Gradient Descent vs Adagrad vs Momentum in TensorFlow

WebTo construct an Optimizer you have to give it an iterable containing the parameters (all should be Variable s) to optimize. Then, you can specify optimizer-specific options such as the learning rate, weight decay, etc. Example: optimizer = optim.SGD(model.parameters(), lr=0.01, momentum=0.9) optimizer = optim.Adam( [var1, var2], lr=0.0001) WebOct 28, 2024 · Figure 5 shows the idea behind the gradient adapted learning rate. When the cost function curve is steep, the gradient is large, and the momentum factor ‘Sn’ is larger. Hence the learning rate is smaller. When the cost function curve is shallow, the gradient is small and the momentum factor ‘Sn’ is also small. The learning rate is larger. iris wireless bankruptcy https://bowden-hill.com
