Towards Entity Alignment in the Open World: An Unsupervised Approach

2021 · arXiv (Cornell University)

Entity alignment (EA) aims to discover the equivalent entities in different knowledge graphs (KGs). It is a pivotal step for integrating KGs to increase knowledge coverage and quality. Recent years have witnessed a rapid increase …

A Data-driven Neural Network Used on Maneuvering Target Tracking

2023

Maneuvering target tracking is a key issue in the field of target tracking. The target tracking based on the motion model is hard to accurately predict and track maneuvering target. This article design a data-driven …

An SMT Formalization of Mixed-Precision Matrix Multiplication: Modeling Three Generations of Tensor Cores

2025 · arXiv (Cornell University)

Many recent computational accelerators provide non-standard (e.g., reduced precision) arithmetic operations to enhance performance for floating-point matrix multiplication. Unfortunately, the properties of these accelerators are not widely understood and lack sufficient descriptions of their behavior. …

Machine Learning Applications for Fraud Detection and Financial Sentiment

2025

This review examines machine learning applications in two major financial tasks: fraud detection and financial sentiment analysis. For fraud detection, research demonstrates that ensemble models, particularly gradient boosting methods such as CatBoost, XGBoost, and LightGBM, …

Robust Dual-Stream Diagnosis Network for Ultrasound Breast Tumor Classification with Cross-Domain Segmentation Priors

2026 · Sensors

Ultrasound imaging is widely used for early breast cancer screening to enhance patient survival. However, interpreting these images is inherently challenging due to speckle noise, low lesion-to-tissue contrast, and highly variable tumor morphology within complex …
