Summary
The paper introduces soft diamond regularizers for training deep neural classifiers, which improve synaptic sparsity and classification accuracy. These regularizers are based on symmetric alpha-stable (SαS) bell-curve weight priors, which have thicker tails than Gaussian priors. The paper also proposes an efficient way to compute the derivative of the log-priors using a lookup table.
Highlights
- Soft diamond regularizers improve synaptic sparsity and classification accuracy in deep neural networks.
- SαS weight priors have thicker tails than Gaussian priors, leading to better generalization and robustness.
- The proposed lookup table method reduces computational complexity in estimating the derivative of log-priors.
- The regularizers outperform L1 and L2 regularizers in terms of classification accuracy and sparsity.
- Combining soft diamond regularizers with dropout, batch normalization, and data augmentation further improves performance.
- The regularizers are effective in both convolutional and residual network architectures.
- The paper demonstrates the effectiveness of the regularizers on CIFAR-10, CIFAR-100, and Caltech-256 datasets.
