It can map the original features in any number of dimensions and had good resilience to noise. This kernel function has been used successfully in previous fire detection research [38]. The sigmoid kernel function is derived from neural networks and is often used as a threshold function for ...

Abstract: In this paper, a GA-BP sound quality prediction model is established and a sound quality contribution factor (SQCF) is introduced for more intuitively reflecting the contribution of structural noise transmission path to annoyance and the influence of masking effect on sound quality. Two-...
effect ash according to furtive rules. Piles of faux cinders accumulate on the floor and sofas as if in the aftermath of some unidentified cataclysm. In fact, the speed and quantity of the ash falls, and thus the sizes and shapes of the piles, each visibly manifest the noise level ...
