Brazilian Sign Language Recognition

Sign language is a way of communication with these people and among themselves, characterised by visual-gestural communication. Likely to oral languages, sign languages are unique to each culture, with their own grammatical structures. Its structure unit, called “sign”, comprises hand configuration, location and movements, palm orientation, face and torso movement, which are manual and non-manual parameters.

Integrating Q-Learning in Adaptive Large Neighborhood Search Metaheuristic for the Parallel Machine Scheduling

An important scheduling problem is dealt in this project. The unrelated parallel machine scheduling with the objective to minimize the makespan is addressed. This problem has a set of non-preemptive jobs and a set of machines with the following characteristics: i) Each job is allocated to only one machine; ii) There is a processing time to complete each job in a machine; iii) There is a setup time that depends on the sequence of the allocation of the jobs in the machines. The objectives involve allocating all jobs in the machines, minimizing the makespan (or the maximum completion time of the scheduling).

Data Visualization in Many Objective Optimization Problems (MaOPs)

Data Visualization in high-dimensional spaces is a great challenge and an important tool for decision-making. The method of Aggregation Trees was an important step in visualization in MaOPs, allowing a greater understanding of the problem. This method is based on the sequential aggregation of objectives, which is visually represented into a tree, based on a measure of conflict between pairs of (groups of) objectives. The method allows the visualization of a hierarchy for aggregation of the objectives, with possibility to create new constraints for the problem or reduce the number of objectives in a further analysis.
