IBM developerWorks: Learning PHP (Part
2) 06/22/2005 02:48 AM
The IBM developerWorks site has posted their second in the series of "Learning PHP" tutorails.

This tutorial is Part 2 of a three-part series that takes you from the most basic PHP script to working with databases and streaming from the file system by documenting the building of a document workflow system. Here, documents are uploaded by users and stored in a non-Web-accessible location for retrieval by the application in Part 3. We also look at working with XML files using DOM and SAX, and we look at exceptions.

They don't mess around with their introductions to PHP, jumping right into a document management script, complete with a look at working with XML...

In a comment, Kevin Jordan writes: 348North News is a normal aggregator in much of the way you think of it. However, it allows me to identify keywords or themes that it puts together into phrases — and then matches up the phrases with like articles. Like a cross between Google News and Daypop (but that makes it sound much more complex than it is). If you want to see an "interests" based summary for me, check out the Phrase Index. I use fairly general keywords so as not to miss out on the future items. I haven't tried...

Working with Bayesian categorizers

Working with Bayesian categorizers 12/02/2003 01:38 AM

There's been some discussion in the blog world about using a Bayesian categorizer to enable a person to discriminate along various interest/non-interest axes. I took a run at this recently and, although my experiments haven't been wildly successful, I want to report them because I think the idea may have merit. [Full story: O'Reilly Network: Working with Bayesian Categorizers]

This month's O'Reilly Network column was a struggle because categorization itself is a struggle. I remain convinced that the automated classifiers that are doing such a good job beating back the tide of spam will also turn out to be more generally useful. But finding the right synergy between an automated assistant and a human overseer is a subtle and tricky thing. ...

Subconsciously, People may be Bayesian

Subconsciously, People may be Bayesian 01/22/2004 02:48 AM
DAVID LEONHARDT writes in a NY Times article about people playing the odds of everyday life with Bayesian Analysis. He describes new research, recently published in Nature, "which stands out because it offers a detailed window into how the Bayesian thought process works, showing the point when uncertainty becomes great enough to give past experience an edge over current observation." Bayesian Analysis, among researchers, is "the combining of new information with conventional wisdom." I do agree about their reliance on past observations, but I believe that they have underestimated the role of future orientation in the whole mix of decision making.

Bayesian spam filtering for the masses

Bayesian spam filtering for the masses 10/30/2003 11:59 PM
Spam, or unsolicited commercial e-mail, is now a sad part of everyday life online. Research companies estimate that more than 50% of the worldwide e-mail traffic is spam. As a result, it's becoming constantly more difficult and time-consuming to sort out legitimate e-mails from the deluge of commercial messages we're being flooded with. But there are ways to fight back. In this series, we'll walk through choosing and setting up a highly effective package for screening out spam.

Bayesian anti-spam filters count word-frequency in suspect and compare the results to profiles of word-frequency in spam and ham. Defeating this requires that your spam include a lot of natural human prose. So spammers have started to mine the Gutenberg Project and other sources of human-generated ASCII and dumping random hunks of literature into their messages to get around the filters.

Blogger and journalist Clive Thompson found an excerpt from Chapter 20 of The Master Key by Wizard of Oz author L Frank Baum in a message that had as its subject line "the big unit" (no prizes for guessing what the rest of it was hawking).

Bayesian statistical modelling is a tool used to compare new events to past experience, something useful for applications as diverse as predicting whether a message is spam and whether a Web-page is relevant to a given subject. New research indicates that we do a lot of Bayesian comparisons in our heads, particularily when engaged in athletic tasks:

"Most decisions in our lives are done in the presence of uncertainty," Dr. Körding said. "In all these cases, the prior knowledge we have can be very helpful. If the brain works in the Bayesian way, it would optimally use the prior knowledge."

The researchers drew the analogy to tennis in their paper, and it is not the first study to suggest that athletes have a more sophisticated understanding of mathematics than even they may realize.

Bayesian spam rumination: when

Bayesian spam rumination: when
word-frequency-histograms attack! 06/29/2004 10:40 AM
Ed Felten has posted an intriguing rumination on the possible failure modes of Bayesian spam-filtering -- filtering that uses word-frequency statistics to classify email as spam or ham. As Ed points out, Bayesian filters are trained by the spammers, who, by choosing the vocabulary of their messages carefully, can make messages containing certain words or phrases undeliverable on the Internet.

Now suppose a big spammer wanted to poison a particular word, so that messages containing that word would be (mis)classified as spam. The spammer could sprinkle the target word throughout the word salad in his outgoing spam messages. When users classified those messages as spam, the targeted word would develop a negative score in the users' Bayesian spam filters. Later, messages with the targeted word would likely be mistaken for spam.

This attack could even be carried out against a particular targeted user. By feeding that user a steady diet of spam (or pseudo-spam) containing the target word, a malicious person could build up a highly negative score for that word in the targeted user's filter.

John Lautner's Chemosphere: part
Jetsons, part Bond and vintage L.A.
Modern. 04/07/2005 12:53 PM
The most modern home built in the world. "From the outside it looks like a spaceship you cannot enter. But if you go inside, it feels very cozy… very Zen and calming. Maybe because you are floating above the city, in the sky". John Lautner's Chemosphere residence is the product of a fortuitous union of architect, client, time and place. Leonard Malin was a young aerospace engineer in late-1950s L.A. whose father-in-law had just given him a plot north of Mulholland Drive, near Laurel Canyon. The only catch: at roughly 45 degrees, the slope was all but unbuildable. Lautner sketched a bold vertical line, a cross, and a curve above it. "Draw it up," he told his assistant. Now publisher Benedik t Taschen owns Chemosphere (NSFW), and after 20 years of neglect the house has been beautifully restored (.pdf) by Frank Escher.
