concerns about blockchain's ability behave a trustworthy efficient way. governance has received considerable attention support dec...

The result by Dvoretzky, Wald, and Wolfowitz on the sufficiency of nonrandomized decision rules for statistical decision problems with nonatomic state distributions holds for arbitrary Borel decision sets and for arbitrary measurable loss functions.
