- Abstract: CRRA utility where the risk aversion coefficient is a constant is commonly
seen in various economics models. But wealth-driven risk aversion rarely shows
up in investor's investment problems. This paper mainly focus on numerical
solutions to the optimal consumption-investment choices under wealth-driven
aversion done by neural network. A jump-diffusion model is used to simulate the
artificial data that is needed for the neural network training. The WDRA Model
is set up for describing the investment problem and there are two parameters
that require to be optimized, which are the investment rate of the wealth on
the risky assets and the consumption during the investment time horizon. Under
this model, neural network LSTM with one objective function is implemented and
shows promising results.

This paper proposes an effective algorithm based on neural networks to take advantage of these investment products.
A deep neural network, which outputs the allocation weight of each asset at a time interval, is trained to maximize the Sharpe ratio.
A novel loss term is proposed to regulate the network's bias towards a specific asset, thus enforcing the network to learn an allocation strategy that is close to a minimum variance strategy.
