They differ in their effectiveness, a factor that may help explain why resource allocations vary across health conditions and do not correspond closely with disease burden.

Four Questions on Birkhoff Polytope

We ask several questions on the structure of the polytope of doubly stochastic n n matrices Pn, known as a Birkhoo polytope. We discuss the volume of Pn, the work of the simplex method, and the mixing of random walks Pn.

Identify Keywords for Stack Exchange Questions

We leveraged a wide range of knowledge in machine learning and information retrieval to develop a robust keywords identification system. In particular, we adapted the Tf-Idf heuristic for feature selection, investigated linear regression, logistic regression, and SVM for predicting number of keywords (tags), and also implemented NaiveBayes, Labeled Latent Dirichlet Allocation(L-LDA) algorithms ...
