Adaptive Local Low-rank Matrix Approximation for Recommendation

Huafeng Liu, Liping Jing, Yuhua Qian, Jian Yu

Low-rank matrix approximation (LRMA) has attracted more and more attention in the community of recommendation. Even though LRMA-based recommendation methods (including Global LRMA and Local LRMA) obtain promising results, ...

Intuitionistic fuzzy rough set-based granular structures and attribute subset selection

Anhui Tan, Weizhi Wu, Yuhua Qian, Jiye Liang, Jinkun Chen, Jinjin Li

Attribute subset selection is an important issue in dataminingandinformationprocessing.However,mostautomatic methodologies consider only the relevance factor between samples while ignoring the diversity factor. This may not allow the utilization value of hidden information to be exploited. For this reason, we propose a hybrid model named intuitionistic fuzzy (IF) rough set to overcome this limitation. The model combines the technical advantages of rough set and IF set and can effectively consider the above-mentioned statistical factors.

Clustering ensemble based on sample's stability

Feijiang Li, Yuhua Qian, Jieting Wang, Chuangyin Dang, Liping Jing

The objective of clustering ensemble is to fifind the underlying structure of data based on a set of clustering results. It has been observed that the samples can change between clusters in different clustering results. This change shows that samples may have different contributions to the detection of the underlying structure.

Environmental sound classification with dilated convolutions

In sound information retrieval (SIR) area, environmental sound classification (ESC) emerges as a new issue, which aims at classifying environments by analysing the complex features extracted from the various sound data.
