The effectiveness, robustness, and flexibility of memory and learning constitute the very essence of human natural intelligence, cognition, and consciousness. However, currently accepted views on these subjects have, to date, been put forth without any basis on a true physical theory of how the brain communicates internally via its electrical signals. This lack of a solid theoretical framework has implications not only for our understanding of how the brain works, but also for wide range of computational models developed from the standard orthodox view of brain neuronal organization and brain network derived functioning based on the Hodgkin-Huxley ad-hoc circuit analogies that have produced a multitude of Artificial, Recurrent, Convolution, Spiking, etc., Neural Networks (ARCSe NNs) that have in turn led to the standard algorithms that form the basis of artificial intelligence (AI) and machine learning (ML) methods. Our hypothesis, based upon our recently developed physical model of weakly evanescent brain wave propagation (WETCOW) is that, contrary to the current orthodox model that brain neurons just integrate and fire under accompaniment of slow leaking, they can instead perform much more sophisticated tasks of efficient coherent synchronization/desynchronization guided by the collective influence of propagating nonlinear near critical brain waves, the waves that currently assumed to be nothing but inconsequential subthreshold noise. In this paper we highlight the learning and memory capabilities of our WETCOW framework and then apply it to the specific application of AI/ML and Neural Networks. We demonstrate that the learning inspired by these critically synchronized brain waves is shallow, yet its timing and accuracy outperforms deep ARCSe counterparts on standard test datasets. These results have implications for both our understanding of brain function and for the wide range of AI/ML applications.
记忆和学习的有效性、稳健性和灵活性构成了人类自然智能、认知和意识的本质。然而,迄今为止,对于这些主题的现有观点都是在没有任何关于大脑如何通过电信号进行内部通信的真实物理理论基础上提出的。这种缺乏坚实理论框架的情况不仅对我们理解大脑如何工作产生了影响,而且对广泛的计算模型也产生了影响,这些模型是从基于 Hodgkin-Huxley 临时电路类比的大脑神经元组织和大脑网络功能的标准正统观点发展而来的,这些类比产生了许多人工、递归、卷积、尖峰等神经网络 (ARCSeNNs),进而导致了作为人工智能 (AI) 和机器学习 (ML) 方法基础的标准算法。我们的假设是基于我们最近开发的弱瞬变脑波传播物理模型 (WETCOW),与当前的正统模型相反,即大脑神经元只是在缓慢泄漏的伴随下进行整合和发射,它们可以执行更复杂的任务,通过传播的非线性近临界脑波的集体影响进行有效的相干同步/去同步,这些波目前被认为只是无关紧要的亚阈值噪声。在本文中,我们强调了我们的 WETCOW 框架的学习和记忆能力,然后将其应用于 AI/ML 和神经网络的特定应用。我们证明,受这些临界同步脑波启发的学习虽然较浅,但在标准测试数据集上,其定时和准确性优于深度 ARCSe 对应物。这些结果对我们理解大脑功能和广泛的 AI/ML 应用都具有重要意义。
