The You Factor

via Dilbert.com Blog:

My previous post got one of the top ratings for anything I've blogged about. Several of you wondered if I saw the recent episode of Penn and Teller's Bullsh*t that apparently dealt with the "cold read" phenomenon, in which general statements seem more personal than they are. I missed that ... [-->]

You should read this.

Keyworddichte: relevante SEO-Basics oder vernachlaessigbare Vergangenheit?

via SEO-Blog - SISTRIX GmbH:

An der Keyworddichte als Rankingfaktor scheiden sich die Geister: für die einen ist sie ein Blick zurück auf den Anfang dieses Jahrtausends als häufiges Wiederholen des Keywords im Text und Dateinamen einen bei Fireball wirklich weit nach vorne brachte, für die anderen ist der prozentuale Anteil, de ... [-->]

Interessant - hätte nicht gedacht, dass die Termfrequenz noch einen so grossen Einfluss hat.

Going Mini: Extreme Lightweight Spam Filters

Nice result. I wonder if it's really necessary to train only on the top features. Why not train on all features and then select the top weigths for a smaller model? If the goal is only to be able to store all models in memory, that should be enough.

Haha, sehr schön - Film@11. Klingt gar nicht so absurd, wie die ganzen "Rettet unser obsoletes Geschäftsmodell!"-Aufrufe von heute.

Speed Matters

via Google Research Blog - (Research Admin):

Posted by Jake Brutlag, Web Search Infrastructure

At Google, we've gathered hard data to reinforce our intuition that "speed matters" on the Internet. Google runs experiments on the s ... [-->]

The surprising fact for me is, that slowness has so little impact on usage. I would have expected that it's much more important. Maybe this is because google owns a quasi-monopole on websearch... waiting 400ms for a search request seems pretty much unacceptable for me.
