what is the meaning of "amp" and "phase"?

[ucasiggcas]

Dear,

In my project for predicting the stock price, I only have input data(n features) and label(price), what will I do for the amp and phase?

I just want to use my data for training.

Thanks.

they are used for regression task--sinusoid. y = amp* sin(x+phase).
