loss_weights 确实可以在一开始将4个任务的学习率增大 1,5,10 和 10 倍。但并没有对不同的任务使用不同的优化算法,除非最后一个选项 optimizer=opt 改成, 根据Keras 文档中对 compile 函数的描述,optimizer 表示一个优化函数,而不是一个列表。而 loss_weights 是要用在加权求和中,得到一个整体的 loss,然后...

If you supply weights, loss normalizes them so that the observation weights in each class sum to the prior probability of that class. If you specify Weights as a numeric vector, the size of Weights must be equal to the number of observations in X or tbl. The software normalizes Weights ...
And even if you don’t have any “weights” at all, I show you how you can get around that limitation by using regular household items in their place. No gym membership required! Of course, if you do have a gym membership, you can certainly do these workouts (and wow your friends wi...

And when I finally did make time to exercise, my hour in the gym felt miserable… I felt ridiculous fumbling with all the weights and machines. I couldn’t actually work out for more than a couple minutes before breaking down into a pile of sweat and fat. I never seemed to get stronge...
“If you’re lifting weights, that means doing the same exercise with heavier weights,” Matheny says. “If it’s cardio, it means you’re moving at a faster pace than you were before.” Overall, Matheny says that intensity either comes down to weights or speed. ...
