Cellpose: a generalist algorithm for cellular segmentation
Nature Methods, 2020 Many biological applications require the segmentation of cell bodies, membranes and nuclei from microscopy images. Deep learning has enabled great progress on this problem, but current methods are specialized for images that have large training datasets.

On the Segmentation of Markets [PDF]
Journal of Political Economy, 2007 This paper endogenizes the market structure of an economy with heterogeneous agents who want to form bilateral matches in the presence of search frictions and when utility is nontransferable. There exist infinitely many marketplaces, and each agent chooses which marketplace to be in: agents get to choose not only whom to match with but also whom they ...

Text Segmentation by Cross Segment Attention [PDF]
Proceedings of the 2020 Conference on Empirical Methods in Natural Language Processing (EMNLP), 2020 Document and discourse segmentation are two fundamental NLP tasks pertaining to breaking up text into constituents, which are commonly used to help downstream tasks such as information retrieval or text summarization. In this work, we propose three transformer-based architectures and provide comprehensive comparisons with previously proposed approaches

Rich Feature Hierarchies for Accurate Object Detection and Semantic Segmentation [PDF]
2014 IEEE Conference on Computer Vision and Pattern Recognition, 2013 Object detection performance, as measured on the canonical PASCAL VOC dataset, has plateaued in the last few years. The best-performing methods are complex ensemble systems that typically combine multiple low-level image features with high-level context.

Segmentation by transduction [PDF]
2008 IEEE Conference on Computer Vision and Pattern Recognition, 2008 This paper addresses the problem of segmenting an image into regions consistent with user-supplied seeds (e.g., a sparse set of broad brush strokes). We view this task as a statistical transductive inference, in which some pixels are already associated with given zones and the remaining ones need to be classified.

Segmentation-Aware Convolutional Networks Using Local Attention Masks [PDF]
, 2017 We introduce an approach to integrate segmentation information within a convolutional neural network (CNN). This counter-acts the tendency of CNNs to smooth information across regions and increases their spatial precision.

Segmentation of multiple retailers’ clients on the basis of shopping occasions
Business: Theory and Practice, 2006 Rapid development of a retailing sector and the emergence of multiple retailers (also called chain stores or chains of stores) significantly increased the power of retailers over other members of products distribution channels.

Segmentation of Discrete Curves into Fuzzy Segments
Electronic Notes in Discrete Mathematics, 2003 A new concept, fuzzy segments, is introduced which allows for flexible segmentation of discrete curves, so taking into account some noise in them. Relying on an arithmetic approach of discrete straight lines, it generalizes them, admitting that some points are missing. Thus, a larger class of objects is considered.
