      Isolating stock prices variation with neural networks 

      Draganova, C.; Lanitis, A.; Christodoulou, Chris C. (2009)
      In this study we aim to define a mapping function that relates the general index value among a set of shares to the prices of individual shares. In more general terms this is problem of defining the relationship between ...
