Swivel: Improving Embeddings by Noticing What's Missing
We present Submatrix-wise Vector Embedding Learner (Swivel), a method for generating lowdimensional feature embeddings from a feature co-occurrence matrix. Swivel performs approximate factorization of the point-wise mutual information matrix via stochastic gradient descent. It uses a piecewise loss with special handling for unobserved co-occurrences, and thus makes use of all the information in...
متن کاملHuman kinetochores are swivel joints that mediate microtubule attachments
Chromosome segregation is a mechanical process that requires assembly of the mitotic spindle - a dynamic microtubule-based force-generating machine. Connections to this spindle are mediated by sister kinetochore pairs, that form dynamic end-on attachments to microtubules emanating from opposite spindle poles. This bi-orientation generates forces that have been reported to stretch the kinetochor...
متن کاملExcited state properties of oligophenyl and oligothienyl swivel cruciforms.
A comprehensive study has been undertaken of the electronic spectral and photophysical properties of two oligophenyl (BPH and BPHF) and one oligothienyl (BTF) swivel cruciforms involving measurements of absorption, fluorescence, and phosphorescence spectra, quantum yields of fluorescence (phiF), phosphorescence (phiPh) and triplet formation (phiT), lifetimes of fluorescence (tauF) and of the tr...
متن کاملTo Fork or Not to Fork: Fork Motivations in SourceForge Projects
A project fork occurs when software developers take a copy of source code from one software package and use it to begin an independent development work that is maintained separately. Although forking in open source software does not require the permission of the original authors, the new version competes for the attention of the same developers that have worked on the original version. The moti...
متن کاملA small swivel joint for infusion of free moving animals.
construction and application of a small, light, inexpensive swivel joint suitable for infusions of small laboratory animals is described. Commercially available tubes and needles are used in the construction of the swivel thus making it easy to prepare and essentially disposable. This swivel is especially useful in long-and short-term infusions of pharmaca and nutrients in the general circulati...
