在1982年,一篇论文横空出世,仿佛神经网络这匹困兽再次苏醒,也预示着神经网络在AI 领域的崛起,这篇论文叫《Neural networks and physical systems with emergent collective computational abilities》(具有涌现性集体计算能力的神经网络和物理系统),作者是John Hopfield。论文中提到的associative neural network就是后来被人们...
接到诺奖委员会的电话后,Hinton的第一反应是:「我惊呆了!没有想过这件事会发生在我身上。」 媒体提问环节中有人问到Hinton会使用哪些AI工具,他直接表示:「我经常用GPT-4,虽然它给出的答案不总是对的,但是很有用。」 Geoffrey Hinton发明了一种可以自动发现数据特征的方法,从而执行诸如识别图片中特定元素等任务。
此外,推导可以证明,Hochreiter等人提出的连续态Hopfield网络更新规则,实质上就是Transformer和BERT的注意力机制。 由于在深度神经网络的一次迭代中,每个layer只会被activate一次,因此当考虑把MHNN融合到深度神经网络时,“一步检索” (retrieves patterns in one update step)的能力是非常重要的。实验表明,他们提出的MHNN...

In this opinion piece, the authors, from the fields of artificial intelligence (AI) and psychology, reflect on how the foundational discoveries of Nobel laureates Hopfield and Hinton have influenced their research. They also discuss emerging directions in AI and the challenges that lie ahead for ...

Hopfield Network A Hopfield network is a specific type of recurrent artificial neural network based on the research of John Hopfield in the 1980s on associative neural network models. Hopfield networks are associated with the concept of simulating human memory through pattern recognition and storage....
