Deep Multi-instance Networks with Sparse Label Assignment for Whole Mammogram Classification

1 code implementation23 May 2017 Wentao Zhu, Qi Lou, Yeeleng Scott Vang, Xiaohui Xie

Inspired by the success of using deep convolutional features for natural image analysis and multi-instance learning (MIL) for labeling a set of instances/patches, we propose end-to-end trained deep multi-instance networks for mass classification based on whole mammogram without the aforementioned ROIs.

Deep Multi-instance Networks with Sparse Label Assignment for Whole Mammogram Classification

no code implementations18 Dec 2016 Wentao Zhu, Qi Lou, Yeeleng Scott Vang, Xiaohui Xie

Inspired by the success of using deep convolutional features for natural image analysis and multi-instance learning for labeling a set of instances/patches, we propose end-to-end trained deep multi-instance networks for mass classification based on whole mammogram without the aforementioned costly need to annotate the training data.

Novelty Detection Under Multi-Instance Multi-Label Framework

no code implementations25 Nov 2013 Qi Lou, Raviv Raich, Forrest Briggs, Xiaoli Z. Fern

Contrary to the common assumption in MIML that each instance in a bag belongs to one of the known classes, in novelty detection, we focus on the scenario where bags may contain novel-class instances.
