dc.description.abstractThe present work aims to classify the thought of the five Spanish vowels measured by electroencephalograms (EEG) of 21 electrodes around the Broca's area of the brain of 23 individuals. This was addressed by the framework of spatial functional data, considering each EEG a continuous curve in L2 and performing functional kriging, several images were constructed to apply classification techniques of machine and deep learning. Finally, both classification routines on average achieve more than 91\% precision for each individual, considering that each individual should have its own classification mechanism.

Para esto se empleó el marco de los datos espaciales funcionales, considerando cada medición EEG una curva continua en L2 y realizando kriging funcional, se construyeron varias imágenes para aplicar técnicas de clasificación de aprendizaje de máquina y profundo. Finalmente, ambas rutinas de clasificación en promedio lograron una precisión de más del 91% para cada individuo, hay que tener en cuenta que cada individuo debe contar con su propio mecanismo de clasificación.spa
