Efficient Truncated Linear Regression with Unknown Noise Variance

no code implementations NeurIPS 2021 Constantinos Daskalakis, Patroklos Stefanou, Rui Yao, Emmanouil Zampetakis

In this paper, we provide the first computationally and statistically efficient estimators for truncated linear regression when the noise variance is unknown, estimating both the linear model and the variance of the noise.

A variational autoencoder approach for choice set generation and implicit perception of alternatives in choice modeling

no code implementations19 Jun 2021 Rui Yao, Shlomo Bekhor

This paper derives the generalized extreme value (GEV) model with implicit availability/perception (IAP) of alternatives and proposes a variational autoencoder (VAE) approach for choice set generation and implicit perception of alternatives.

CycleSegNet: Object Co-segmentation with Cycle Refinement and Region Correspondence

no code implementations5 Jan 2021 Chi Zhang, Guankai Li, Guosheng Lin, Qingyao Wu, Rui Yao

Image co-segmentation is an active computer vision task that aims to segment the common objects from a set of images.

PowerNet: Multi-agent Deep Reinforcement Learning for Scalable Powergrid Control

1 code implementation24 Nov 2020 Dong Chen, Kaian Chen. Zhaojian Li, Tianshu Chu, Rui Yao, Feng Qiu, Kaixiang Lin

Specifically, we consider the decentralized inverter-based secondary voltage control problem in distributed generators (DGs), which is first formulated as a cooperative multi-agent reinforcement learning (MARL) problem.
