 Posted: Thu Aug 30, 2012 5:13 am Post subject: CPU Project of the Month Sep. 2012=> Distributed Data Min |
 |
|
By one of the widest vote margins ever, our CPU Project of the Month is Distributed Data Mining. I suspect a big attraction is it has a new application related to evolution.
| Quote: | Multi-Agent Simulation of Evolution
In this project we investigate the biological phenomenon of aposematism (also referred to as warning coloration). This term describes the evolutionary strategy of certain animal species to indicate their unpalatability/toxicity to potential predators by developing skin colors and patterns that can be easily perceived by them. Prominent examples of toxic animals with distinct warning coloration are poison dart frogs, coral snakes and fire salamanders.
The evolution of aposematism has intrigued many biologists, because at first glance, an evolutionary paradox seems to be underlying: Why would unpalatable prey animals acquire conspicious warning coloration if this trait makes them more likely to be spotted and eaten by predators? Given that aposematism can be frequently observed in the animal world, the question arises how these warning signals could have evolved so many times despite their apparent evolutionary disadvantage. The paradox is even aggravated by the fact that in its inital stage of evolution, the proposed benefit of aposematic colors (i.e. making it easier for predators to learn the prey’s unpalatability) cannot be present. Consequently, the evolution of aposematism has spurred more than a century of scientific discussion and investigation; it has been addressed both experimentally and theoretically.
For tackling this interesting research challenge, we developed a distributed multi-agent model that simulates the dynamic interactions of predator and prey populations over time. By systematically testing different adaptation and learning strategies for the agents and exploring the parameter space of our simulation model using the computational power of the dDM project, we might be able to deepen the understanding of the aposematism phenomenon and the evolutionary paths leading to it.

And the throat video analysis project is also running.
| Quote: | Laryngeal high-speed video classification
For the clinical diagnosis of pathological conditions of the human body a variety of sophisticated examination techniques are employed these days. Most of these approaches yield vast amounts of images and measurement data with high spatial and/or temporal resolutions, e.g. MRI, CT, and Ultrasound. In order to reliably evaluate these data for diagnostic purposes, a certain extent of subjective experience is required on the part of the physician. Due to different reasons, in usual clinical time frames the amount of time available for analyzing and interpreting the acquired data is limited. As a result, diagnostic failure may occur, which can have serious consequences for the affected patient. By means of combined image processing and data analysis approaches this crucial diagnostic process can be objectified and automated. Thus, Computer-Aided Diagnosis systems can be provided to the physician, facilitating her/his clinical decision and yielding more reliable identification of pathological alterations.
One particular field of interest within this medical context is the automatic identification of voice disorders, resulting in perceivable hoarseness. Commonly, for this purpose audio recordings of the acoustical voice signal are analyzed with specialized software quantifying the amount of perturbation (noise) in the signal. However, this type of acoustical analysis does not allow for the clear assignment of certain clinical pictures to a distinct set of perturbation parameters. A more revealing approach for voice diagnosis consists in endoscopic examination of the sound-producing vocal folds in the larynx by means of digital high-speed cameras. These cameras are capable of recording the laryngeal movements at a frame rate of several thousand images per second, and thus, allowing for conclusive real-time analysis. However, the task of manually analyzing the resulting high-speed videos is time-consuming and error-prone. Through automated feature extraction from the recordings and subsequent machine learning analysis, laryngeal movement patterns can be quantitatively captured and automatically classified according to different diagnostic classes (e.g. organic and functional dysphonia). By means of the distributedDataMining infrastructure, we evaluated a large number of machine learning paradigms (e.g. Support Vector Machines, Artificial Neural Networks) and corresponding parameter optimization strategies (e.g. Grid search, Evolution strategy, Genetic algorithms). This preliminary evaluation step allowed us to identify certain learning schemes and parameters which are particularly suited for the considered clinical classification task.

| Quote: | Oracle Quietly Releases 'Emergency' Java Patch
Oracle has released a new version of Java to address the serious security flaws that attackers have been exploiting all week. Users are encouraged to immediately apply the latest Java update to close the zero-day vulnerabilities in the Java Runtime Environment, Oracle said in its advisory on Thursday.
If exploited, these security holes allow attackers to download and execute arbitrary code on victim computers. Researchers have identified two flaws in JRE 1.7 which attackers were chaining together to push the Poison Ivy Remote Access Tool (RAT) onto victims.

Well since DDM relies on Java, you might use the above excuse to update to the latest version.
Er' well now maybe not......
| Quote: | Researchers Find Critical Vulnerability in Java 7 Patch Hours After Release
Security researchers from Poland-based security firm Security Explorations claim to have discovered a vulnerability in the Java 7 security update released Thursday that can be exploited to escape the Java sandbox and execute arbitrary code on the underlying system.
Security Explorations sent a report about the vulnerability to Oracle on Friday together with a proof-of-concept exploit, Adam Gowdiak, the security company's founder and CEO said Friday via email. The company doesn't plan to release any technical details about the vulnerability publicly until Oracle addresses it, Gowdiak said.
Oracle broke out of its regular four-month patching cycle on Thursday to release Java 7 Update 7, an emergency security update that addressed three vulnerabilities, including two that were being exploited by attackers to infect computers with malware since last week. Java 7 Update 7 also patched a "security-in-depth issue" which, according to Oracle, was not directly exploitable, but could have been used to aggravate the impact of other vulnerabilities.

Not many knights shrubbing this PoTM.

Java issues seem to have worked themselves out on my end. Running DDM at full sprint now

We are really running slow against B@P. Of course they have over 3 times as many people running the project than we do.
| Code: | 1 BOINC@Poland 130 53,452 12,796,075
2 The Knights Who Say Ni! 39 17,797 21,304,849 |
Can we get a little more heat, please?

I can add a little something next week, but I'm busy with Simap atm. Sici is sorta kneck in kneck, and the challenge is on  Someone's already biting their nails from what he says, hoping we beat Sici this go around also

thx, though the challenge is between SETI.USA and Sicituradastra on the monthly SIMAP challenge. They're trying to win the #1 spot, and we're trying to make sure it doesn't happen
Their output has dropped recently, but the question for everyone is if they're bunkering a bit to drop at the end

I'll be back as soon as the Simap scramble is over, another 18 hrs.

Production is up from about 7K daily average to 37K average in the past week. Need more, we've done better...

OK, my main rig is pretty much done with SIMAP, I can throw a little something on here, though I'll probably end up giving GPU tasks more then 1 core and all going ahead Well, after I clean out some GPU tasks I was running instead of POEM to have more cores available for the challenge...

OK then, when they're server doesn't time out on BOINC trying to communicate with it...

I did try running DDM but just had some issues running the WUs maybe next month.

Do you have the appropriate current Java installed, 32 or 64bit?

In order for DDM to run you must install 32 bit java even if you are running a 64 bit system. The apps use the 32 bit version
