Rationale behind the parameter values in TenSEAL #471

Question

Can you please explain the thought behind keeping the parameter values for poly_mod_degree as 4096 or 8192 and coeff_mod_bit_sizes as [40,20,40] or [40,21,21,...,42].

Further Information

I am doing my final year project that uses ML and FHE. It would be great to have some insights behind the usage of specific parameter values. I went through the ICLR paper for TenSEAL as well.

I can recommend this blog post which helped me a lot in understanding the ckks algo and its parameters:
