Closed-form dual perturb and combine for tree-based models
This paper studies the aggregation of predictions made by tree-based models for several perturbed versions of the attribute vector of a test case. A closed-form approximation of t...

Optimization via communication networks
— It has been known since the early 1990s that backpressure-type algorithms for communication networks (such as the Max-Weight algorithm) can be used to approximately solve stati...

An I/Q Channel Time-Interleaved Band-Pass Sigma-Delta Modulator for a Low-IF Receiver
—This paper proposes a multiplexing scheme to realize an I/Q channel time-interleaved (TI) band-pass sigmadelta modulator (BPSDM) that shares OTAs to minimize power consumption a...
