This requires the calculation of the second-order derivatives, for which several approximative techniques have been proposed in the context of recurrent neural networks. These calculations are expensive, but can accelerate convergence especially near an optimum where the error surface can be reasonably ...

This program calculates the word error rate of hypothesis in ASR and print the aligned result. - GitHub - zszyellow/WER-in-python: This program calculates the word error rate of hypothesis in ASR and print the aligned result.
Once the matrix is determined, a confusability calculation may be performed. Different methods are used to determine synthetic likelihoods. The confusability may be normalized and smoothed and methods are disclosed that increase the speed of performing the matrix inversion and the confusability ...
While this appears to be a minor change, it can have a significant impact on the percentage error, depending on the variables in the denominator of the equation. The same formula applies for correctable codeword errors. While a correctable error rate of over 5% seems high, it is important ...
To code the students’ production, we employed tree diagrams representing the generated equations or the arithmetic calculation (Figs. 1 and 2, respectively). We started from the lower level, placing there either known quantities and letters assigned to a quantity (equation task) or the concrete ...
Whereas the gradient descent computes parameter updates after sum- ming over all training samples as shown in Equation (7), the stochastic approximation method updates parameters incrementally, following the calculation of the error for each individual training sample, as shown in Equation (8). G(...
(Fig.1b). In prediction error calculation, there is no need for a retention mechanism for the prediction signal until the next word arrives, since the persistent predictive signal of Purkinje cells ensures that the circuit output persists. Also, a series of studies indicate that the cerebellum ...
The calculation of TF-IDF is: (1.1)Wi,j=Wi,jtf×Wi,jidf, where the TF (term frequency) [28] reveals the importance of this word in the target image and is obtained by calculating the occurrence frequency of this word in the target image as: (1.2)Wi,jtf=njinj, where nji is ...
