Say I define a probability measure over the symmetric group $S_n$ as follows: - I specify $n$ positive `potential' functions $G_i : \{1, 2, \cdots, N\} \to (0,\infty)$ - I then set $$\mathbb{P}(\sigma) = \frac{1}{Z} \prod_{i=1}^N G_i(\sigma (i))$$ for permutations $\sigma \in S_n$, where $Z$ is a normalisation constant. Is there a name for measures of this form? - It's certainly not completely generic - there are only $\Theta(n^2)$ of these measures over $S_n$, so clearly not every distribution over permutations can be written in this form. - It seems like it should be able to express this condition in terms of some sort of conditional independence relations, but I haven't been able to work out how to do so. If there isn't a specific name for this family of measures, but they do have some useful properties which would otherwise be useful, I'll also be happy to accept answers which indicate this.
