- Title: Evolving Neural Selection with Adaptive Regularization
- Authors: Li Ding and Lee Spector
- Abstract summary: We show a method in which the selection of neurons in deep neural networks evolves, adapting to the difficulty of prediction.
We propose the Adaptive Neural Selection (ANS) framework, which evolves to weigh neurons in a layer to form network variants.
Experimental results show that the proposed method can significantly improve the performance of commonly-used neural network architectures.

- Abstract: Over-parameterization is one of the inherent characteristics of modern deep
neural networks, which can often be overcome by leveraging regularization
methods, such as Dropout. Usually, these methods are applied globally and all
the input cases are treated equally. However, given the natural variation of
the input space for real-world tasks such as image recognition and natural
language understanding, it is unlikely that a fixed regularization pattern will
have the same effectiveness for all the input cases. In this work, we
demonstrate a method in which the selection of neurons in deep neural networks
evolves, adapting to the difficulty of prediction. We propose the Adaptive
Neural Selection (ANS) framework, which evolves to weigh neurons in a layer to
form network variants that are suitable to handle different input cases.
Experimental results show that the proposed method can significantly improve
the performance of commonly-used neural network architectures on standard image
recognition benchmarks. Ablation studies also validate the effectiveness and
contribution of each component in the proposed framework.

Denoising [3.591122855617648]
We propose a methodology for adapting existing neural networks so that normalization-equivariance holds by design.
Our main claim is that not only ordinary convolutional layers, but also all activation functions, should be completely removed from neural networks.
Experimental results in image denoising show that normalization-equivariant neural networks, in addition to their better conditioning, also provide much better generalization across noise levels.
