Linear Span Network for Object Skeleton Detection [PDF]
Lecture Notes in Computer Science, 2018 Robust object skeleton detection requires to explore rich representative visual features and effective feature fusion strategies. In this paper, we first re-visit the implementation of HED, the essential principle of which can be ideally described with a linear reconstruction model.

Minimum linear span approximation of binary sequences
IEEE Transactions on Information Theory, 2002 Summary: The determination of the minimum linear span sequence that differs from a given binary sequence, of period \(N=2^n-1\), by at most one digit is discussed and three methods are presented: the sequential divisions method, the congruential equations method, and the phase synchronization method.

Velocity of magnetic holes in the solar wind from Cluster multipoint measurements [PDF]
Annales Geophysicae, 2023 We present the first statistical study on the velocity of magnetic holes (MHs) in the solar wind. Magnetic holes are localized depressions of the magnetic field, often divided into two classes: rotational and linear MHs.

A Span-based Linearization for Constituent Trees [PDF]
Proceedings of the 58th Annual Meeting of the Association for Computational Linguistics, 2020 We propose a novel linearization of a constituent tree, together with a new locally normalized model. For each split point in a sentence, our model computes the normalizer on all spans ending with that split point, and then predicts a tree span from them. Compared with global models, our model is fast and parallelizable.

Contributions of meteorology and anthropogenic emissions to the trends in winter PM2.5 in eastern China 2013–2018 [PDF]
Atmospheric Chemistry and Physics, 2022 Multiple linear regression (MLR) models are used to assess the contributions of meteorology/climate and anthropogenic emission control to linear trends of PM2.5 concentration during the period 2013–2018 in three regions in eastern China, namely Beijing ...
