Abstract :
We consider a weak value expansion of the Hermitian operator in terms of a set of operators formed from biorthogonal basis. The utility of the expansion is showcased with examples of spin one-half and spin one systems, where irreversible subset of stochastic matrices describing projective measurement on a mixed state is identified.
