to_unconstrained
to_unconstrained(params, metadata)Map constrained free_params to an unconstrained dict.
Applies per-param invertible transforms based on metadata[k].bounds:
[lo, hi]— logit:u = log(v / (1 - v))wherev = (param - lo) / (hi - lo)[lo, ∞)— softplus⁻¹:u = log(exp(param - lo) - 1)- unbounded — identity:
u = param
