modeling loss data by phase-type distribution
بیمه گران همیشه بابت خسارات بیمه نامه های تحت پوشش خود نگران بوده و روش هایی را جستجو می کنند که بتوانند داده های خسارات گذشته را با هدف اتخاذ یک تصمیم بهینه مدل بندی نمایند. در این پژوهش توزیع های فیزتایپ در مدل بندی داده های خسارات معرفی شده که شامل استنباط آماری مربوطه و استفاده از الگوریتم em در برآورد پارامترهای توزیع است. در پایان امکان استفاده از این توزیع در مدل بندی داده های گروه بندی ...
Near-perfect Token Distribution
Suppose that n tokens are arbitrarily placed on the n nodes of a graph. At each parallel step one token may be moved from each node to an adjacent node. An algorithm for the near-perfect token distribution problem redistributes the tokens in a minimum number of steps, so that, at the end, no more than O(l) tokens reside at each node. (In perfect distribution, at the end, exactly one token resid...
متن کاملTransition-Optimal Token Distribution
There is given a graph, that models a communication network of a multi-processor system, and there are tokens (jobs) allocated to nodes of the graph. The task is to distribute the tokens evenly, subject to the constraint that they may be moved only along the edges of the graph. The cost of a distribution strategy is measured as the total number of operations of moving a token along an edge. An ...
متن کاملStrongly Adaptive Token Distribution 1
The token distribution (TD) problem, an abstract static variant of load balancing, is defined as follows: let M be a (parallel processor) network with setP of processors. Initially, each processor P ∈ P has a certain amount l(P) of tokens. The goal of a TD algorithm, run on M , is to distribute the tokens evenly among the processors. In this paper we introduce the notion of strongly adaptive TD...
متن کاملToken Identity Vs. Type Identity
Idsardi and Raimy 2000 (I&R) propose that the representations posited by a learner are constrained by economy considerations. If a child hears a string like the Temiar continuative [sglOg], two possibilities are available while building the underlying representation of the string. Either the two segments [g] perceived in the string correspond to different tokens of the same type, or they corres...
