analysis of ruin probability for insurance companies using markov chain
در این پایان نامه نشان داده ایم که چگونه می توان مدل ریسک بیمه ای اسپیرر اندرسون را به کمک زنجیره های مارکوف تعریف کرد. سپس به کمک روش های آنالیز ماتریسی احتمال برشکستگی ، میزان مازاد در هنگام برشکستگی و میزان کسری بودجه در زمان وقوع برشکستگی را محاسبه کرده ایم. هدف ما در این پایان نامه بسیار محاسباتی و کاربردی تر از روش های است که در گذشته برای محاسبه این احتمال ارائه شده است. در ابتدا ما نشا...
15 صفحه اولHidden Markov Models and the Viterbi algorithm
is understood to have N hidden Markov states labelled by i (1 ≤ i ≤ N), and M possible observables for each state, labelled by a (1 ≤ a ≤ M). The state transition probabilies are pij = p(qt+1 = j | qt = i), 1 ≤ i, j ≤ N (where qt is the hidden state at time t), the emission probability for the observable a from state i is ei(a) = p(Ot = a | qt = i) (where Ot is the observation at time t), and t...
متن کاملIntrusion Detection Using Evolutionary Hidden Markov Model
Intrusion detection systems are responsible for diagnosing and detecting any unauthorized use of the system, exploitation or destruction, which is able to prevent cyber-attacks using the network package analysis. one of the major challenges in the use of these tools is lack of educational patterns of attacks on the part of the engine analysis; engine failure that caused the complete training, ...
متن کاملDNA Sequence Analysis using Hidden Markov Model and Genetic Algorithm
We have developed a new method for the analysis of DNA sequences. The method consists of the Hidden Markov Model (HMM) [1] and Genetic Algorithm (GA) [2], and can identify conserved patterns, can estimate the distances between the patterns and can classify the sequences. We have applied the developed method to the extraction of conserved patterns in the vicinity of the 5' end of yeast intron DN...
متن کاملAdjusted Viterbi training for hidden Markov models
We consider estimation of the emission parameters in hidden Markov models. Commonly, one uses the EM algorithm for this purpose. However, our primary motivation is the Philips speech recognition system wherein the EM algorithm is replaced by the Viterbi training algorithm. Viterbi training is faster and computationally less involved than EM, but it is also biased and need not even be consistent...
