Boosting Ant Colony Optimization via Solution Prediction and Machine Learning

2020 · arXiv (Cornell University)

This paper introduces an enhanced meta-heuristic (ML-ACO) that combines machine learning (ML) and ant colony optimization (ACO) to solve combinatorial optimization problems. To illustrate the underlying mechanism of our ML-ACO algorithm, we start by describing …

Robust One-Shot Segmentation of Brain Tissues via Image-Aligned Style Transformation

2023 · Proceedings of the AAAI Conference on Artificial Intelligence

One-shot segmentation of brain tissues is typically a dual-model iterative learning: a registration model (reg-model) warps a carefully-labeled atlas onto unlabeled images to initialize their pseudo masks for training a segmentation model (seg-model); the seg-model …

SST: Semantic and Structural Transformers for Hierarchy-aware Language Models in E-commerce

2023

Hierarchies are common structures used to organize data, such as e-commerce hierarchies associated with product data. With these product hierarchies, we aim to learn hierarchy-aware product text embeddings to improve fine-tuning performance on a variety …
