Optimizer weight_decay
WebMar 5, 2016 · Can it be useful to combine Adam optimizer with decay? I haven't seen enough people's code using ADAM optimizer to say if this is true or not. If it is true, perhaps it's because ADAM is relatively new and learning rate decay "best practices" haven't been established yet. ... height and weight - creating data calculating bmi, and if over 27 ...
