Webb16 dec. 2009 · This could add an innovative label-free assay technology to advance the speed and relevance of measuring binding reactions. The drive toward greater sensitivity and miniaturisation has been a goal in drug discovery and diagnostics. Advances made in the broad field of nanotechnology are being applied to this application. WebbCompared to CNN, self-attention increases the receptive field without increasing the computational cost associated with kernel sizes. In addition, self-attention is invariant to permutations and changes in the number of input points, hence it can easily operate on irregular inputs instead of the standard convolution that requires a grid structure [ 52 , 64 ].
