Large Covariance Matrix Estimation With Nonnegative Correlations

AISTATS 2025poster

Covariance matrix estimation is a fundamental problem in multivariate data analysis. In many situations, it is often observed that variables exhibit a positive linear dependency, indicating a positive linear correlation. This paper tackles the challenge of estimating covariance matrices with positi…

Adaptive Quantization with Mixed-Precision Based on Low-Cost Proxy

Junzhe Chen, Qiao Yang, Senmao Tian, Shunli Zhang

ICASSP 2024accepted

It is critical to deploy complicated neural network models on hardware with limited resources. This paper proposes a novel model quantization method, named the Low-Cost Proxy-Based Adaptive Mixed-Precision Model Quantization (LCPAQ), which contains three key modules. The hardware-aware module is des…
