Neural Network Approach to Portfolio Optimization with Leverage Constraints:a Case Study on High Inflation Investment

no code implementations11 Apr 2023 Chendi Ni, Yuying Li, Peter A. Forsyth

We establish mathematically that the LFNN approximation can yield a solution that is arbitrarily close to the solution of the original optimal control problem with bounded leverage.

A parsimonious neural network approach to solve portfolio optimization problems without using dynamic programming

no code implementations15 Mar 2023 Pieter M. van Staden, Peter A. Forsyth, Yuying Li

We present a parsimonious neural network approach, which does not rely on dynamic programming techniques, to solve dynamic portfolio optimization problems subject to multiple investment constraints.

A Composite T60 Regression and Classification Approach for Speech Dereverberation

no code implementations9 Feb 2023 Yuying Li, Yuchen Liu, Donald S. Williamson

More specifically, we develop a joint learning approach that uses a composite T60 module and a separate dereverberation module to simultaneously perform reverberation time estimation and dereverberation.

Optimal Asset Allocation For Outperforming A Stochastic Benchmark Target

no code implementations27 Jun 2020 Chendi Ni, Yuying Li, Peter Forsyth, Ray Carroll

The proposed framework is illustrated with the asset allocation problem in the accumulation phase of a defined contribution pension plan, with the goal of achieving a higher terminal wealth than a stochastic benchmark.

EREL Selection using Morphological Relation

no code implementations10 Jun 2018 Yuying Li, Mehdi Faraji

In the first round, the pattern in a set of EREL regions is analyzed and used to generate an approximate luminal region.

Nonsmooth Frank-Wolfe using Uniform Affine Approximations

no code implementations16 Oct 2017 Edward Cheung, Yuying Li

Frank-Wolfe methods (FW) have gained significant interest in the machine learning community due to its ability to efficiently solve large problems that admit a sparse structure (e. g. sparse vectors and low-rank matrices).

Projection Free Rank-Drop Steps

no code implementations13 Apr 2017 Edward Cheung, Yuying Li

To address this issue, we propose a rank-drop method for nuclear norm constrained problems.
