Lastly, the limitation of only testing on a single market was additionally addressed by conducting checks on three markets from completely different economies with completely different total value trends. Nevertheless, contemplating the overlapping confidence intervals for the vast majority of the frontiers in all three markets, it seems that none of these policy networks might considerably outperform any of the others consistently. For the Dow 30 market, all three policy networks carried out very similarly for all the excess risk and return ranges. As soon as all these points in risk-return area had been obtained, the non-dominated set was determined by choosing all factors for which the maximum excess return was obtained with out increasing excess risk. Outfitted with the transition probabilities, we now concentrate on selecting the reward perform which shapes the objective of the coverage learning course of.
PPO managed to provide barely more excess returns utilizing the non-linear transaction price perform, whereas DDPG and A2C each produced higher excess returns with the linear transaction value function.

The shaded gray area on each chart indicates the testing period, whereas the non-shaded area indicates the coaching period. This non-dominated constituted the Pareto optimum frontier, which was a set of optimum portfolios to carry through the check interval. Fig. 7 exhibits the mean Pareto frontiers (along with their 95% confidence intervals) produced by FRONTIER when utilizing different coverage network architectures.
