Evolutionary dynamics in financial markets with heterogeneities in strategies and risk tolerance

no code implementations18 Oct 2020 Wen-Juan Xu, Chen-Yang Zhong, Fei Ren, Tian Qiu, Rong-Da Chen, Yun-Xin He, Li-Xin Zhong

For a heterogeneous population, the coexistence of investors with pair pattern strategies and reference point strategies causes the price to have a slow fluctuation around a typical equilibrium point and both a large price fluctuation and a no-trading state are avoided, in which the pair pattern strategies push the system far away from the equilibrium while the reference point strategies pull the system back to the equilibrium.

In this work, we propose "global style tokens" (GSTs), a bank of embeddings that are jointly trained within Tacotron, a state-of-the-art end-to-end speech synthesis system.
