An Improved Convolutional Neural Network Algorithm for Multi-Label Classification

2018

Recent years conventional neural network(CNN) has been applied to different natural language processing(NLP) tasks such as sentence classification, sentence modeling, etc. Some researchers use CNN to do multi-label classification but their work mainly focus on …

One Vertex Attack on Graph Neural Networks-based Spatiotemporal Forecasting

2021

Spatiotemporal forecasting plays an essential role in intelligent transportation systems (ITS) and numerous applications, such as route planning, navigation, and automatic driving. Deep Spatiotemporal Graph Neural Networks, which capture both spatial and temporal patterns, have …

Secretary Bird Escape Strategy-Guided Dynamic PID Search Algorithm

2025

The PID Search Algorithm (PSA) is an effective optimization method but suffers from limited global search capability, often leading to premature convergence. To address these limitations, this paper proposes the Secretary Bird Escape Strategy-Guided Dynamic …
