And in principle, at least, this should be enough to recover the coefficients.

至少原则上，这应该足以恢复系。

Since again it's a point wise operation and with polynomials, you only need finitely mini samples to be able to recover the coefficients.

由于这又是一个逐点运算并且有多项式，因此您只需要有限的迷你能够恢复系。

You sample those polynomials at enough outputs, multiply those samples point wise, and then solve the system to recover the coefficients as a sneaky backdoor way to find the convolution.

您以足够的输出对这些多项式进行采，将这些逐点相乘， 然后求解系统以恢复系， 作为找到卷积的一种偷偷摸摸的后门方法。
