The effect of the SOM neural map size and number of BMUs per frame on classification accuracy. A larger neural map can capture more feature variations and generate more discriminative spiking patterns for different sound events. However, the accuracy plateaus once the number of neurons exceeds 121. As shown in the inset, for neural maps of size above 121, increasing the number K of BMUs for each frame enhances system robustness with redundancy and improves classification accuracy.
