研究概况

我的主要方向是人工神经网络,重点关注递归神经网络求解优化问题及相关问题的能力,包括设计新的递归神经网络或者挖掘已有网络的一些新特点。通过对几个代表该领域当前发展水平的高效模型进行归纳总结,我们提出了一个统一的神经网络设计方法,其主要思想是不改变已有神经网络的子模块,而改变各子模块之间的连接关系,得到与原网络性能相当或比原网络性能更好的一系列新模型。利用这个框架,可对每种问题系统地设计出多个模型。此成果的意义在于:一方面,统一了该领域几个知名流派的网络模型,另一方面,大大加快了此类递归神经网络的设计速度。

近年来我开始关注计算神经科学,重点关注认知神经科学对计算机科学的启发。我们试图阐明视觉皮层的层次化结构与深度学习的关系,借鉴视觉信息处理机制的显著性检测,半监督学习的神经科学机制等。同时,我们也通过fMRI实验探索听觉认知的一些机理。
