摘要:

神经网络在持续学习的环境中挣扎,避免灾难性的遗忘:当尝试被阻止时,新的学习可能会覆盖以前的学习。人类在这些环境中有效地学习,在某些情况下甚至表现出阻塞的优势,这表明大脑包含克服这个问题的机制。在这里,我们建立在以前的工作,并表明,神经网络配备了认知控制的机制,不表现出灾难性的遗忘时,审判被阻止。我们进一步展示了当控制信号中存在用于主动维护的偏置时,阻塞超过交织的优点,这意味着维护和控制强度之间的权衡。对网络学习到的类似地图的表示的分析为这些机制提供了更多的见解。我们的工作突出了认知控制在神经网络中帮助持续学习的潜力,并为在人类中观察到的阻塞优势提供了解释。

英文摘要:

Neural networks struggle in continual learning settings from catastrophic forgetting: when trials are blocked, new learning can overwrite the learning from previous blocks. Humans learn effectively in these settings, in some cases even showing an advantage of blocking, suggesting the brain contains mechanisms to overcome this problem. Here, we build on previous work and show that neural networks equipped with a mechanism for cognitive control do not exhibit catastrophic forgetting when trials are blocked. We further show an advantage of blocking over interleaving when there is a bias for active maintenance in the control signal, implying a tradeoff between maintenance and the strength of control. Analyses of map-like representations learned by the networks provided additional insights into these mechanisms. Our work highlights the potential of cognitive control to aid continual learning in neural networks, and offers an explanation for the advantage of blocking that has been observed in humans.
