Branching with a pre-specified finite list of -sparse split sets for binary MILPs
Santanu S. Dey, Diego Moran, Jingye Xu
When branching for binary mixed integer linear programs with disjunctions of sparsity level , we observe that there exists a finite list of -sparse disjunctions, such that an…

PPG-based Heart Rate Estimation with Efficient Sensor Sampling and Learning Models
Yuntong Zhang, Jingye Xu, Mimi Xie +4
Recent studies showed that Photoplethysmography (PPG) sensors embedded in wearable devices can estimate heart rate (HR) with high accuracy. However, despite of prior research effor…
