Query Optimization Properties of Modified VBS

arXiv.org Artificial Intelligence

Valuation-Based System can represent knowledge in different domains including probability theory, Dempster-Shafer theory and possibility theory. More recent studies show that the framework of VBS is also appropriate for representing and solving Bayesian decision problems and optimization problems. In this paper after introducing the valuation based system (VBS) framework, we present Markov-like properties of VBS and a method for resolving queries to VBS. 1 Introduction Though graphical representation of a domain knowledge has quite long history, its full potential has not been recognized until recently. We should mention here pioneering works of J. Pearl, reported in his monography published in 1988 [ 1988] . Further development in this domain has been achieved by Shenoy and Shafer [ 1986 ] who adopted a method used in solving nonserial dynamic programming problems [ Bertele & Brioschi, 1972 ] . This trick proved to be very fruitful and gave growth to a unified framework for uncertainty representation and reasoning, called V aluation-Based System, VBS for short [ Shenoy, 1989 ] .


Search Engine Founder says Artificial Intelligence cannot be created

Every day, there is a new report, news item, scientific publication where some company or the other, some research team, some start up claims to have launched a product built with Artificial Intelligence, or to have achieved a breakthrough in this field, or promises a new product which will change the entire field. Unfortunately, the term Artificial Intelligence or AI for short, has to be the most over abused term by scientists, computer programmers, start up entrepreneurs and the tech media alike. It is still in close competition with the term Big Data, though. My name is Sukhbir Benipal and i am the founder and creator of the e commerce search engine benipal.com, I have been working in this field for over 5 years and tried endlessly, at various points even believing i had a breakthrough, until one day when Hurricane Sandy hit Manhattan, and with no power, heat or running hot water, finally realizing i was so wrong, on all counts.


Optimal query complexity for private sequential learning

arXiv.org Machine Learning

Motivated by privacy concerns in many practical applications such as Federated Learning, we study a stylized private sequential learning problem: a learner tries to estimate an unknown scalar value, by sequentially querying an external database and receiving binary responses; meanwhile, a third-party adversary observes the learner's queries but not the responses. The learner's goal is to design a querying strategy with the minimum number of queries (optimal query complexity) so that she can accurately estimate the true value, while the adversary even with the complete knowledge of her querying strategy cannot. Prior work has obtained both upper and lower bounds on the optimal query complexity, however, these upper and lower bounds have a large gap in general. In this paper, we construct new querying strategies and prove almost matching upper and lower bounds, providing a complete characterization of the optimal query complexity as a function of the estimation accuracy and the desired levels of privacy.


8 Timeless Job Search Strategies to Beat AI

#artificialintelligence

Despite all the talk about how A.I. is taking over industries, pushing people out of jobs, and reshaping the hiring process, I'm here to tell you that as long as "human" remains a central element of "human resources," you can rely on a few surefire job search tactics that reach people. Many career analysts and insiders claim the resume is dead, but you have permission to ignore them at least for one more year. Many companies still use screening technologies that hinge on parsing resumes, so a well-written, keyword-rich document is crucial to your career. You should also read their excellent articles. Read Jon Shields article where he offers 56 resume tips to guide you through the process.


CodeSearchNet Challenge: Evaluating the State of Semantic Code Search

arXiv.org Machine Learning

Semantic code search is the task of retrieving relevant code given a natural language query. While related to other information retrieval tasks, it requires bridging the gap between the language used in code (often abbreviated and highly technical) and natural language more suitable to describe vague concepts and ideas. To enable evaluation of progress on code search, we are releasing the CodeSearchNet Corpus and are presenting the CodeSearchNet Challenge, which consists of 99 natural language queries with about 4k expert relevance annotations of likely results from CodeSearchNet Corpus. The corpus contains about 6 million functions from open-source code spanning six programming languages (Go, Java, JavaScript, PHP, Python, and Ruby). The CodeSearchNet Corpus also contains automatically generated query-like natural language for 2 million functions, obtained from mechanically scraping and preprocessing associated function documentation. In this article, we describe the methodology used to obtain the corpus and expert labels, as well as a number of simple baseline solutions for the task. We hope that CodeSearchNet Challenge encourages researchers and practitioners to study this interesting task further and will host a competition and leaderboard to track the progress on the challenge. We are also keen on extending \task to more queries and programming languages in the future.


Dependency-based Text Graphs for Keyphrase and Summary Extraction with Applications to Interactive Content Retrieval

arXiv.org Artificial Intelligence

We build a bridge between neural network-based machine learning and graph-based natural language processing and introduce a unified approach to keyphrase, summary and relation extraction by aggregating dependency graphs from links provided by a deep-learning based dependency parser. We reorganize dependency graphs to focus on the most relevant content elements of a sentence, integrate sentence identifiers as graph nodes and after ranking the graph, we extract our keyphrases and summaries from its largest strongly-connected component. We take advantage of the implicit structural information that dependency links bring to extract subject-verb-object, is-a and part-of relations. We put it all together into a proof-of-concept dialog engine that specializes the text graph with respect to a query and reveals interactively the document's most relevant content elements. The open-source code of the integrated system is available at https:// github.com/ptarau/DeepRank .

Yes, you can add JSON structured data to the body of your pages - Search Engine Land

#artificialintelligence

JSON structured data can be inserted in the head as well as the body of your pages, Webmaster Trends Analyst John Mueller explained on the September 11 edition of #AskGoogleWebmasters. "Is it possible to insert JSON structured data at the bottom of the body instead of the head? It seems to work fine for many websites," asked user @largow via Twitter. Yes, you can insert JSON structured data either in the body or the head. Mueller also took this opportunity to explain the three structured data formats that Google supports. Rich results aren't going anywhere, so it's on SEOs to adapt their efforts to the search results page.


Job Search Strategies in the Age of Automation and Artificial Intelligence

#artificialintelligence

Recent technological advancements have brought improvements to the recruitment process. It has changed the sourcing, reviewing, and consideration of job candidates. Now, employers don't need to go through dozens of resumes to find top talent. Sometimes, open posts are not advertised publicly. Therefore, you must know the technologies that are used in recruitment today when you are job seeking.
