  title={Negative-Unlabeled Tensor Factorization for Location Category Inference from Inaccurate Mobility Data},
  author={Jinfeng Yi and Qi Lei and Wesley M. Gifford and Ji Liu},
Identifying significant location categories visited by mobile users is the key to a variety of applications. This is an extremely challenging task due to the possible deviation between the estimated location coordinate and the actual location, which could be on the order of kilometers. To estimate the actual location category more precisely, we propose a novel tensor factorization framework, through several key observations including the intrinsic correlations between users, to infer the most… Expand

Modeling User Activity Preference by Leveraging User Spatial Temporal Characteristics in LBSNs
A STAP model is proposed that first models the spatial and temporal activity preference separately, and then uses a principle way to combine them for preference inference, and a context-aware fusion framework is put forward to combine the temporal and spatial activity preference models for preferences inference.

Learning from Partial Labels
This work proposes a convex learning formulation based on minimization of a loss function appropriate for the partial label setting, and analyzes the conditions under which this loss function is asymptotically consistent, as well as its generalization and transductive performance. Expand
Mining user similarity based on location history
A framework, referred to as hierarchical-graph-based similarity measurement (HGSM), is proposed for geographic information systems to consistently model each individual's location history and effectively measure the similarity among users and outperforms related similarity measures, such as the cosine similarity and Pearson similarity measures.

PU Learning for Matrix Completion
This paper considers the matrix completion problem when the observations are one-bit measurements of some underlying matrix M, and in particular the observed samples consist only of ones and no zeros, and proposes a "shifted matrix completion" method that recovers M using only a subset of indices corresponding to ones.

Provable Tensor Factorization with Missing Data
A novel alternating minimization based method which iteratively refines estimates of the singular vectors which can recover a three-mode n × n → n dimensional rank-r tensor exactly from O(n3/2r5 log4 n) randomly sampled entries. Expand
Finding similar users using category-based location history
The approach first models a user's GPS trajectories with a semantic location history (SLH) and measures the similarity between different users' SLHs by using the maximal travel match (MTM) algorithm, which outperforms the related works. Expand
