Use this code to replace string in PDF. Learning Rate The learning rate controls the size of each step toward the minimum of the objective function If the learning rate is too small, the weight adjustments are correspondingly small More learning iterations are then required to reach a local minimum However, the search path will closely approximate the gradient path Figure 75(a) illustrates the e ect of small On the other hand, large will have large weight updates Convergence will initially be fast, but the algorithm will eventually oscillate without reaching the minimum It is also possible that too large a learning rate will cause jumping over a good local minimum proceeding toward a bad local minimum Figure 75(b) illustrates the oscillating behavior, while Figure 75(c) illustrates how large learning rates may cause the network to overshoot a good minimum and get trapped in a bad local minimum Small learning rates also have the disadvantage of being trapped in a bad local minimum as illustrated in Figure 75(d) The search path goes down the rst local minimum, with no mechanism to move out of it toward the next, better minimum Of course, the search trajectory depends on the initial starting position If the second initial point is used, the NN will converge to the better local minimum But how should the value of the learning rate be selected One approach is to nd the optimal value of the learning rate through cross-validation, which is a lengthy process An alternative is to select a small value (eg 01) and to increase the value if convergence is too slow, or to decrease it if the error does not decrease fast enough Plaut et al [680] proposed that the learning rate should be inversely proportional to the fanin of a neuron This approach has been theoretically justi ed through an analysis of the eigenvalue distribution of the Hessian matrix of the objective function [167] Several heuristics have been developed to dynamically adjust the learning rate during training One of the simplest approaches is to assume that each weight has a di erent learning rate kj The following rule is then applied to each weight before that weight is updated: if the direction in which the error decreases at this weight change is the same as the direction in which it has been decreasing recently, then kj is increased; if not, kj is decreased [410] The direction in which the error decreases is determined by the sign of the partial derivative of the objective function with respect to the weight Usually, the average change over a number of pattern presentations is considered and not just the previous adjustment An alternative is to use an annealing schedule to gradually reduce a large learning rate to a smaller value (refer to quation 440) This allows for large initial steps, and ensures small steps in the region of the minimum. replace text in pdf using java: How to read all the text from pdf document using PDFBox 2.0 java code to extract text from pdf How to extract text from PDF in Java - YouTube
