Coarse-graining Markov state models with PCCA
Coarse-graining Markov state models • Coarse-graining Markov state models here means finding a smaller transition matrix that does a similar job as the large original transition matrix.
Coarse-graining Markov state models • Coarse-graining Markov state models here means finding a smaller transition matrix that does a similar job as the large original transition matrix. • We have already seen eigendecomposition as a way of reducing the dimension of a transition matrix. Let’s take this as our starting point…

• The dominant eigenvectors can be linearly transformed into indicator functions for the metastable states. • These indicators are called metastable memberships.

Connection to HMMs (Simon‘s talk) metastable_memberships • metastable_distributions
Connection to VAMPnets • Soft-max VAMPnets fit indicator functions directly to the transition pairs. • The indicator functions are modelled as sigmoids.
