Knowledge Distillation on Spatial-Temporal Graph Convolutional Network for Traffic Prediction

no code implementations22 Jan 2024 Mohammad Izadi, Mehran Safayani, Abdolreza Mirzaei

Recognizing the significance of timely prediction due to the dynamic nature of real-time data, we employ knowledge distillation (KD) as a solution to enhance the execution time of ST-GNNs for traffic prediction.

HDGL: A hierarchical dynamic graph representation learning model for brain disorder classification

no code implementations6 Nov 2023 Parniyan Jalali, Mehran Safayani

The human brain can be considered as complex networks, composed of various regions that continuously exchange their information with each other, forming the brain network graph, from which nodes and edges are extracted using resting-state functional magnetic resonance imaging (rs-fMRI).

Joint Sentiment/Topic Modeling on Text Data Using Boosted Restricted Boltzmann Machine

no code implementations10 Nov 2017 Masoud Fatemi, Mehran Safayani

By modifying the structure of RBM as well as appending a layer which is analogous to sentiment of text data to it, we propose a generative structure for joint sentiment topic modeling based on neutral networks.
