Mobile interfaces need to allow the user and system to adapt their choice of communication modes according to user preferences, the task at hand, and the physical and social environment. We describe a multimodal application architecture which combines finite-state multimodal language processing, a speech-act based multimodal dialogue manager, dynamic multimodal output generation, and user-tailo...

Emotion recognition is a strategy for social robots used to implement better Human-Robot Interaction and model their behaviour. Since human emotions can be expressed in different ways (e.g., face, gesture, voice), multimodal approaches are useful support the process. However, although there exist studies dealing with emotion robots, they still present limitations fusion process, dropping perfor...

We describe a hybrid meta-heuristic algorithm for combinatorial optimization problems with a specific reference to the travelling salesman problem (TSP). The method is a combination of a genetic algorithm (GA) and greedy randomized adaptive search procedure (GRASP). A new adaptive fuzzy a greedy search operator is developed for this hybrid method. Computational experiments using a wide range of...

This paper presents simple analytical models of genetic algorithms which are commonly used in multimodal function optimization. The methodology for constructing the models is similar throughout the study. The predictive value of each model is veriied by running the corresponding genetic algorithm on various multimodal functions of varying complexity.

Today, in computer science, a computational challenge exists in finding a globally optimized solution from an enormously large search space. Various meta-heuristic methods can be used for finding the solution in a large search space. These methods can be explained as iterative search processes that efficiently perform the exploration and exploitation in the solution space. In this context, thre...

This paper describes application oriented research on architectural building blocks and constraints for adaptive multimodal dialog systems that use VoiceXML as a component technology. The VoiceXML standard is well supported and promises to make the development of speech-enabled applications so easy that everyone with general web programming skills can accomplish it. The paper proposes a softwar...
