Utilizing Semantic Textual Similarity for Clinical Survey Data Feature Selection

1 code implementation19 Aug 2023 Benjamin C. Warner, Ziqi Xu, Simon Haroutounian, Thomas Kannampallil, Chenyang Lu

A relatively unexplored source of information in the feature selection process is the usage of textual names of features, which may be semantically indicative of which features are relevant to a target outcome.

Self-Supervised Road Layout Parsing with Graph Auto-Encoding

1 code implementation21 Mar 2022 Chenyang Lu, Gijs Dubbelman

Aiming for higher-level scene understanding, this work presents a neural network approach that takes a road-layout map in bird's-eye-view as input, and predicts a human-interpretable graph that represents the road's topological layout.

Real-Time Edge Classification: Optimal Offloading under Token Bucket Constraints

1 code implementation26 Oct 2020 Ayan Chakrabarti, Roch Guérin, Chenyang Lu, Jiangnan Liu

To deploy machine learning-based algorithms for real-time applications with strict latency constraints, we consider an edge-computing setting where a subset of inputs are offloaded to the edge for processing by an accurate but resource-intensive model, and the rest are processed only by a less-accurate model on the device itself.
