Trustworthy Preference Completion in Social Choice [article]

Lei Li, Minghe Xue, Huanhuan Chen, Xindong Wu
2020 arXiv   pre-print
Therefore, a certain common voting rule for the first k trustworthy neighboring agents based on certainty and conflict can be taken to conduct the trustworthy preference completion.  ...  Hence, in this paper firstly, a trust-based anchor-kNN algorithm is proposed to find k-nearest trustworthy neighbors of the agent with trust-oriented Kendall-Tau distances, which will handle the cases  ...  Traditionally, in neighborhood-based preference completion, it is first to find the near neighbors of each agent and then aggregate these neighbors' rankings to produce the predicted preference [13] .  ...

Near-Regular Texture Synthesis by Random Sampling and Gap Filling [article]

Diego Lopez Recas, Anna Hilsmann, Peter Eisert
2011 International Symposium on Vision, Modeling, and Visualization  
In this paper, we propose a method which we call Random Sampling and Gap Filling (RSGF) to synthesize near-regular textures.  ...  Results presented in this paper show that our method does not only produce convincing results for regular or near-regular textures but also for irregular textures.  ...  In this paper, we propose a method to synthesize nearregular textures in a constrained random sampling approach.  ...

Finding Crucial Subproblems to Focus Global Search

On certain classes of structured problems, such search outperforms traditional heuristics by at least an order of magnitude in both time and space.  ...  If, however, one could predict crucial subproblems (the portions of a constraint satisfaction problem likely to cause each other particular difficulty) in advance, search could address them first.  ...  This work was supported in part by NSF IIS-0328743, PSC-CUNY, and Science Foundation Ireland under Grant 00/PI.1/C075.  ...

2018 arXiv   pre-print
Surprisingly, in spite of its centrality, there has been an active debate under which conditions RRT is probabilistically complete.  ...  For the kinodynamic case with forward propagation of random controls and duration, we only consider in addition mild Lipschitz-continuity conditions.  ...  which expands the nearest neighbor to a random sample point.  ...
