The model consists of a single unit of recurrent neural network running through a small number of timesteps; the solid arrows illustrate the training progress on each gradient descent step. When the gradient descent model hits the high error wall in the objective function, the gradient is pushed...

With the current set of initial parameters no warning message appears, but if I try to make the set of initial parameters random, it is most likely I get an error/warning message. Specifically I get: "Objective function is returning undefined values at initial point. lsqnonlin cannot continue....

Conventional classifiers will produce an inductive bias toward the majority class because the minority class contributes less to minimizing the objective function. From a learning point of view, however, the minority class usually represents a more critical pattern that deserves more attention [5]. ...
When shooting thick tissue (about 20 μm) or uneven tissue, each focal plane can only image a part of the area, and cannot capture a complete image at the same time. After the sample is layered and imaged through the Z-stack imaging and depth of field expans...
