Performance functions and reinforcement learning for trading systems and portfolios
Article Abstract:
A technique for training trading systems and portfolios that uses reinforcement learning algorithms to optimize objective functions that directly measure trading and investment performance is proposed. Performance functions such as profit and wealth, the Sharpe ratio and a proposed differential Sharpe ratio were optimized to test the methodology. Results affirm the efficacy of some of the proposed methods for optimizing trading systems and portfolios.

The evolution of conventions
Article Abstract:
An analysis of the development of conventions and the role of expectations with more than one equilibrium condition is presented. The analysis develops a repeated n-game by various agents who draw individual strategies based on information about what other agents have done before. It is shown that a stochastic process which converges to a pure strategy Nash equilibrium can be developed. This process generates stochastically stable equilibria.

Bayesian learning behaviour and the stability of equilibrium forecasts
Article Abstract:
A learning model incorporating Bayesian characteristics and set in a stochastic environment is discussed. This model incorporates rational expectations about the state which involve forecasts and beliefs. These are updated continually and form part of a dynamic learning interaction. It is shown that full learning does not always happen. Nonetheless, partial learning has its results which come in the form of better informed predictions.
