En-Compactness: Self-Distillation Embedding & Contrastive Generation for Generalized Zero-Shot Learning

Computer Vision and Pattern Recognition, 2022
Generalized zero-shot learning (GZSL) requires a classifier trained on seen classes that can recognize objects from both seen and unseen classes. Due to the absence of unseen training samples, the classifier tends to bias towards seen classes.

Compaction

2023
Soil compaction is a decrease in pore space driven by mechanical stresses. It is prevalent in agriculture, forestry and construction due to too high wheel loads by machinery, leading to adverse impacts to drainage, aeration and soil strength that affects plants and exchanges between soils and the wider environment.

Separability and Compactness Network for Image Recognition and Superresolution

IEEE Transactions on Neural Networks and Learning Systems, 2019
Convolutional neural networks (CNNs) have wide applications in pattern recognition and image processing. Despite recent advances, much remains to be done for CNNs to learn a better representation of image samples. Therefore, constant optimizations should

Compact groups of compact galaxies. V

Astrophysics, 1976
The lists of compact groups of compact galaxies are continued with a third list, which contains 54 new objects of this class discovered at Byurakan on the Palomar Sky Survey Charts. Searches were made in the +60, +66, +72/sup 0/ zones of the charts, which were completely surveyed except for regions near the galactic equator.

Compactness and Local Compactness

2011
The cover definition of compactness is basically point-free; therefore there is no surprise that the basic facts are very much like in the classical case. But a surprise does come: the point-free variant of Stone-?Cech compactification is fully constructive (no choice principle and no use of the excluded middle).

Hilbert compacts, compact ellipsoids, and compact extrema

Journal of Mathematical Sciences, 2010
We consider a system of so-called Hilbert compacts K(H) in a Hilbert space H; those Hilbert compacts admit a two-sided estimate by compact ellipsoids in H. For functionals in H, we introduce the notion of a compact extremum achieved at a certain base with respect to the imbedding in K(H).

Concentration-compactness principle for Trudinger–Moser inequalities on Heisenberg groups and existence of ground state solutions

, 2017
Let $$\mathbb {H}^{n}=\mathbb {C}^{n}\times \mathbb {R}$$Hn=Cn×R be the n-dimensional Heisenberg group, $$Q=2n+2$$Q=2n+2 be the homogeneous dimension of $$\mathbb {H}^{n}$$Hn. We extend the well-known concentration-compactness principle on finite domains

Compactness properties of locally compact groups

Transformation Groups, 1997
For a discrete group \(\Gamma\) and an integer \(n\), finiteness properties \(FP_n\) and \(F_n\) are considered. They are defined as follows: \(\Gamma\) is of type \(FP_n\) if there is a projective resolution of \(\mathbb{Z} \Gamma\) over the trivial \(\mathbb{Z} \Gamma\)-module \(\mathbb{Z}\) with finitely generated modules in dimension \(\leq n\). \(\

Compaction behavior of roller compacted ibuprofen

European Journal of Pharmaceutics and Biopharmaceutics, 2008
The effect of roller compaction pressure on the bulk compaction of roller compacted ibuprofen was investigated using instrumented rotary tablet press. Three different roller pressures were utilized to prepare granules and Heckel analysis, Walker analysis, compressibility, and tabletability were performed to derive densification, deformation, course of ...
