... is the WER at the iteration with the best objective function value in the interval (x-20,x]. the CRF algorithm. In the first two trials, the training set consists of the pruned lattices, and the ... shows these times in hours. Be- cause of the frequent update of the weights in the model, the perceptron algorithm is more expensive than the CRF algorithm for a si...
