  It is commonly assumed that individuals tend to be more similar to their friends than to strangers. We view the observed social network as a noisy signal about the latent "social space": a structure that captures in what ways and to which extent the individuals are (dis)similar. This naturally raises the inverse question: given a social network, how accurately can we reconstruct the social space?
