Comparing Marginal Fit and Marginal Gap between Sholder Bevel and 135° Finish Line Designs in Posterior Metal Ceramic Restoration Crowns
Background and purpose: One of the major challenges for dentists is providing the patients with a crown of appropriate marginal fit and marginal gap. Preparation of a 135° finish line has some advantages such as technical ease and appropriate finish line record. Nevertheless, few studies investigated this type of finish line. The current study aimed at comparing marginal fit and marginal gap in...
متن کاملLearning unbelievable marginal probabilities
Loopy belief propagation performs approximate inference on graphical models with loops. One might hope to compensate for the approximation by adjusting model parameters. Learning algorithms for this purpose have been explored previously, and the claim has been made that every set of locally consistent marginals can arise from belief propagation run on a graphical model. On the contrary, here we...
متن کاملMarginal Boosting 1
AdaBoost produces a linear combination of weak hypotheses. It has been observed in practice that the generalization error of the algorithm continues to improve even after all examples are classified correctly by the current linear combination, i.e. by a hyperplane in feature space where each weak hypothesis is a dimension. The improvement is attributed to the experimental observation that the d...
متن کاملMixtures of Marginal Models
In this paper, we adapt a mixture model originally developed for regression models with independent data for the more general case of correlated outcome data, which includes longitudinal data as a special case. The estimation is performed by a gener-alisation of the EM algorithm which we call the Expectation-Solution (ES) algorithm. In this ES algorithm the M-step of the EM algorithm is replace...
متن کاملExperimental marginal corneal infiltrates.
Marginal infiltrates arise from a wide variety of causes and according to the recent literature occur most commonly in association with chronic staphylococcal blepharitis. Marginal infiltrates often have a crescent form or coalesce to form a complete ring concentric to the limbus. On the other hand, the well-formed manifestation of an immunological process in the cornea, the so-called immunolog...
