Ensembling Neural Networks for Improved Prediction and Privacy in Early Diagnosis of Sepsis

1 code implementation1 Sep 2022 Shigehiko Schamoni, Michael Hagmann, Stefan Riezler

Ensembling neural networks is a long-standing technique for improving the generalization error of neural networks by combining networks with orthogonal properties via a committee decision.

On-the-Fly Aligned Data Augmentation for Sequence-to-Sequence ASR

1 code implementation3 Apr 2021 Tsz Kin Lam, Mayumi Ohta, Shigehiko Schamoni, Stefan Riezler

Our method, called Aligned Data Augmentation (ADA) for ASR, replaces transcribed tokens and the speech representations in an aligned manner to generate previously unseen training pairs.
