  Deep learning has been shown to outperform traditional machine learning
algorithms across a wide range of problem domains. However, current deep
learning algorithms have been criticized as uninterpretable "black-boxes" which
cannot explain their decision making processes. This is a major shortcoming
that prevents the widespread application of deep learning to domains with
regulatory processes such as finance. As such, industries such as finance have
to rely on traditional models like decision trees that are much more
interpretable but less effective than deep learning for complex problems. In
this paper, we propose CLEAR-Trade, a novel financial AI visualization
framework for deep learning-driven stock market prediction that mitigates the
interpretability issue of deep learning methods. In particular, CLEAR-Trade
provides a effective way to visualize and explain decisions made by deep stock
market prediction models. We show the efficacy of CLEAR-Trade in enhancing the
interpretability of stock market prediction by conducting experiments based on
S&P 500 stock index prediction. The results demonstrate that CLEAR-Trade can
provide significant insight into the decision-making process of deep
learning-driven financial models, particularly for regulatory processes, thus
improving their potential uptake in the financial industry.
