In all the cases, the co-articulation parameter was set to t c =3, which proved to be the optimal value in the given range.
This combination of number of states, number of mixtures and co-articulation parameter was among the ones that yielded the best results.
For the optimal value of the co-articulation parameter t c =3 set in this article, the system has a time delay of approximately 100 ms. These computational times are suitable for a real-time operation of the system.
In these experiments, the optimal value of the co-articulation parameter was t c = 3, which corresponds to a co-articulation timea of 100 ms. Compared to the previous experiment, where a reduced vocabulary (digits utterances) was employed, the number of states needed in this case increases considerably due to the fact that a larger vocabulary is being represented by the AV-HMM.
The true and estimated visual parameters for the case of full covariance matrices with N = 28 states, M = 5 mixtures and co-articulation parameter t c = 3 are represented in Figure 8, where a good agreement between them can be observed.
Experiments were performed with AV-HMM with full covariance matrices, different number of states and mixtures in the ranges from 8 to 40, and from 2 to 7, respectively, and different values of the co-articulation parameter t c in the range from 0 to 7.
To evaluate the influence of the structure of the covariance matrices on the audio-to-visual conversion algorithm, experiments were performed using AV-HMMs with diagonal and full covariance matrices, different number of states and mixtures in the ranges from 2 to 19, and from 3 to 20, respectively, and different values of the co-articulation parameter t c in the range from 0 to 7.
The long-term objective is not assimilation or adaptation to milieus traditionally closed to women, but rather an articulation of individual parameters and active participation in a nuanced art public".
We expect equal functional scores, greater range of motion, less dislocations, fewer periprosthetic radiolucencies and increased prosthetic survival with the MM articulation (secondary outcome parameters).
As the present study did not include articulation materials as a parameter, we cannot tell whether these uncemented prostheses included cups with UHMWPE liners, or if articulations based on highly crosslinked polyethylene, metal-on-metal, or ceramic-on-ceramic were used.
