Proceedings ArticleDOI
Sentiment classification based on supervised latent n-gram analysis
TL;DR: A deep neural network is utilized to build a unified discriminative framework that allows for estimating the parameters of the latent space as well as the classification function with a bias for the target classification task at hand.
Proceedings ArticleDOI
Reeb graph based shape retrieval for cad
TL;DR: This work adopts a method of comparing solid models based on Multiresolutional Reeb graphs (MRG) similarity computations, and shows the performance of the Reeb Graph technique when handling primitive CAD models, and discusses the technique’s performance on complex CAD models.
Journal ArticleDOI
Local feature extraction and matching partial objects
TL;DR: This paper shows how a Scale–Space technique can extract features that are invariant with respect to the global structure of the model as well as small perturbations that 3D laser scanning process introduce, and introduces a new distance function defined on triangles instead of points.
Proceedings ArticleDOI
Scale-space representation of 3D models and topological matching
TL;DR: A framework for shape matching through scale-space decomposition of 3D models through spectral decomposition is presented, based on recent developments in efficient hierarchical decomposing of metric data using its spectral properties.
Proceedings ArticleDOI
Benchmarking CAD search techniques
TL;DR: This study reveals the strengths and weaknesses of existing research in these areas, introduces open challenge problems, and provides meaningful datasets and metrics against which the success of current and future work can be measured.
