FinerPCN: High fidelity point cloud completion network using pointwise convolution

Neurocomputing, 2021
Abstract 3D scanners often obtain partial point clouds due to occlusion and limitation of viewing angles. Point cloud completion aims at inferring the full shape of an object from an incomplete point set. Existing deep learning models either do not consider local information or easily degrade the sharp details of the input, thereby losing some ...

Pointwise topology on completely distributive lattices

Fuzzy Sets and Systems, 1989
In the recent years the fuzzy topology has developed considerably. Since all fuzzy sets on a non-empty set form a lattice, the fuzzy topology is a topology on a lattice. Now the author generalizes the theory of fuzzy topology to a theory of pointwise topology on complete, completely distributive lattices.

Pointwise Logic on Completely Distributive Lattices and Approximate Reasoning

2008 Fifth International Conference on Fuzzy Systems and Knowledge Discovery, 2008
In this paper, we propose the basic framework of point- wise topological logic on completely distributive lattices and explore approximate reasoning in it. The logic of this paper is based on pointwise characterization, therefore the pointwise conception is pervasive.

Complete Characterizations of Global Optimality for Problems Involving the Pointwise Minimum of Sublinear Functions

SIAM Journal on Optimization, 1996
Summary: Necessary and sufficient global optimality conditions are presented for certain non-convex minimization problems subject to inequality constraints that are expressed as the pointwise minimum and sublinear (MSL) functions. A generalized Farkas lemma for inequality systems with MSL functions plays a crucial role in presenting the conditions in ...

The Dedekind Completion of C(X) with Pointwise Discontinuous Functions

2016
In this paper we show that whenever X is a topological space, which is completely regular and Baire, then the Dedekind completion of C(X), the space of all real continuous functions on X, is the Dedekind complete Riesz space of all pointwise discontinuous functions, where two functions that coincides on a dense set are identified.
