Derivation of the Closed-Form Solution to the Mori Formula

Journal of the Physical Society of Japan, 1997
Summary: The closed-form solution to the memory function in the generalized Langevin equation (Mori formula), obtained as a series expansion in terms of the projection operator, is rederived without use of the expansion method. The procedure for approximation of the closed-form solution is briefly mentioned.

Closed form solution of similarity algorithms

Proceedings of the 33rd international ACM SIGIR conference on Research and development in information retrieval, 2010
Algorithms defining similarities between objects of an information network are important of many IR tasks. SimRank algorithm and its variations are popularly used in many applications. Many fast algorithms are also developed. In this note, we first reformulate them as random walks on the network and express them using forward and backward transition ...
