Use neural networks to recognize students' handwritten letters and incorrect symbols

no code implementations12 Sep 2023 Jiajun Zhu, Zichuan Yang, Binjie Hong, Jiacheng Song, Jiwei Wang, Tianhao Chen, Shuilan Yang, Zixun Lan, Fei Ma

Correcting students' multiple-choice answers is a repetitive and mechanical task that can be considered an image multi-classification task.


RCsearcher: Reaction Center Identification in Retrosynthesis via Deep Q-Learning

no code implementations28 Jan 2023 Zixun Lan, Zuo Zeng, Binjie Hong, Zhenfu Liu, Fei Ma

The critical insight in this framework is that the single or multiple reaction center must be a node-induced subgraph of the molecular product graph.

More Interpretable Graph Similarity Computation via Maximum Common Subgraph Inference

no code implementations9 Aug 2022 Zixun Lan, Binjie Hong, Ye Ma, Fei Ma

Our critical insight into INFMCS is the strong correlation between similarity score and Maximum Common Subgraph (MCS).

Sub-GMN: The Neural Subgraph Matching Network Model

no code implementations1 Apr 2021 Zixun Lan, Limin Yu, Linglong Yuan, Zili Wu, Qiang Niu, Fei Ma

Comparing with the previous GNNs-based methods for subgraph matching task, our proposed Sub-GMN allows varying query and data graphes in the test/application stage, while most previous GNNs-based methods can only find a matched subgraph in the data graph during the test/application for the same query graph used in the training stage.
