Characterizing the impact of geometric properties of word embeddings on task performance

Analysis of word embedding properties to inform their use in downstream NLP tasks has largely been studied by assessing nearest neighbors. However, geometric properties of the continuous feature space contribute directly to the use of embedding features in downstream models, and are largely unexplored. We consider four properties of word embedding geometry, namely: position relative to the origin, distribution of features in the vector space, global pairwise distances, and local pairwise distances. We define a sequence of transformations to generate new embeddings that expose subsets of these properties to downstream models and evaluate change in task performance to understand the contribution of each property to NLP models. We transform publicly available pretrained embeddings from three popular toolkits (word2vec, GloVe, and FastText) and evaluate on a variety of intrinsic tasks, which model linguistic information in the vector space, and extrinsic tasks, which use vectors as input to machine learning models. We find that intrinsic evaluations are highly sensitive to absolute position, while extrinsic tasks rely primarily on local similarity. Our findings suggest that future embedding models and post-processing techniques should focus primarily on similarity to nearby points in vector space.Comment: Appearing in the Third Workshop on Evaluating Vector Space Representations for NLP (RepEval 2019). 7 pages + reference

Can the Health Needs of African American Men Be Met Through Public Health Empowerment Strategies?

Health promotion and disease prevention efforts, which use empowerment strategies and emphasize community control, are essential to overcoming the legacy of medical malfeasance and successfully improving the health status of black males. This discussion depicts the legacy of harm and presents the case for empowerment strategies; it also describes one Boston community-based program example of utilizing an empowerment strategy and concludes with a challenge to all health professionals to become enablers of empowerment rather than obstructions to it

Counternarratives from Women of Color Academics: Bravery, Vulnerablility and Resistance

This book documents the lived experiences of women of color academics who have leveraged their professional positions to challenge the status quo in their scholarship, teaching, service, activism, and leadership. By presenting reflexive work from various vantage points within and outside of the academy, contributors document the cultivation of mentoring relationships, the use of administrative roles to challenge institutional leadership, and more. Through an emphasis on the various ways in which women of color have succeeded in the academy—albeit with setbacks along the way—this volume aims to change the discourse surrounding women of color academics: from a focus on trauma and mere survival to a focus on courage and thriving.https://scholarship.richmond.edu/bookshelf/1311/thumbnail.jp

Digital design using selection operations

A digital integrated circuit chip is designed by identifying a logical structure to be implemented. This logical structure is represented in terms of a logical operations, at least 5% of which include selection operations. A determination is made of logic cells that correspond to an implementation of these logical operations

Digital logic optimization using selection operators

According to the invention, a digital design method for manipulating a digital circuit netlist is disclosed. In one step, a first netlist is loaded. The first netlist is comprised of first basic cells that are comprised of first kernel cells. The first netlist is manipulated to create a second netlist. The second netlist is comprised of second basic cells that are comprised of second kernel cells. A percentage of the first and second kernel cells are selection circuits. There is less chip area consumed in the second basic cells than in the first basic cells. The second netlist is stored. In various embodiments, the percentage could be 2% or more, 5% or more, 10% or more, 20% or more, 30% or more, or 40% or more

Reverse vortex flow in near-surface explosions

Nuclear explosions conducted near the ground surface but higher than about 5 to 6 m/kt/sup 1/3/ produce a reverse flow (downward along the symmetry axis) after the shock wave is reflected from the ground. This reverse flow persists until destroyed by the buoyant rise of the fireball on time scales of several seconds. Six calculations of bursts with scaled heights-of-burst ranging upward from 15 m/kt/sup 1/3/ are described. The height of the reverse flow is a simple function of the burst height and explosion yield

Digital circuits using universal logic gates

According to the invention, a digital circuit design embodied in at least one of a structural netlist, a behavioral netlist, a hardware description language netlist, a full-custom ASIC, a semi-custom ASIC, an IP core, an integrated circuit, a hybrid of chips, one or more masks, a FPGA, and a circuit card assembly is disclosed. The digital circuit design includes first and second sub-circuits. The first sub-circuits comprise a first percentage of the digital circuit design and the second sub-circuits comprise a second percentage of the digital circuit design. Each of the second sub-circuits is substantially comprised of one or more kernel circuits. The kernel circuits are comprised of selection circuits. The second percentage is at least 5%. In various embodiments, the second percentage could be at least 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, or 95%

Voter Identification Requirements: Background and Legal Issues

Since 2008, more than 30 states have enacted laws relating to voter identification, with several containing photo ID requirements. Several states enacted voter identification laws that have either been struck down by courts or are not yet in effect. A number of bills with voter identification provisions have been introduced in the 113th Congress and one (S. 1945) has received committee consideration. This report examines this type of legislation and the legal issues regarding it
