Neutrino-photon scattering and its crossed processes in a background magnetic fieldJul 16 1999Oct 12 1999We study the neutrino-photon processes such as $\gamma\gamma\to \nu\bar{\nu}$ and $\nu\gamma\to \nu\gamma$ in a background magnetic field smaller than the critical magnetic field $B_c\equiv m_e^2/e$. Using Schwinger's proper-time method, we extract leading ... More

Deep Q-Networks for Accelerating the Training of Deep Neural NetworksJun 05 2016Aug 01 2016We present a method, called QAN, for improving the generalization ability of a deep neural network (DNN). It achieves this by using a deep Q-network (DQN) to learn policies to control some behaviors of the DNN during training across episodes. We feed ... More

How does cell size regulation affect population growth?Nov 23 2016The proliferation of a growing microbial colony is well characterized by the population growth rate. However, at the single-cell level, isogenic cells often exhibit different cell-cycle durations. For evolutionary dynamics, it is thus important to establish ... More

Group Invariant Deep Representations for Image Instance RetrievalJan 09 2016Jan 13 2016Most image instance retrieval pipelines are based on comparison of vectors known as global image descriptors between a query image and the database images. Due to their success in large scale image classification, representations extracted from Convolutional ... More
