Context-based Fast Recommendation Strategy for Long User Behavior Sequence in Meituan Waimai

no code implementations19 Mar 2024 Zhichao Feng, Junjiie Xie, Kaiyuan Li, Yu Qin, Pengfei Wang, Qianzhong Li, Bin Yin, Xiang Li, Wei Lin, Shangguang Wang

We first identify contexts that share similar user preferences with the target context and then locate the corresponding PoIs based on these identified contexts.

CVFC: Attention-Based Cross-View Feature Consistency for Weakly Supervised Semantic Segmentation of Pathology Images

no code implementations21 Aug 2023 Liangrui Pan, Lian Wang, Zhichao Feng, Liwen Xu, Shaoliang Peng

Specifically, CVFC is a three-branch joint framework composed of two Resnet38 and one Resnet50, and the independent branch multi-scale integrated feature map to generate a class activation map (CAM); in each branch, through down-sampling and The expansion method adjusts the size of the CAM; the middle branch projects the feature matrix to the query and key feature spaces, and generates a feature space perception matrix through the connection layer and inner product to adjust and refine the CAM of each branch; finally, through the feature consistency loss and feature cross loss to optimize the parameters of CVFC in co-training mode.

LDCSF: Local depth convolution-based Swim framework for classifying multi-label histopathology images

no code implementations21 Aug 2023 Liangrui Pan, Yutao Dou, Zhichao Feng, Liwen Xu, Shaoliang Peng

In order to be able to provide local field of view diagnostic results, we propose the LDCSF model, which consists of a Swin transformer module, a local depth convolution (LDC) module, a feature reconstruction (FR) module, and a ResNet module.

PACS: Prediction and analysis of cancer subtypes from multi-omics data based on a multi-head attention mechanism model

no code implementations21 Aug 2023 Liangrui Pan, Dazheng Liu, Zhichao Feng, Wenjuan Liu, Shaoliang Peng

Due to the high heterogeneity and clinical characteristics of cancer, there are significant differences in multi-omic data and clinical characteristics among different cancer subtypes.

DEDUCE: Multi-head attention decoupled contrastive learning to discover cancer subtypes based on multi-omics data

1 code implementation9 Jul 2023 Liangrui Pan, Dazhen Liu, Yutao Dou, Lian Wang, Zhichao Feng, Pengfei Rong, Liwen Xu, Shaoliang Peng

In this study, we proposed a generalization framework based on attention mechanisms for unsupervised contrastive learning to analyze cancer multi-omics data for the identification and characterization of cancer subtypes.
