Deep learning techniques are increasingly being adopted for classification
tasks over the past decade, yet explaining how deep learning architectures can
achieve state-of-the-art performance is still an elusive goal. While all the
training information is embedded deeply in a trained model, we still do not
understand much about its performance by only analyzing the model. This paper
examines the neuron activation patterns of deep learning-based classification
models and explores whether the models' performances can be explained through
neurons' activation behavior. We propose two approaches: one that models
neurons' activation behavior as a graph and examines whether the neurons form
meaningful communities, and the other examines the predictability of neurons'
behavior using entropy. Our comprehensive experimental study reveals that both
the community quality (modularity) and entropy are closely related to the deep
learning models' performances, thus paves a novel way of explaining deep
learning models directly from the neurons' activation pattern.

关于深度学习架构中神经元社区的演变
在过去的十年中,深度学习技术越来越多地被用于分类任务,但解释深度学习架构如何实现最先进的性能仍然是一个难以实现的目标。虽然所有的训练信息都深深地嵌入在一个训练好的模型中,但仅通过分析模型,我们仍然对其性能了解不多。本文研究了基于深度学习的分类模型的神经元激活模式,并探讨了模型的性能是否可以通过神经元的激活行为来解释。我们提出了两种方法:一种将神经元的激活行为建模为图形并检查神经元是否形成有意义的社区,另一种方法使用熵检查神经元行为的可预测性。
