Regularization in intrinsically sparse networks
My study (with a set of computational experiments) on the role of regularization in learning the network topology in a relatively novel neuroevolutionary scheme for intrinsically sparse networks:

Firefox vs. Chrome
The newer versions of Mozilla Firefox (currently 7.0.1) seem to be deteriorating (under Windows 7). It becomes unresponsive more and more often, even with relatively few tabs. And it seems that other people complain as well, and that Firefox is gradually getting more broken.

So I've tried Chrome again (I did not like it when I tried it quite a while ago), and it seems to be much better and faster now. It also has equivalents of the two add-ons I like and depend on: TooManyTabs (the same name and maker as for Firefox, although the interface is quite different), and ToCyrillic (instead of RussKey for Firefox).

So it looks like I am migrating. It seems that many others are migrating to Chrome as well, mostly from Explorer, but also from Firefox:

Synchronicity
Прочитал вчера Бориса Стругацкого, "Бессильные мира сего", там есть довольно неположительный герой, Гриша-Ядозуб.

Сегодня гуляю по аризонским горам и вижу... настоящего ядозуба! Раньше я их видел только в неволе -- а тут он был прямо на тропинке, очень близко, уполз неохотно. Да ещё и оказалось, что он -- Шломо! (Почему их называют Gila -- известно, а вот почему Shlomo -- я не знаю.)

"Matter is mind hide-bound with habit"
A quote by C.S.Peirce.

I have not realized that he was a panpsychist. The most natural (although not the only) interpretation of this quote is that awareness is universal, and that matter comes as a result of "particles of mind" forming patterns due to "habit". I like this model.

После Белой книги
Три стандартные книжки MIT-шных студентов-алгоритмистов:

Rajeev Motwani, Prabhakar Raghavan. Randomized Algorithms. Cambridge University Press, 1995.

Vijay Vazirani. Approximation Algorithms. Springer, 2003.

Eugene Lawler. Combinatorial Optimization: Networks and Matroids. Dover paperback reprint of 1976 edition.

Довольно старые книжки для таких динамичных областей.

Weight control: a successful experiment
I was running an experiment since the New Year trying my own custom slow weight-loss method (with the idea of reversing a slow weight-gain long term trend, and achieving a slow weight-loss long term trend). I finally achieved the milestone I've set to myself 5 months ago (going down back to the local minimum reached in September 2008 by losing 12 pounds).

I had a nice guilt-free technique which worked for me for smoking control (a high voluntary per-cigarette "tax"), but I could not figure out how to apply that to food.

However, it turns out that there is a very simple method: do not consume calories in the evening (say, after 6pm; it makes sense to allow a couple of "grace days" a week, otherwise weight loss might be too steep and unhealthy, and one doesn't want that, and one also wants to have some penalty-free and guilt-free wiggle room). This restriction is so simple, that it is easy to self-impose a voluntary "tax" scheme for breaking this rule. The "tax" should be affordable, but sufficiently high to induce some reluctance to break the constraint.

The details should probably be tuned individually, but if someone wants to know how I tuned it for myself, I'll tell you privately.

Memorial Day smoke
Бостон и окрестности (включая Кэйп Код) наполнены дымом, вроде бы, от канадских пожаров, пахнет гарью.

http://wbztv.com/local/cape.cod.smoke.2.1724527.html



Смогом это пока не называют, и, видимо, не очень боятся (хотя людям с дыхательными проблемами советуют ограничить пребывание на улице).

Расстояние от этих пожаров где-то 300-400 км. Оказывается, необязательно иметь вулкан, чтобы такое устроить..

Non-commutative logical values/numbers
I'll be placing the references to systems equipped with non-commutative conjunctions in comments to this post; mostly, this will be about generalized equalities valued in quantales.

The context here is that there is a duality between metric and logical viewpoints:

http://anhinga-anhinga.livejournal.com/70309.html

This duality comes from the fact that distance can be thought about as a degree of inequality. Whether all we have here is two notions equivalent up to a dual viewpoint, or whether there are deeper dualities lurking underneath remains open.

When people consider sets equipped with equalities valued in the algebra of open sets of a topology ("Omega-sets"), the natural metric counterpart of that is the notion of partial ultrametric valued in the algebra of closed sets of the same topology. The independently made generalizations to fuzzy equalities valued in commutative quantales and to partial metrics valued in commutative quantales also coincide up to dual viewpoint/dual notation.

There is plenty of interesting work related to fuzzy equalities valued in non-commutative quantales, the references I'll be collecting here might be helpful in doing something interesting with that on the metric side.

CICM 2010
Conferences on Intelligent Computer Mathematics 2010
Paris, France, July 5-10, 2010

http://cicm2010.cnam.fr/

I am trying to figure out whether I should go there, so I'll be going through the program and noting parts which attract my interest in comments to this post.

MFPS 26

В Оттаву ехать, всё таки, облом, но есть интересные доклады, особенно Эскардо..

"I'll begin by developing and applying the topological view of computation to perform seemingly impossible practical and theoretical tasks, based on some of my papers, including "Infinite sets that admit fast exhaustive search" and "Exhaustible sets in higher-type computation". For example, (1) sets that admit exhaustive search in finite time are topologically compact, [...]"

Надо будет понять, как это работает:

Милорад Павич. "Дамаскин"
http://lib.ru/INPROZ/PAWICH/damaskin.txt

Замечательный текст (читал в сборнике "Стеклянная улитка"). Среди прочего, это один из наиболее просто структурированных гипертекстов Павича, там есть две пары глав, которые можно читать в разном порядке, давая 4 канонических варианта прочтения (получается довольно по-разному).

Это проливает некоторый дополнительный свет на то, почему книжки так сильно отличаются при мнокократном перечитывании. Конечно, читатель меняется, но у меня ещё есть привычка часто начинать читать с произвольного места -- особенно, при повторных прочтениях, или если, почему либо, начало "не идёт"..

У этого, видимо, есть некоторое приложение -- надо вносить больше разнообразия в ежедневные "движения крысы по лабиринту" (в том числе и по компьютерным лабиринтам). Даже перестановка порядка действий уже меняет дело..

*******************************************

Ещё, из приложений, по мотивам этой дискуссии:

http://turchin.livejournal.com/521098.html

поскольку существенно, как проходит субъективное время, просто некоторое замедление в хорошие моменты (например, когда визуально красиво) уже должно приводить к повышению качества жизни.

follow-up
Наиболее естественно в этой схеме, чтобы платоновские объекты, вроде множества диофантовых уравнений и связанной с этим математики, сами о себе рассказывали (их естественно считать активными).

Связь с физикой так сразу не бросается в глаза :-)
