Fractional order graph neural network

no code implementations5 Jan 2020 Zijian Liu, Chunbo Luo, Shuai Li, Peng Ren, Geyong Min

This paper proposes fractional order graph neural networks (FGNNs), optimized by the approximation strategy to address the challenges of local optimum of classic and fractional graph neural networks which are specialised at aggregating information from the feature and adjacent matrices of connected nodes and their neighbours to solve learning tasks on non-Euclidean data such as graphs.

Realized volatility and parametric estimation of Heston SDEs

no code implementations14 Jun 2017 Robert Azencott, Peng Ren, Ilya Timofeyev

We present a detailed analysis of \emph{observable} moments based parameter estimators for the Heston SDEs jointly driving the rate of returns $R_t$ and the squared volatilities $V_t$.
