mortality forecasting based on lee-carter model
over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...
15 صفحه اولWorkload Hidden Markov Model for Anomaly Detection
We present an approach to anomaly detection based on the construction of a Hidden Markov Model trained on processor workload data. Based on processor load measurements, a HMM is constructed as a model of the system normal behavior. Any observed sequence of processor load measurements that is unlikely generated by the HMM is then considered as an anomaly. We test our approach taking real data of...
متن کاملHidden semi-Markov model for anomaly detection
In this paper, hidden semi-Markov model (HSMM) is introduced into intrusion detection. Hidden Markov model (HMM) has been applied in intrusion detection systems several years, but it has a major weakness: the inherent duration probability density of a state in HMM is exponential, which may be inappropriate for the modeling of audit data of computer systems. We can handle this problem well by de...

متن کاملAnomaly Detection based on Probabilistic Properties of Hidden Markov Models
Due to increasing use of the Internet, there is a trend of increasing attacks over networks. Therefore, we have need of study for network anomaly detection and measurement scheme to network state. In this research, we propose a scheme for anomaly detection based on the traffic behavior of Hidden Markov Models. The proposed scheme detects anomalies in traffic using a time series. We decide wheth...
