Online Semi-supervised Learning with Mix-Typed Streaming Features
2023 · Proceedings of the AAAI Conference on Artificial Intelligence
Online learning with feature spaces that are not fixed but can vary over time renders a seemingly flexible learning paradigm thus has drawn much attention. Unfortunately, two restrictions prohibit a ubiquitous application of this learning …

OR-AutoRec: An Outlier-Resilient Autoencoder-based Recommendation model
2022
Deep neural network (DNN) is widely adopted to develop the recommender systems (RSs) in recent years due to its powerful non-linear representation learning ability. So far, various sophisticated DNN-based RSs have been achieved to provide …

A Latent Factor Analysis-Based Approach to Online Sparse Streaming Feature Selection
2021 · IEEE Transactions on Systems Man and Cybernetics Systems
Online streaming feature selection (OSFS) has attracted extensive attention during the past decades. Current approaches commonly assume that the feature space of fixed data instances dynamically increases without any missing data. However, this assumption does …
