书籍简介
在这项开创性的工作中，计算机科学家Leslie G. Valiant详细介绍了研究人类大脑错综复杂的工作的一种有希望的新计算方法。作者重点关注大脑在推理过程中快速访问大量累积信息的神秘能力。作者问道，鉴于大脑中有限的神经元数量、有限的通信速度和有限的互连性所带来的极端限制，这种壮举是如何实现的。瓦里安提出了一个 "神经元模型"，作为探索这些问题的载体。
在接受麦库洛赫和皮茨现在的经典理论的同时，神经元模型还容纳了神经元中的状态信息、更灵活的计时机制、关于互连性的各种假设，以及不同区域执行不同功能的可能性。
该模型是可编程的，因此可以描述和评估广泛的算法理论，它提供了一种具体的计算语言和一个统一的框架，在这个框架中，不同的认知现象——如记忆、学习和推理，可以被系统地和同步地分析。本卷包括一个新的序言，强调了自该模型刚出版以来，神经潮汐模型与神经生物学的发现之间的一些显著的一致点。实验产生了强有力的证据，证明了该理论关于大脑皮层中存在强突触的预言以及关于突触的存在以及神经元内部和之间使用准确的计时机制。该理论还提供了一个定量的解释，说明随机放置的神经元如何能够被用作一般目的的学习和记忆的资源，在大脑皮层中发现的神经发生。
《思维回路》不需要专业知识，为计算机科学、神经生物学、神经科学、人工智能和认知科学的学生和研究人员提供了一种令人兴奋的脑科学新方法。
In this groundbreaking work, computer scientist Leslie G. Valiant details a promising new computational approach to studying the intricate workings of the human brain. Focusing on the brain's enigmatic ability to access a massive store of accumulated information very quickly during reasoning processes, the author asks how such feats are possible given the extreme constraints imposed by the brain's finite number of neurons, their limited speed of communication, and their restricted interconnectivity. Valiant proposes a "neuroidal model" that serves as a vehicle to explore these fascinating questions.
While embracing the now classic theories of McCulloch and Pitts, the neuroidal model also accommodates state information in the neurons, more flexible timing mechanisms, a variety of assumptions about interconnectivity, and the possibility that different areas perform different functions.
Programmable so that a wide range of algorithmic theories can be described and evaluated, the model provides a concrete computational language and a unified framework in which diverse cognitive phenomena--such as memory, learning, and reasoning--can be systematically and concurrently analyzed. Included in this volume is a new preface that highlights some remarkable points of agreement between the neuroidal model and findings in neurobiology made since that model's original publication. Experiments have produced strong evidence for the theory's predictions about the existence of strong synapses in cortex and about the use of precise timing mechanisms within and between neurons. The theory also provides a quantitative explanation of how randomly placed neurons can be harnessed as resources for general purpose learning and memory--and is therefore synergistic with the striking recent discovery of neurogenesis in cortex.
Requiring no specialized knowledge, Circuits of the Mind, masterfully offers an exciting new approach to brain science for students and researchers in computer science, neurobiology, neuroscience, artificial intelligence, and cognitive science.
