When he mapped this data\, he was able to discover where flu outbreaks would strike up to two weeks before tra ditional news sources were able to report them. http://www.google.org/fl utrends/ \;\n \;\nThis is an example of a time when merging a spec ific type of data to its geographical coordinates resulted in a unique i nsight. However\, there is much more to do with data and visualization. What was found at Google is only the tip of a very large iceberg. Now th at we have access to so much data on the web\, we're going to see an inc reasing need to understand and present that data. \;\n \;\nAgenda : \;\nThis meetup will serve as an introduction to what's going on in the world of data viz. It will be freeform\, so if you would like to de monstrate something you're working on\, please be prepared to do so. Mic ah Elliott will be showing uGraph and Ed Borasky will do a GGobi demo. I 'll be covering what already exists in the ecosystem and what might beco me useful in the future. We're dealing with a rapid communication method here. Something that\, if done well\, compresses the time and space it takes for us to understand something. \;\n \;\nIf you're interest ed in Data Visualization\, please come to this event. It will be the fir st Portland Tech Event at WebTrends besides Web Analytics Wednesday. It' s our chance to try out the space and see if it is a good fit for this g roup or potentially for other groups in the future. \;\n \;\nGoog le Group: \;\nEd Borasky recently started a Google group called pdx- visualization. As the name implies\, it is a group for Portland-area peo ple interested in languages and techniques for visualization of data. ht tp://groups.google.com/group/pdx-visualization \;\n \;\n------ \;\n \;\nAmber Case\, @caseorganic is a Cyborg Anthropologist studyin g the interaction between humans and computers and how our relationship with information is changing the way we think\, act\, and understand the world around us. \;\n\n\nTags: data visualization\, technology\, po rtland tech\, trending\, analytics\, analysis\n\nImported from: http://c alagator.org/events/1250456781 URL:http://groups.google.com/group/pdx-visualization SUMMARY:Portland Data Visualization Group LOCATION:Webtrends: 851 SW 6th Ave.\, Suite 1600\, Portland OR 97204 US SEQUENCE:0 END:VEVENT BEGIN:VEVENT CREATED;VALUE=DATE-TIME:20090324T211525Z DTEND;TZID=America/Los_Angeles;VALUE=DATE-TIME:20090328T150000 DTSTART;TZID=America/Los_Angeles;VALUE=DATE-TIME:20090328T110000 DTSTAMP;VALUE=DATE-TIME:20090324T211525Z LAST-MODIFIED;VALUE=DATE-TIME:20090324T231356Z UID:http://calagator.org/events/1250456875 DESCRIPTION:R\, also called GNU S\, is a strongly functional language and environment to statistically explore data sets and make many graphical displays of data. \;\n \;\nR is widely used for statistical softw are development and data analysis. R is part of the GNU project\, and it s source code is freely available under the GNU General Public License\, and pre-compiled binary versions are provided for various operating sys tems. R uses a command line interface\, though several graphical user in terfaces are available. \;\n \;\nEd Borasky will provide an introd uction to R this Saturday at Cubespace from 11Am-3Pm. Please come prepar ed with a laptop and the requisite software (link to come soon). If you have any issues installing the software\, or need help before the meetin g\, feel free to arrive at 10:30 Am. \;\n \;\nSoftware Downloads& #13\;\nUpdated to get ready for the upcoming class.

Problems of this type abound in areas as diverse as computational biology\, multimedia indexing\, and anomaly detection. Evaluating the p erformance of a binary labeling algorithm is itself a complex task\, oft en based on a domain-dependent notion of the relative cost of "\;fal se positives"\; versus "\;false negatives"\;. As these costs are often not available to researchers or engineers\, a number of metho ds are used to provide a cost-independent analysis of performance. In th is talk\, I will examine a number of these methods both theoretically an d experimentally. The presented results suggest a set of best practices for evaluating binary classification algorithms\, while questioning whet her a cost-independent analysis is even possible. \n\nTags: galois\, ana lysis\, tech talk\, algorithms\n\nImported from: http://calagator.org/ev ents/1250462359 URL:http://corp.galois.com/blog/2012/5/4/tech-talk-an-analysis-of-analysi s.html SUMMARY:Galois Tech Talk: An Analysis of Analysis LOCATION:Galois\, Inc: 421 SW 6th Ave. Suite 300\, Portland OR 97204 US SEQUENCE:1 END:VEVENT BEGIN:VEVENT CREATED;VALUE=DATE-TIME:20120725T171413Z DTEND;TZID=America/Los_Angeles;VALUE=DATE-TIME:20120802T113000 DTSTART;TZID=America/Los_Angeles;VALUE=DATE-TIME:20120802T103000 DTSTAMP;VALUE=DATE-TIME:20120725T171413Z LAST-MODIFIED;VALUE=DATE-TIME:20120725T171413Z UID:http://calagator.org/events/1250462652 DESCRIPTION:Presented by Iulian Neamtiu. \;\n \;\nThe relative nove lty and rapid evolution pace of the Android ecosystem (platform\, vendor -installed apps and third-party apps) means both the platform and apps r eceive little scrutiny. Hence there is a need for tools that assess\, mo nitor and verify all components of the Android ecosystem. This lack of t ools and scrutiny is particularly problematic when combined with the ope n nature of Google Play\, the main app distribution channel. \;\n \;\nIn the first part of this talk we will focus on multi-layer profilin g of Android apps using ProfileDroid\, a tool and framework we developed at UC Riverside. ProfileDroid is useful for a variety of Android app an alyses\, from performance to usability to security. ProfileDroid monitor s and correlates the behavior of an app at four layers: (a) static\, or app specification (b) user interaction\, (c) operating system\, and (d) network layer. Using ProfileDroid on 27 free and paid Android apps\, we have revealed: (a) discrepancies between the app specification and app e xecution\, (b) free versions of apps could end up costing more than thei r paid counterparts\, due to an order of magnitude increase in traffic\, (c) most network traffic is not encrypted\, (d) apps communicate with m any more sources than users might expect. \;\n \;\nIn the second p art of the talk we will present results from our long-term permission ev olution study of the Android ecosystem---platform and 237 apps---over th ree years. We found that the platform has increased the number of danger ous permissions and does not move towards finer-grained permissions\, an d that app developers do not follow the principle of least privilege. We will also briefly discuss our efforts with static information flow trac king for Android apps\, as well as building a log-and-replay system for Android.\n\nTags: security\, galois\, mobile\, android\, analysis\, tech talk\n\nImported from: http://calagator.org/events/1250462652 URL:http://corp.galois.com/blog/2012/7/25/tech-talk-comprehensive-analysi s-of-the-android-ecosystem.html SUMMARY:Galois Tech Talk: Comprehensive Analysis of the Android Ecosystem LOCATION:Galois\, Inc: 421 SW 6th Ave. Suite 300\, Portland OR 97204 US SEQUENCE:1 END:VEVENT BEGIN:VEVENT CREATED;VALUE=DATE-TIME:20140106T233250Z DTEND;TZID=America/Los_Angeles;VALUE=DATE-TIME:20140121T210000 DTSTART;TZID=America/Los_Angeles;VALUE=DATE-TIME:20140121T183000 DTSTAMP;VALUE=DATE-TIME:20140106T233250Z LAST-MODIFIED;VALUE=DATE-TIME:20140106T233250Z UID:http://calagator.org/events/1250465440 DESCRIPTION:Yes\, Hacks/Hackers PDX is still alive!
