论文摘要

多型对象多视图多实体多标签学习(M4L)处理由不同实例制成的互连的多型对象(或袋子),这些实例具有不同的特征视图,并带有一组非判有性但具有语义上相关的标签的注释。 M4L比典型的多视图多标签多标签学习(M3L)更一般和强大,该学习只能容纳单身袋,并且缺乏能够在物理世界中自然相互连接的多类型物体共同建模的力量。为了应对这项新颖而充满挑战的学习任务,我们开发了基于矩阵分解的解决方案(M4L-JMF)。特别是,M4L-JMF首先将多型袋子之间的多种属性和多个属性(内部)交配编码为各自的数据矩阵,然后将这些矩阵共同将这些矩阵分配到低级别的矩阵中,以探索每个袋子及其实例及其实例的复合潜伏表示(如果有)。此外,它还包含一个调度和聚合项,以将袋子的标签分配给各个实例,并以连贯的方式将实例的标签相反。基准数据集上的实验结果表明,M4L-JMF比现有M3L溶液在此新问题上的简单适应取得的结果明显好得多。

Multi-typed objects Multi-view Multi-instance Multi-label Learning (M4L) deals with interconnected multi-typed objects (or bags) that are made of diverse instances, represented with heterogeneous feature views and annotated with a set of non-exclusive but semantically related labels. M4L is more general and powerful than the typical Multi-view Multi-instance Multi-label Learning (M3L), which only accommodates single-typed bags and lacks the power to jointly model the naturally interconnected multi-typed objects in the physical world. To combat with this novel and challenging learning task, we develop a joint matrix factorization based solution (M4L-JMF). Particularly, M4L-JMF firstly encodes the diverse attributes and multiple inter(intra)-associations among multi-typed bags into respective data matrices, and then jointly factorizes these matrices into low-rank ones to explore the composite latent representation of each bag and its instances (if any). In addition, it incorporates a dispatch and aggregation term to distribute the labels of bags to individual instances and reversely aggregate the labels of instances to their affiliated bags in a coherent manner. Experimental results on benchmark datasets show that M4L-JMF achieves significantly better results than simple adaptions of existing M3L solutions on this novel problem.
