Three criteria are used for this weight reestimation: (i) maximum Likelihood Estimation (MLE), (ii) discriminative training by Frame Discrimination (FD), (iii) fast Discriminative Weighting (FDW) which relies on a fast approximation of FD. .
As this is computationally expensive, and we were more interested in a fast approximation, we tried to find a faster alternative that works in a similar direction.
For smooth surfaces, a fast approximation algorithm is developed to calculate the curvature of individual subregions.
For this work, a fast approximation of the bilateral filter [25] has been used.
We anticipate that SIMPLE will be calibrated to other ice sheet models and can provide a fast approximation (emulator) for such models in studies that require many model evaluations.
The other relies on a fast approximation procedure for calculating Poisson-binomial P-values, which we call bi-binomial approximation (BBA) or bi-binomial distribution (BBD).
Our second task is to provide a fast approximation algorithm for Consensus.
However, even with these differences, the results were very surprising because of other research [ 36] and considering the -s F option is a fast approximation of the SW algorithm (see methods for details).
Dynamic programming algorithms, or a fast approximation, have been successfully applied to biological sequence comparison for decades, and this class of algorithms comprises the heart of many well-known sequence alignment programs (Batzoglou, 2005).
Therefore, we propose a fast approximation of P-values based on a bi-binomial distribution.
To this end, here we propose FC, which is a fast approximation of Consensus.
