Enhancing Job Salary Prediction with Disentangled Composition Effect Modeling: A Neural Prototyping Approach

no code implementations17 Mar 2025 Yang Ji, Ying Sun, HengShu Zhu

Despite efforts on salary prediction based on job positions and talent demographics, there still lacks methods to effectively discern the set-structured skills' intricate composition effect on job salary.

Contrastive Conditional Alignment based on Label Shift Calibration for Imbalanced Domain Adaptation

1 code implementation29 Dec 2024 Xiaona Sun, Zhenyu Wu, ZhiQiang Zhan, Yang Ji

Thus, we propose contrastive conditional alignment based on label shift calibration (CCA-LSC) for IDA, to address both covariate shift and label shift.

Decoupled Federated Learning on Long-Tailed and Non-IID data with Feature Statistics

no code implementations13 Mar 2024 Zhuoxin Chen, Zhenyu Wu, Yang Ji

In the second stage, DFL-FS employs federated feature regeneration based on global feature statistics and utilizes resampling and weighted covariance to calibrate the global classifier to enhance the model's adaptability to long-tailed data distributions.

centroIDA: Cross-Domain Class Discrepancy Minimization Based on Accumulative Class-Centroids for Imbalanced Domain Adaptation

no code implementations21 Aug 2023 Xiaona Sun, Zhenyu Wu, Yichen Liu, Saier Hu, ZhiQiang Zhan, Yang Ji

Unsupervised Domain Adaptation (UDA) approaches address the covariate shift problem by minimizing the distribution discrepancy between the source and target domains, assuming that the label distribution is invariant across domains.

Dual-Branch Temperature Scaling Calibration for Long-Tailed Recognition

no code implementations16 Aug 2023 Jialin Guo, Zhenyu Wu, ZhiQiang Zhan, Yang Ji

Moreover, we noticed that the traditional calibration evaluation metric, Excepted Calibration Error (ECE), gives a higher weight to low-confidence samples in the minority classes, which leads to inaccurate evaluation of model calibration.

Multi-Factors Aware Dual-Attentional Knowledge Tracing

1 code implementation10 Aug 2021 Moyu Zhang, Xinning Zhu, Chunhong Zhang, Yang Ji, Feng Pan, Changchuan Yin

In this paper, we propose Multi-Factors Aware Dual-Attentional model (MF-DAKT) which enriches question representations and utilizes multiple factors to model students' learning progress based on a dual-attentional mechanism.

An Adaptive Oversampling Learning Method for Class-Imbalanced Fault Diagnostics and Prognostics

no code implementations19 Nov 2018 Wenfang Lin, Zhen-Yu Wu, Yang Ji

Data-driven fault diagnostics and prognostics suffers from class-imbalance problem in industrial systems and it raises challenges to common machine learning algorithms as it becomes difficult to learn the features of the minority class samples.
