             Summary: Add activation code for Horn
                 Key: HORN-33
                 URL: https://issues.apache.org/jira/browse/HORN-33
             Project: Apache Horn
          Issue Type: Improvement
          Components: build
            Reporter: Kwihoon Kim
            Priority: Minor


This implements a Parametric Rectified Linear Unit (PReLU) that generalizes the traditional rectified unit. [1]
PReLU improves model fitting with nearly zero extra computational cost and little overfitting risk. Second, we derive a robust initialization method that particularly considers the rectifier nonlinearities. 
This method enables us to train extremely deep rectified models directly from scratch and to investigate deeper or wider network architectures. Based on the learnable activation and advanced initialization, we achieve 4.94% top-5 test error on the ImageNet 2012 classification dataset. This is a 26% relative improvement over the ILSVRC 2014 winner (GoogLeNet, 6.66%). 
To our knowledge, our result is the first to surpass the reported human-level performance (5.1%) on this dataset.
