The threshold EM algorithm for parameter learning in bayesian network with incomplete data
Fradj Ben Lamine, Karim Kalti, Mohamed Ali Mahjoub
Bayesian networks (BN) are used in a big range of applications but they have one issue concerning parameter learning. In real application, training data are always incomplete or so…
Characterization of Dynamic Bayesian Network
Nabil ghanmy, Mohamed Ali Mahjoub, Najoua Essoukri Ben Amara
In this report, we will be interested at Dynamic Bayesian Network (DBNs) as a model that tries to incorporate temporal dimension with uncertainty. We start with basics of DBN where…
