SAE: Single Architecture Ensemble Neural Networks

Ensembles of separate neural networks (NNs) have shown superior accuracy and confidence calibration over single NN across tasks. Recent methods compress ensembles within a single network via early exits or multi-input multi-output frameworks. However, the landscape of these methods is fragmented thus far, making it difficult to choose the right approach for a given task. Furthermore, the algorithmic performance of these methods is behind the ensemble of separate NNs and requires extensive architecture tuning. We propose a novel methodology unifying …
