Linear threshold

Nettet2.1 Linear threshold models We first describe the linear threshold model, introduced by Kempe et al. [9]. In this model, the edge weights (b ij) denote the influence that node ihas on node j. The chance that a node is infected depends on two quantities: the set of infected neighbors at a particular time instant and a random Nettet16. okt. 2024 · Given an initial estimate of all model parameters, we alternatively. 1. update the threshold parameter e and the coefficients β ’s and γ that are associated with thresholded covariate, conditional on the rest of the model parameters estimates, \hat {\alpha }, 2. update all coefficients, α, β ’s and γ, conditional on the estimated ...

Presumably, this is because more of the driving is stop and go. New buses switch their engines off when stopped. Rather interestingly, in region 1 old buses pollute 0.07−0.06 = 0.01 more than new buses.
