Portfolio may refer to: a collection of held stocks or investments (finance), or patents held by a single entity; a sample of an individual's past work (art, education, photography, development), or a display case (physical or virtual) used to display artwork, photographs, etc. Anyways, I wonder if people use LSTM for reinforcement learning. I can imagine environment state to be input, with action as output. Whenever action is chosen it is executed and reward is calculated.

Inverse reinforcement learning or IRL deals with problems where we only observe states and actions but not rewards. The problem of IRL is to find the actual reward function and the optimal policy from data. In general, it's more complex problem than the direct reinforcement learning because now we have to find two functions rather than just one ... hence as a stochastic optimal control, where the system being controlled is a portfolio consisting of multiple investment components, and the control is its component weights. Consequently, the problem could be solved using model-free Reinforcement Learning (RL) without knowing specific component dynamics.

Therefore the framework of (D)RL seems appropriate for portfolio optimization where we are interested in maximizing a certain objective (say Sharpe's ratio) over a longer period. However, many papers that deal with (D)RL applications in portfolio optimization use historical market data to build a deterministic MDP to train the model on. Reinforcement learning is one of three basic machine learning paradigms, alongside supervised learning and unsupervised learning. In reinforcement learning, algorithm learns to perform a task simply by trying to maximize rewards it receives for its actions (example – maximizes points it receives for increasing returns of an investment portfolio).

portfolio optimization have been intensively studied in reinforcement learning [6,8–10]. In this paper, we confine our main interest on trading the individual stocks in the market. The works with the stock price prediction based on supervised learning [5,11] lack in considering the risk management and portfolio optimiza-tion. See full list on github.com

A reinforcement learning policy observes the history H t at time taiming to control the cost incurred. That is, the policy ˇ is a (possibly random) mapping which designs the input sequence fu(t)g1 t=0 according to the history available up to that time; u(t) = ˇ(H t;Q x;Q u); (3) so that the average cost is minimized.
