Multifocal learning for customer problem analysis

Yong Ge, Hui Xiong, Wenjun Zhou, Siming Li, Ramendra Sahoo
2011 ACM Transactions on Intelligent Systems and Technology  
As a case study, we exploit multifocal learning for profiling customer problems.  ...  For instance, for the same type of problems encountered in a customer service center, the problem descriptions from different customers can be quite different.  ...  Instead, we develop a multifocal learning method for customer problem analysis in this article. Overview The rest of this article is organized as follows.  ...

Metastatic Cancer Outcome Prediction with Injective Multiple Instance Pooling [article]

Jianan Chen, Anne L. Martel
2022 arXiv   pre-print
In this paper, we process two public datasets to set up a benchmark cohort of 341 patient in total for studying outcome prediction of multifocal metastatic cancer.  ...  Although the majority of cancer deaths result from metastatic and multifocal disease, building imaging biomarkers for patients with multiple tumors has been a challenging task due to the lack of annotated  ...  We discussed the difference between the problem formulation of traditional multiple instance learning problems compared to MIL for prognosis.  ...
