WebNov 19, 2024 · What should the data scientist do to improve the training process?" A. Increase the learning rate. Keep the batch size the same. [REALISTIC DISTRACTOR] B. Reduce the batch size. Decrease the learning rate. [CORRECT] C. Keep the batch size the same. Decrease the learning rate. WebSimulated annealing is a technique for optimizing a model whereby one starts with a large learning rate and gradually reduces the learning rate as optimization progresses. Generally you optimize your model with a large learning rate (0.1 or so), and then progressively reduce this rate, often by an order of magnitude (so to 0.01, then 0.001, 0. ...
WebDec 1, 2024 · For a learning rate of 0.0001, the difference was mild; however, the highest AUC was achieved by the smallest batch size (16), while the lowest AUC was achieved by the largest batch size (256). Table 2 shows the result of the SGD optimizer with a learning rate of 0.001 and a learning rate of 0.0001. WebJan 4, 2024 · Ghost batch size 32, initial LR 3.0, momentum 0.9, initial batch size 8192.

Web1 day ago · From Fig. 3 (a), it can be seen that as the batch size increases, the overall accuracy decreases. Fig. 3 (b) reflects that as the learning rate increased, the overall accuracy increased at first and then decreased to the maximum value when the learning rate is 0.1. So the batch size and learning rate of CNN were set as 100 and 0.1. WebNov 22, 2024 · If the factor is larger, the learning rate will decay slower. If the factor is smaller, the learning rate will decay faster. The initial learning rate was set to 1e-1 using SGD with momentum with momentum parameter of 0.9 and batch size set constant at 128. Comparing the training and loss curve to experiment-3, the shapes look very similar.
