Web14 Jan 2024 · If the gradients associated with a pixel are small in magnitude, then that pixel is likely to be unimportant to the prediction (since small changes in the pixel's value translate to small changes in network outputs). By contrast, if the magnitudes of the gradients are large, then it signifies that the pixel is important to the prediction.

Webmean gradient is being considered as most important marker for assessment of prosthetic valve function. It is very important to document patient's baseline mean gradient in early postoperative period because these gradients can be used in future detection of prosthesis malfunction.5 Emerson et al studied mean gradient in 180 St Jude Webregional, operating on steep gradients, and urban ones.
