A double pendulum is a pendulum with another pendulum attached to its end. In is example, instead of learning from a well-described equation of motion, we train the model with the famous dataset provided by IBM. The equation of motion to the real experiments of double pendulum is learned by a two-dimensional Fourier neural operator. It learns to inference the next 30 steps with the given first 30 steps. The result of this example can be found here.
By inference the result recurrently, we can generate up to 150 steps with the first 30 initial steps.
Change directory to example/DoublePendulum and use following commend to train model:
julia> using DoublePendulum;
DoublePendulum.train();
$ julia --proj
