在深度神经网络中通过解调进行抽象学习

Abstract Learning via Demodulation in a Deep Neural Network

University of Surrey(萨里大学)

Andrew J. R. Simpson

摘要:

受大脑的启发,深度神经网络(DNN)被认为通过其层次结构来学习抽象表示。然而,目前,这种情况是如何发生的还不清楚。在这里,我们证明了DNN通过解调过程来学习抽象表示。我们引入了一个有偏的sigmoid激活函数,并使用它来证明DNN在优化解调时学习和性能更好。我们的研究结果构成了DNN在实际应用中进行抽象学习的第一个明确证据。我们的发现也可以解释人类大脑的抽象学习。

英文摘要:

Inspired by the brain, deep neural networks (DNN) are thought to learn abstract representations through their hierarchical architecture. However, at present, how this happens is not well understood. Here, we demonstrate that DNN learn abstract representations by a process of demodulation. We introduce a biased sigmoid activation function and use it to show that DNN learn and perform better when optimized for demodulation. Our findings constitute the first unambiguous evidence that DNN perform abstract learning in practical use. Our findings may also explain abstract learning in the human brain.
