Our major contribution is that we incorporated multiple networks from the publication dataset, such as the paper citation network, author citation network, author(More)
The reinforcement learning methods are applied to optimize the portfolios with asset allocation between risky and riskless instruments in this paper. We use classic reinforcement algorithm, Q-learning, to evaluate the performance in terms of cumulative profits by maximizing different forms of value functions: interval profit, sharp ratio, and derivative(More)
We are developing a 1 mm(3) resolution positron emission tomography camera dedicated to breast imaging. The camera collects high energy photons emitted from radioactively labeled agents introduced in the patients in order to detect molecular signatures of breast cancer. The camera comprises many layers of lutetium yttrium oxyorthosilicate (LYSO)(More)
