A Cost Analysis of the Jan Aushadhi Scheme in India

Medicines constitute a substantial proportion of out-of-pocket (OOP) expenses in Indian households. In order to address this issue, the Government of India launched the Jan Aushadhi (Medicine for the Masses) Scheme (JAS) to provide cheap generic medicines to the patients (http://janaushadhi.gov.in/about_jan_aushadhi.html). These medicines are provided through the Jan Aushadhi stores established...

Multiple Random Oracles Are Better Than One

We study the problem of learning k-juntas given access to examples drawn from a number of different product distributions. Thus we wish to learn a function f : {−1, 1}n → {−1, 1} that depends on k (unknown) coordinates. While the best known algorithms for the general problem of learning a k-junta require running time of n poly(n, 2), we show that given access to k different product distribution...

Region and Contour Identification of Physical Objects

The region occupied by and the contour of a physical object in 3-dimensional space are in a way dual or interchangeable characteristics of the object: the contour is the region’s boundary and the region is contained inside the contour. In the same way the characterization of the object’s contour by its Fourier descriptors, and the reconstruction of its region from the object’s multidimensional ...
