COVID-MTL: Multitask learning with Shift3D and random-weighted loss for COVID-19 diagnosis and severity assessment

作者:

Highlights:

• Automated and simultaneous detection and severity assessment of COVID-19 using CT.

• Tackle under segmentation of ground-glass opacities in COVID-19 chest CT scans.

• 3D CNNs boosted by shifting low-level feature representations of volumetric inputs.

• COVID-19 multitask learning performance improved by random-weighted loss function.

• Identified features significantly related to positivity and severity of COVID-19.
