MLGCN: An Ultra Efficient Graph Convolution Neural Model For 3D Point Cloud Analysis

no code implementations31 Mar 2023 Mohammad Khodadad, Morteza Rezanejad, Ali Shiraee Kasmaee, Kaleem Siddiqi, Dirk Walther, Hamidreza Mahyar

To address these limitations we introduce a novel Multi-level Graph Convolution Neural (MLGCN) model, which uses Graph Neural Networks (GNN) blocks to extract features from 3D point clouds at specific locality levels.

The Logical Difference for the Lightweight Description Logic EL

no code implementations23 Jan 2014 Boris Konev, Michel Ludwig, Dirk Walther, Frank Wolter

In all three cases, we present polynomial-time algorithms that decide whether two terminologies give the same answers to queries over a given vocabulary and compute a succinct representation of the difference if it is non- empty.

Reasoning About the Transfer of Control

no code implementations16 Jan 2014 Wiebe van der Hoek, Dirk Walther, Michael Wooldridge

The logical foundation of DCL-PC is CL-PC, a logic for reasoning about cooperation in which the abilities of agents and coalitions of agents stem from a distribution of atomic Boolean variables to individual agents -- the choices available to a coalition correspond to assignments to the variables the coalition controls.

Exploring Functional Connectivities of the Human Brain using Multivariate Information Analysis

no code implementations NeurIPS 2009 Barry Chai, Dirk Walther, Diane Beck, Li Fei-Fei

In this study, we present a method for estimating the mutual information for a localized pattern of fMRI data.

Hierarchical Mixture of Classification Experts Uncovers Interactions between Brain Regions

no code implementations NeurIPS 2009 Bangpeng Yao, Dirk Walther, Diane Beck, Li Fei-Fei

In this paper, we propose to model such connections in an Hidden Conditional Random Field (HCRF) framework, where the classifier of one region of interest (ROI) makes predictions based on not only its voxels but also the classifier predictions from ROIs that it connects to.
