Sine wave regression using Reptile
In the last section, we saw how Reptile works. Now, we'll understand Reptile better by coding it from scratch. Let's say we have a collection of tasks and the goal of each task is to regress the output of the sine wave given some input. So what do we mean by that?
Let's say y = amplitude*sin(x+phase). The goal of our algorithm is to learn to regress the value of y given x. The value of amplitude is chosen randomly between 0.1 and 5.0 and the value of phase is chosen randomly between 0 and 
. So, for each of the tasks, we sample only 10 data points and train the network—that is, for each of the tasks, we sample ...
