... (13) Obtaining a closed form expression for x ∗ from (13) can be difficult. A feasible approach is to perform the reconstruction process using a constant propagation value estimate, v f , for the whole scan ... Entropy values for the interval [1 ×10 8 m/s, 3 × 10 8 m/s]. (d) Dataset reconstructed using v ∗ . Table 3: Estimation errors and exe cution times of the proposed method and the...

... 1 words. We can follow the same EM procedure for parameter estimation in the n-gram-PLSA model where w i is replaced by h i in all formulae. In the re -estimation formulae, we have n(d k , h i , w j ) ... that model. One cannot derive the re- estimation formulae via the standard EM procedure based on Nie et al.’s model. In this paper, we propose an EM procedure for re-estimating th...
