Seeding Influential Nodes in Non-Submodular Models of Information Diffusion
Elliot Anshelevich, Ameya Hate, Malik Magdon-Ismail
We consider the model of information diffusion in social networks from \cite{Hui2010a} which incorporates trust (weighted links) between actors, and allows actors to actively parti…
Spreading Processes and Large Components in Ordered, Directed Random Graphs
Paul Horn, Malik Magdon-Ismail
Order the vertices of a directed random graph \math{v_1,...,v_n}; edge \math{(v_i,v_j)} for \math{i<j} exists independently with probability \math{p}. This random graph model is re…
Efficient Computation of Optimal Trading Strategies
Victor Boyarshinov, Malik Magdon-Ismail
Given the return series for a set of instruments, a \emph{trading strategy} is a switching function that transfers wealth from one instrument to another at specified times. We pres…
Comparing Prediction Market Structures, With an Application to Market Making
Aseem Brahma, Sanmay Das, Malik Magdon-Ismail
Ensuring sufficient liquidity is one of the key challenges for designers of prediction markets. Various market making algorithms have been proposed in the literature and deployed i…
Row Sampling for Matrix Algorithms via a Non-Commutative Bernstein Bound
Malik Magdon-Ismail
We focus the use of \emph{row sampling} for approximating matrix algorithms. We give applications to matrix multipication; sparse matrix reconstruction; and, \math{\ell_2} regressi…
