WebThis article presents a new approach for target identification, in which we fuse scattering data from multiple target-sensor orientations. The multiaspect data is processed via hidden Markov model (HMM) classifiers, buttressed by physics-based feature extraction. This approach explicitly accounts for the fact that the target-sensor orientation is generally … Web1 de jul. de 2024 · In this paper, a novel approach is introduced for integrating multiple feature selection criteria by using hidden Markov model (HMM). For this purpose, five feature selection ranking methods including Bhattacharyya distance, entropy, receiver operating characteristic curve, t-test, and Wilcoxon are used in the proposed topology of …
Web1 de jan. de 2013 · Each time a die is to be chosen, we assume that with probability α, Die A is chosen, and with probability (1 − α ), Die B is chosen. This process is hidden as we don’t know which die is chosen. The value of α is to be determined. The chosen die is then thrown and the number of dots (this is observable) obtained is recorded.
