Abstract

É, PORTANTO, UM OBJECTIVO DA PRESENTE INVENÇÃO UMA UNIDADE DE ATENÇÃO MULTI-CONVOLUCIONAL BI-DIMENSIONAL - 2D - A SER APLICADA NO DESEMPENHO DE ANÁLISE DE DADOS TRI-DIMENSIONAL - 3D - MTS, DE DADOS DE ENTRADA (1) COM PROPRIEDADES CÍCLICAS, UTILIZANDO UMA ARQUITECTURA RNN. ESTA UNIDADE É CAPAZ DE CONSTRUIR UM VECTOR DE ATENÇÃO INDEPENDENTE Α POR CADA VARIÁVEL DO MTS UTILIZANDO OPERAÇÕES CONVOLUCIONAIS 2D PARA CAPTURAR A IMPORTÂNCIA DE UMA ETAPA TEMPORAL DENTRO DOS SEGMENTOS CIRCUNDANTES E DA ÁREA DE ETAPAS TEMPORAIS. PARA ESSE PROPÓSITO, A UNIDADE DE ATENÇÃO BIDIMENSIONAL É COMPOSTA POR UM BLOCO DE DIVISÃO (2), UM BLOCO DE ATENÇÃO (3), UM BLOCO DE CONCATENAÇÃO (4) E UM BLOCO DE ESCALONAMENTO (5).IT IS, THEREFORE, AN OBJECTIVE OF THE PRESENT INVENTION A TWO-DIMENSIONAL - 2D - MULTI-CONVOLUTIONAL ATTENTION UNIT TO BE APPLIED IN THE PERFORMANCE OF THREE-DIMENSIONAL - 3D - MTS DATA ANALYSIS, OF INPUT DATA (1) WITH CYCLIC PROPERTIES, USING AN RNN ARCHITECTURE. THIS UNIT IS CAPABLE OF CONSTRUCTING AN INDEPENDENT ATTENTION VECTOR Α FOR EACH MTS VARIABLE USING CONVOLUTIONAL 2D OPERATIONS TO CAPTURE THE IMPORTANCE OF A TEMPORAL STEP WITHIN THE SURROUNDING SEGMENTS AND THE TEMPORAL STEPS AREA. FOR THIS PURPOSE, THE TWO-DIMENSIONAL ATTENTION UNIT IS COMPOSED OF A SPLITTING BLOCK (2), A ATTENTION BLOCK (3), A CONCATENATION BLOCK (4) AND A STEERING BLOCK (5).
