      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 ...

      Neural network methods for one-to-many multi-valued mapping problems 

      Jayne, C.; Lanitis, A.; Christodoulou, Chris C. (2011)
      An investigation of the applicability of neural network-based methods in predicting the values of multiple parameters, given the value of a single parameter within a particular problem domain is presented. In this context, ...
