Topic: "Mixture of Expert Models in Quantitative Trading"

Short Abstract: We will introduce the Mixture of Experts models and demonstrate their behavior with a toy example using synthetic data. We will go through a real-world Mixture of Experts neural network applied to quantitative trading using our in-house trading signals, and discuss aspects of the prediction problem which are specific to the portfolio construction and trading application.
