In this competition, your challenge is to uncover the hidden generating function behind the data by fitting a bivariate polynomial model (that’s just a fancy way of saying “a polynomial with two variables”). But beware—the data isn’t perfectly clean, it’s noisy, which makes the task more challenging!

✨**Your Mission**: Approximate the true parameters (the coefficients of the polynomial) as closely as possible, and in doing so, reconstruct the generating function.
