Realised Volatility Forecasting: Machine Learning via Financial Word Embedding [PDF]

open access: yesSocial Science Research Network, 2021
We develop FinText, a novel, state-of-the-art, financial word embedding from Dow Jones Newswires Text News Feed Database. Incorporating this word embedding in a machine learning model produces a substantial increase in volatility forecasting performance ...

Track Layouts of Graphs [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2004
A \emph(k,t)-track layout of a graph G consists of a (proper) vertex t-colouring of G, a total order of each vertex colour class, and a (non-proper) edge k-colouring such that between each pair of colour classes no two monochromatic edges cross.

Stacks, Queues and Tracks: Layouts of Graph Subdivisions [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2005
A \emphk-stack layout (respectively, \emphk-queuelayout) of a graph consists of a total order of the vertices, and a partition of the edges into k sets of non-crossing (non-nested) edges with respect to the vertex ordering.

On Linear Layouts of Graphs [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2004
In a total order of the vertices of a graph, two edges with no endpoint in common can be \emphcrossing, \emphnested, or \emphdisjoint. A \emphk-stack (respectively, \emphk-queue, \emphk-arch) \emphlayout of a graph consists of a total order of the ...

Upward Partitioned Book Embeddings [PDF]

open access: yes, 2018
We analyze a directed variation of the book embedding problem when the page partition is prespecified and the nodes on the spine must be in topological order (upward book embedding). Given a directed acyclic graph and a partition of its edges into $k$ pages, can we linearly order the vertices such that the drawing is upward (a topological sort) and ...

Follow the Pathfinders: a Case Study Approach to Production, Use, and Readership on Scalar

open access: yesHyperrhiz, 2021
This born-digital article examines the multimodal academic publication Pathfinders (Moulthrop and Grigar). Through a combination of interviews with readers and the author, textual analysis of the book, and literature review of Scalar, I trace the ...

Implementing a Partitioned 2-Page Book Embedding Testing Algorithm [PDF]

open access: yesInternational Symposium Graph Drawing and Network Visualization, 2012
In a book embedding the vertices of a graph are placed on the "spine" of a "book" and the edges are assigned to "pages" so that edges on the same page do not cross.

Steganography via E-Books With the EPUB Format by Rearrangements of the Contents of the CSS Files

open access: yesIEEE Access, 2020
With the advance of information technology and mobile devices, e-book reading has become a popular way for people to gain knowledge. However, with the widespread uses of digital texts, issues about the copyright protection of e-books have arisen.

Research on Recommendation Algorithm of Joint Light Graph Convolution Network and DropEdge

open access: yesJournal of Advanced Transportation, 2022
Overfitting in a deep neural network leads to low recommendation precision and high loss. To mitigate these issues in a deep neural network-based recommendation algorithm, we propose a recommendation algorithm, LG-DropEdge, joint light graph ...
