    Leverage Financial News to Predict Stock Price Movements Using Word Embeddings and Deep Neural Networks

    Full text link
    Financial news contains useful information on public companies and the market. In this paper we apply the popular word embedding methods and deep neural networks to leverage financial news to predict stock price movements in the market. Experimental results have shown that our proposed methods are simple but very effective, which can significantly improve the stock prediction accuracy on a standard financial database over the baseline system using only the historical price information.Comment: 5 pages, 2 figures, technical repor

    Gravity/Fluid Correspondence and Its Application on Bulk Gravity with U(1)U(1) Gauge Field

    As the long wavelength limit of the AdS/CFT correspondence, the gravity/fluid correspondence has been shown to be a useful tool for extracting properties of the fluid on the boundary dual to the gravity in the bulk. In this paper, after briefly reviewing the algorithm of gravity/fluid correspondence, we discuss the results of its application on bulk gravity with a U(1)U(1) gauge field. In the presence of a U(1)U(1) gauge field, the dual fluid possesses more interesting properties such as its charge current. Furthermore, an external field AμextA_\mu^{ext} could affect the charge current, and the U(1)U(1) Chern-Simons term also reinduces extra structures to the dual current giving anomalous transport coefficients.Comment: 14 pages, no figure, version publishe
