The overlap gap property in principal submatrix recovery
Abstract We study support recovery for a $$k \times k$$ k × k principal submatrix with elevated mean $$\lambda /N$$ λ / N , hidden in an $$N\times N$$ N × N symmetric mean zero Gaussian matrix. Here $$\lambda >0$$ λ > 0 is a universal constant, and we assume $$k = N \rho $$ k = N ρ for some co...
