Stock2Vec: An Embedding to Improve Predictive Models for Companies (open access)

Stock2Vec: An Embedding to Improve Predictive Models for Companies

Building predictive models for companies often relies on inference using historical data of companies in the same industry sector. However, companies are similar across a variety of dimensions that should be leveraged in relevant prediction problems. This is particularly true for large, complex organizations which may not be well defined by a single industry and have no clear peers. To enable prediction using company information across a variety of dimensions, we create an embedding of company stocks, Stock2Vec, which can be easily added to any prediction model that applies to companies with associated stock prices. We describe the process of creating this rich vector representation from stock price fluctuations and characterize what the dimensions represent. We then conduct comprehensive experiments to evaluate this embedding in applied machine learning problems in various business contexts. Our experiment results demonstrate that the four features in the Stock2Vec embedding can readily augment existing cross-company models and enhance cross-company predictions.

For the Sake of the Song: Essays on Townes Van Zandt

Access: Use of this item is restricted to the UNT Community
After he died, Townes Van Zandt found the success that he sabotaged throughout his short life despite the release of sixteen brilliant albums. Since his death, numerous albums both by and in honor of him have been released and many critical articles published, in addition to several books (including Robert Hardy’s A Deeper Blue by UNT Press). For the Sake of the Song collects ten essays on Townes Van Zandt from a variety of approaches. Contributors examine his legacy; his use of the minor key; his reception in the Austin music scene; and an exploration of his relationship with Richard Dobson, with whom he toured as part of the Hemmer Ridge Mountain Boys. An introduction by editors Ann Norton Holbrook and Dan Beller- McKenna provides an overview of Van Zandt’s literary excellence and philosophical wisdom, rare among even the best songwriters.

[TBAAL - Dallas City Council Meeting: large debate over ]

Audio from The Black Academy of Arts and Letters of a city council meeting held on September 13. The audio begins with a prayer for patience. After, the Dallas mayor suggests moving to a different chamber to accommodate for the large number of citizen speakers in the audience and waiting outside to be seated. The discussion devolves into an argument due to a large majority of council members and audience members wanting to remain seated. Once moved, guest speakers walk up one by one to give their opinions over a tax increase on the Dallas citizens for renovations to cultural institutions such as the Dallas Convention Center and stadiums.
