基于硅CO_2模型的事件驱动谱时特征提取与分类
Event-driven Spectrotemporal Feature Extraction and Classification using a Silicon Cochlea Model
摘要:
本文提出了一种基于事件的双耳耳蜗系统的现场可编程门阵列(FPGA)的可重构数字实现。它由一对具有快速作用压缩(CAR FAC)的非对称谐振器级联(Cascade of Asymmetric Resonators with Fast Acting Compression)耳蜗模型和泄漏整合和激发(LIF)神经元组成。此外,我们提出了一个事件驱动的SpectroTemporal感受野(STRF)的特征提取使用自适应选择权(FEAST)。在TIDIGTIS基准上进行了测试,并与当前基于事件的听觉信号处理方法和神经网络进行了比较。
英文摘要:
This paper presents a reconfigurable digital implementation of an event-based binaural cochlear system on a Field Programmable Gate Array (FPGA). It consists of a pair of the Cascade of Asymmetric Resonators with Fast Acting Compression (CAR FAC) cochlea models and leaky integrate and fire (LIF) neurons. Additionally, we propose an event-driven SpectroTemporal Receptive Field (STRF) Feature Extraction using Adaptive Selection Thresholds (FEAST). It is tested on the TIDIGTIS benchmark and compared with current event-based auditory signal processing approaches and neural networks.
