Meanings of differentiable in English

Such an object has no smoothness; in mathematical terms, it is not differentiable.

And yet two of the terms in the KPZ equation call for the object to be differentiable.

In this paper, we propose a differentiable global-flow local-attention framework to reassemble the inputs at the feature level.

Main results: Participants were capable of generating robust cortical modulation that was differentiable across attempted arm and hand movements of their paralyzed limb.
