Fast Online Value-Maximizing Prediction Sets with Conformal Cost Control

1 code implementation2 Feb 2023 Zhen Lin, Shubhendu Trivedi, Cao Xiao, Jimeng Sun

We focus on a typical scenario where such requirements, separately encoding $\textit{value}$ and $\textit{cost}$, compete with each other.

Conformal Prediction Intervals with Temporal Dependence

1 code implementation25 May 2022 Zhen Lin, Shubhendu Trivedi, Jimeng Sun

We focus on the task of constructing valid prediction intervals (PIs) in time series regression with a cross-section.

Taking a Step Back with KCal: Multi-Class Kernel-Based Calibration for Deep Neural Networks

no code implementations15 Feb 2022 Zhen Lin, Shubhendu Trivedi, Jimeng Sun

Most existing calibration methods either lack theoretical guarantees for producing calibrated outputs, reduce classification accuracy in the process, or only calibrate the predicted class.

SCRIB: Set-classifier with Class-specific Risk Bounds for Blackbox Models

no code implementations5 Mar 2021 Zhen Lin, Cao Xiao, Lucas Glass, M. Brandon Westover, Jimeng Sun

Despite deep learning (DL) success in classification problems, DL classifiers do not provide a sound mechanism to decide when to refrain from predicting.

DeepSZ: Identification of Sunyaev-Zel'dovich Galaxy Clusters using Deep Learning

no code implementations25 Feb 2021 Zhen Lin, Nicholas Huang, Camille Avestruz, W. L. Kimmy Wu, Shubhendu Trivedi, João Caldeira, Brian Nord

We present a comparison between two methods of cluster identification: the standard Matched Filter (MF) method in SZ cluster finding and a method using Convolutional Neural Networks (CNN).

In-Place Zero-Space Memory Protection for CNN

1 code implementation NeurIPS 2019 Hui Guan, Lin Ning, Zhen Lin, Xipeng Shen, Huiyang Zhou, Seung-Hwan Lim

Convolutional Neural Networks (CNN) are being actively explored for safety-critical applications such as autonomous vehicles and aerospace, where it is essential to ensure the reliability of inference results in the presence of possible memory faults.
