Inverse Design of Photonic Crystal Surface Emitting Lasers is a Sequence Modeling Problem

no code implementations8 Mar 2024 Ceyao Zhang, Renjie Li, Cheng Zhang, Zhaoyu Zhang, Feng Yin

By modeling the inverse design of PCSEL as a sequential decision-making problem, RL approaches can construct a satisfactory PCSEL structure from scratch.

POViT: Vision Transformer for Multi-objective Design and Characterization of Nanophotonic Devices

no code implementations17 May 2022 Xinyu Chen, Renjie Li, Yueyao Yu, Yuanwen Shen, Wenye Li, Zhaoyu Zhang, Yin Zhang

In this work, we propose the first-ever Transformer model (POViT) to efficiently design and simulate semiconductor photonic devices with multiple objectives.

Deep Signature FBSDE Algorithm

no code implementations24 Aug 2021 Qi Feng, Man Luo, Zhaoyu Zhang

We propose a deep signature/log-signature FBSDE algorithm to solve forward-backward stochastic differential equations (FBSDEs) with state and path dependent features.

Risk Preferences and Efficiency of Household Portfolios

no code implementations26 Oct 2020 Agostino Capponi, Zhaoyu Zhang

We propose a novel approach to infer investors' risk preferences from their portfolio choices, and then use the implied risk preferences to measure the efficiency of investment portfolios.
