Before revision:  For this purpose, we combine three different deep neural network structures in a novel way: a feedforward network to capture non-linearities, a recurrent Long-Short-Term-Memory network to find a small set of  economic state processes and a generative adversarial network to identify the portfolio strategies with the least explained pricing information .
