Erik P. Causal interactions within complex systems such as the brain can be analyzed at multiple spatiotemporal levels. It is widely assumed that the micro level is causally complete, thus excluding causation at the macro level. In this work, we go beyond effective information and consider additional requirements of a proper measure of causal power from the intrinsic perspective of a system: composition the cause—effect power of the parts , state-dependency the cause—effect power of the system in a specific state ; integration the causal irreducibility of the whole to its parts , and exclusion the causal borders of the system. This happens if coarse-graining micro elements produces macro mechanisms with high irreducible causal selectivity.

Causal density and integrated information as measures of conscious level.

Curator: Anil Seth. Eugene M. Marc-Oliver Gewaltig. A model of consciousness is a theoretical description that relates brain properties of consciousness e. Because of the diverse nature of these properties Seth et al.

And yes, it will contain that quantitative calculation. Ironically, Maguire et al. Unfortunately, none of those articles will tell you the meat i. Faced with this point, many scientifically-minded people start yelling and throwing things. Fortunately, I think IIT survives the above observations. But I also regard IIT as a failed attempt on the problem.

Causal density and integrated information as measures of conscious level

The grand quest for a scientific understanding of consciousness has given rise to many new theoretical and empirical paradigms for investigating the phenomenology of consciousness as well as clinical disorders associated to it. A major challenge in this field is to formalize computational measures that can reliably quantify global brain states from data. In particular, information-theoretic complexity measures such as integrated information have been proposed as measures of conscious awareness.

We use simulations to demonstrate the in-practice applicability of our measures, and to explore their properties. Our results provide new opportunities for examining information integration in real and model systems and carry implications for relations between integrated information, consciousness, and other neurocognitive processes. However, our findings pose challenges for theories that ascribe physical meaning to the measured quantities.

 Если бы я не нашел черный ход, - сказал Хейл, - это сделал бы кто-то. Я спас вас, сделав это заранее. Можешь представить себе последствия, если бы это обнаружилось, когда Попрыгунчик был бы уже внедрен. - Так или иначе, - парировала Сьюзан, - теперь мы имеем параноиков из Фонда электронных границ, уверенных, что черный ход есть во всех наших алгоритмах. - А это не так? - язвительно заметил Хейл. Сьюзан холодно на него посмотрела.

Никто не знает, как поведет себя общество, узнав, что группы фундаменталистов дважды за прошлый год угрожали ядерным объектам, расположенным на территории США. Ядерное нападение было, однако, не единственной угрозой. Только в прошлом месяце благодаря ТРАНСТЕКСТУ удалось предотвратить одну из самых изощренных террористических акций, с которыми приходилось сталкиваться агентству. Некая антиправительственная организация разработала план под кодовым названием Шервудский лес. Его целью была Нью-Йоркская фондовая биржа, а замыслом - перераспределение богатства. За шесть дней члены группы установили в зданиях вокруг биржи двадцать семь взрывобезопасных легкоплавких контейнеров.

 Не волнуйтесь, мадам, - заверил второй агент.  - С ним все будет в порядке. Дэвид Беккер смотрел на экран прямо перед. У него кружилась голова, и он едва отдавал себе отчет в происходящем. На экране он видел комнату, в которой царил хаос. В этой комнате находилась Сьюзан. Она стояла отдельно от остальных и смотрела на него, смеясь и плача.

Но, ожив, монитор вновь показал то же. Чатрукьяну вдруг стало холодно.

  • measures of conscious level​​ Here, we describe recent progress in the development of measures of dynamical complexity, in particular causal density and integrated information. These and similar measures capture in different ways the extent to which a system's dynamics are simultaneously differentiated and integrated. Raoul T. - 03.06.2021 at 20:11
