Why have a Unified Predictive Uncertainty? Disentangling it using Deep Split Ensembles

1 code implementation25 Sep 2020 Utkarsh Sarawgi, Wazeer Zulfikar, Rishab Khincha, Pattie Maes

Our work further demonstrates its applicability in a multi-modal setting using a benchmark Alzheimer's dataset and also shows how deep split ensembles can highlight hidden modality-specific biases.

Multimodal Inductive Transfer Learning for Detection of Alzheimer's Dementia and its Severity

1 code implementation30 Aug 2020 Utkarsh Sarawgi, Wazeer Zulfikar, Nouran Soliman, Pattie Maes

Our system achieves state-of-the-art test accuracy, precision, recall, and F1-score of 83. 3% each for AD classification, and state-of-the-art test root mean squared error (RMSE) of 4. 60 for MMSE score regression.
