Different from the standard encoder-decoder structure, ShelfNet has multiple encoder-decoder branch pairs with skip connections at each spatial level, which looks like a shelf with multiple columns. The shelf-shaped structure provides multiple paths for information U-Net has been providing state-of-the-art performance in many medical image segmentation problems. Many modifications have been proposed for U-Net, such as attention U-Net, recurrent residual convolutional U-Net (R2-UNet), and U-Net with residual blocks or blocks with dense connections. However, all these modifications have an encoder-decoder structure with skip connections, and the number of Neural ordinary differential equations (NODEs) have recently attracted increasing attention; however, their empirical performance on benchmark tasks (e.g. image classification) are significantly inferior to discrete-layer models.

To our knowledge, MALI is the first ODE solver to enable efficient training of CNN-ODEs on large-scale dataset such as ImageNet. Other methods are not applicable to complicated systems for various reasons: the adjoint method suffer from inaccuracy in gradient estimation, because it forgets the forward-time trajectory, and the reconstructed reverse-time trajectory cannot match forward-time Juntang Zhuang (Preferred) Suggest Name; Emails.

Adaptive Checkpoint Adjoint method In automatic differentiation, ACA applies a trajectory checkpoint strategy which records the forward-mode trajectoryas the reverse-mode trajectory to guarantee accuracy; ACA deletes redundant components forshallow computation graphs; and ACA supports adaptive solvers.

We demonstrate an explanation for their poorer performance is the inaccuracy of existing gradient estimation methods: the adjoint method has numerical errors in 2020-05-22 · BrainGNN: Interpretable Brain Graph Neural Network for fMRI Analysis 3 43 retrieve ROI clustering patterns.

In region 3 , we demonstrate AdaBelief’s advantage over Adam in the “large gradient, small curvature” case.
