Web based Recommender Systems and Rating Prediction
This project implements a recommender system on large dataset of Netflix’s movies. This project also tries to improve recommender systems by incorporating confidence interval and genres of movies. This new approach enhances the performance and quality of service of recommender systems and gives better result than Netflix commercial recommender system, Cinematch

Full-Duplex Relay with Jamming Protocol for Improving Physical-Layer Security
This paper proposes a jointly cooperative relay and jamming protocol based on
full-duplex (FD) capable relay to increase the source-destination secrecy rate
in the presence of different types of eavesdroppers. In this so called
\textit{FD-Relay with jamming (FDJ)} protocol, the FD-Relay, first,
simultaneously receives data and sends jamming to the eavesdropper, and, then,
forwards the data, while the source jams the eavesdropper. Achievable secrecy
rates of the proposed FDJ in presence of different eavesdropper types and
self-interference (SI) are derived and compared with those of the traditional
half-duplex (HD) relay. The adaptive power allocation for secrecy rate
maximization in a multi-carrier scenario for both proposed FDJ and HD-Relay is
formulated as a non-convex optimization problem and corresponding iterative
solution algorithm is developed using the difference-of-two-concave-functions
(DC) programming technique. The simulation results confirm that FDJ offers
significant improvements in the secrecy rate over the HD-Relay.Comment: PIMRC 201
Spillover impacts of the US macroeconomic news: Australian sectoral perspective
We study the spillover effects of the US macroeconomic news on different sectors of the Australian stock market. We find that an indication of economic contractionary from the US raises the conditional mean, and most news elicits the associated volatility in the Australian stock markets. While the US news has been absorbed relatively quickly on the conditional mean, the volatility impact speed is unclear. More importantly, we reveal that the US GDP news has the strongest impact on both the first two moments of the Australian daily returns and help reduce volatility in the latter market.Spillover effects; Macroeconomic news; Australia stock markets; EGARCH
