We will discuss the nature of play, how play in the preschool pre-structures habits of mind that are required by creative adults, and how these precursors can be supported by the sensitive parent or teacher. The talk will be divided into two hours: the first hour can be an exposition of ideas, the second can be a dialogue with the audience. We can prepare the participants with advanced provocat...

Enjoying amazing ancient structures through Internet technologies is one of the most promising methods to promote our culture and cultural heritage. These technologies involve sensing, transmission, and display. In this talk, I will briefly explain these three aspects, and then focus on sensing issues, in particular, the technical challenges presented by sensing huge outdoor structures. I will ...

Our aim is to present a personal view of Gdel's incompleteness. We will focus on interesting/natural concrete independent sentences, on the source of incompleteness, and on how common the incompleteness phenomenon is. Some open questions will be briefly stated. Speaker: Cristian Calude A lifelong researcher in algorithmic information theory and a close friend of Gregory Chaitin, Dr. Calude has ...

In knowledge-based information retrieval, search engines consult external sources of knowledge ontologies, taxonomies, thesauri, glossaries, gazeteers to help process the documents they encounter and the requests they receive. The idea is old, obvious, and compelling but results have been singularly unimpressive. The best performing and most widely used search systems are still those that deal ...

To evaluate an innovation in computer systems, performance analysts measure execution time or other metrics using one or more standard workloads. The performance analyst may carefully minimize the amount of measurement instrumentation, control the environment in which measurement takes place, and repeat each measurement multiple times. Finally, the performance analyst may use statistical techni...

This is the first Annual Cornell University Faculty of Computing and Information Science (CIS)/Cornell Silicon Valley (CSV) event in Silicon Valley. It will feature the Dean of CIS, Robert Constable, along with Cornell alumnus (and Googler) Amit Singhal. Speaker: Robert Constable Speaker: Amit Singhal Google Tech Talks September 19, 2008

Berners-Lee's vision of the Semantic Web is hindered by a chicken-and-egg problem, which can be best solved by a bootstrapping method: creating enough structured data to motivate the development of applications. We believe that autonomously `Semantifying Wikipedia' is the best way to bootstrap. We choose Wikipedia as an initial data source, because it is comprehensive, high-quality, modestly si...

Discovery of frequent patterns = finding positive conjunctions that are true for a given fraction of the observations - this basic idea can be instantiated in many ways: - finding frequent sets from 0/1 data (association mining) - finding frequent episodes in sequences - finding frequent subgraphs in graphs etc. - efficient algorithms exist -- the levelwise approach - theoretical analysis of th...

1 - "Patterns in sets of points: an overview" "We illustrate the importance of optimization principles in the search for interesting patterns, more in particular for patterns in sets of points embedded in a metric space. This talk will be a journey along the types of patterns in point sets that can efficiently be searched for, and general principles will be outlined. We provide examples from di...
