摘要:

受生物学和神经科学领域发现的启发,人工智能领域在过去几十年中取得了重大进展。这项工作的想法是受到人类大脑皮层区域从传入和横向/内部连接的自组织过程的启发。在这项工作中,我们开发了一个原始的大脑启发的神经模型,将自组织映射(SOM)和Hebbian学习关联在可重入SOM(ReSOM)模型中。该框架适用于多模态分类问题。与现有的基于后标记的无监督学习方法相比,该模型增强了最先进的结果。这项工作还通过仿真结果和在基于FPGA的专用平台SCALP(可自配置3D蜂窝自适应平台)上的硬件执行来演示该模型的分布式和可扩展性。SCALP板可以以模块化的方式互连,以支持神经模型的结构。这种统一的软件和硬件方法使得处理能够被缩放,并且允许来自若干模态的信息被动态地合并。硬件板上的部署提供了在多个设备上并行执行的性能结果,每个板之间通过专用串行链路进行通信。由ReSOM模型和SCALP硬件平台组成的拟议统一架构显示,由于多模态关联,准确性显著提高,并且与集中式GPU实现相比,延迟和功耗之间具有良好的权衡。

英文摘要:

The field of artificial intelligence has significantly advanced over the past decades, inspired by discoveries from the fields of biology and neuroscience. The idea of this work is inspired by the process of self-organization of cortical areas in the human brain from both afferent and lateral/internal connections. In this work, we develop an original brain-inspired neural model associating Self-Organizing Maps (SOM) and Hebbian learning in the Reentrant SOM (ReSOM) model. The framework is applied to multimodal classification problems. Compared to existing methods based on unsupervised learning with post-labeling, the model enhances the state-of-the-art results. This work also demonstrates the distributed and scalable nature of the model through both simulation results and hardware execution on a dedicated FPGA-based platform named SCALP (Self-configurable 3D Cellular Adaptive Platform). SCALP boards can be interconnected in a modular way to support the structure of the neural model. Such a unified software and hardware approach enables the processing to be scaled and allows information from several modalities to be merged dynamically. The deployment on hardware boards provides performance results of parallel execution on several devices, with the communication between each board through dedicated serial links. The proposed unified architecture, composed of the ReSOM model and the SCALP hardware platform, demonstrates a significant increase in accuracy thanks to multimodal association, and a good trade-off between latency and power consumption compared to a centralized GPU implementation.
