Understanding Job-Skill Relationships Using Big Data and Neural Networks
Understanding Job-Skill Relationships using Big Data and Neural Networks Abhinav Maurya Carnegie Mellon University Pittsburgh, PA – 15213 [email protected] ABSTRACT Our proposed model is inspired by topic modeling where Nonlinear vector space embeddings have shown great promise latent topics occur throughout the documents of a corpus in many applications such as similarity search, analogy map- in varying proportions, which enables their identification to pings, dataset visualization, etc. In this paper, we propose characterize the text corpus. Similarly, in our model, vari- a simple distribution-to-distribution regression model based ation in the co-occurrence of jobs and skills can be used on neural networks which provides (i) job2vec: interpretable to disentangle which skills are associated with which jobs. embeddings of jobs in terms of associated skills, (ii) skill2vec: However, unlike unsupervised topic models such as LDA [1], converse embeddings of skills in terms of the jobs that re- we cast our problem of identifying job-skill associations as quire them, and (iii) SkillRank: a mechanism for ranking a supervised distribution-to-distribution regression, where skills associated with each job that can be recommended the input is the empirical distribution over job titles and to members aspiring for that job.

If you notice discrepancies between this document and the version of Eclipse/MyEclipse you are using to perform the install that make it difficult or impossible to follow this guide, please see the User Feedback section on how to report the issue. Back to Top 2. Introduction In this tutorial we will be walking through a small JSF demo application using MyEclipse Enterprise Workbench. Previous knowledge of JSF and/or MyEclipse is not necessary, but would be helpful. Since Struts is such a prevalent web application framework, similarities between JSF and Struts will be noted, where appropriate, to help the reader with previous Struts experience. However, if you have no prior experience with Struts, you may feel free to skip these sections . Back to Top 3.

Survey of Verification and Validation Techniques for Small Satellite Software Development
Survey of Verification and Validation Techniques for Small Satellite Software Development Stephen A. Jacklin NASA Ames Research Center Presented at the 2015 Space Tech Expo Conference May 19-21, Long Beach, CA Summary The purpose of this paper is to provide an overview of the current trends and practices in small-satellite software verification and validation. This document is not intended to promote a specific software assurance method. Rather, it seeks to present an unbiased survey of software assurance methods used to verify and validate small satellite software and to make mention of the benefits and value of each approach. These methods include simulation and testing, verification and validation with model-based design, formal methods, and fault-tolerant software design with run-time monitoring. Although the literature reveals that simulation and testing has by far the longest legacy, model-based design methods are proving to be useful for software verification and validation. Some work in formal methods, though not widely used for any satellites, may offer new ways to improve small satellite software verification and validation. These methods need to be further advanced to deal with the state explosion problem and to make them more usable by small-satellite software engineers to be regularly applied to software verification. Last, it is explained how run-time monitoring, combined with fault-tolerant software design methods, provides an important means to detect and correct software errors that escape the verification process or those errors that are produced after launch through the effects of ionizing radiation. Introduction While the space industry has developed very good methods for verifying and validating software for large communication satellites over the last 50 years, such methods are also very expensive and require large development budgets. -
