Minority communities in stochastic block models enter three phases of detectability—detectable, distinguishable, and resolvable—separated by the Kesten-Stigum threshold and two additional thresholds from the eigenvalue structure of the signal matrix.

Detectability of minority communities in networks
Minority communities in stochastic block models enter three phases of detectability—detectable, distinguishable, and resolvable—separated by the Kesten-Stigum threshold and two additional thresholds from the eigenvalue structure of the signal matrix.
