younos bin abdorrahmān, is one of the prominent companions of imams. in addition to many validating (ta'adil) narratoins, the invalidating (jarh) ones were also reported in the sources about him. regarding the conflicts between these two groups of narrations, various solutions were proposed by rijāli scholars; such as: - some of the invalidating narrations about him are fabricated;- many o...

Consensus formation among n experts is modeled as a positive discrete dynamical system in n dimensions. The well–known linear but non–autonomous model is extended to a nonlinear one admitting also various kinds of averaging beside the weighted arithmetic mean. For this model a sufficient condition for reaching a consensus is presented. As a special case consensus formation under bounded confide...

For a confidence interval (L(X),U(X)) of a parameter θ in one-parameter discrete distributions, the coverage probability is a variable function of θ . The confidence coefficient is the infimum of the coverage probabilities, infθ Pθ (θ ∈ (L(X),U(X))). Since we do not know which point in the parameter space the infimum coverage probability occurs at, the exact confidence coefficients are unknown....

We derive sublinear regret bounds for undiscounted reinforcement learning in continuous state space. The proposed algorithm combines state aggregation with the use of upper confidence bounds for implementing optimism in the face of uncertainty. Beside the existence of an optimal policy which satisfies the Poisson equation, the only assumptions made are Hölder continuity of rewards and transitio...
