integrated information theory simplified

On the other hand, if the internet became more integrated than the human brain (when the internet is understood as a system that includes the brains of its users as parts, not just inputs to it) then the internet as a whole would become conscious and our own consciousnesses would be absorbed into it as parts! For instance, my full first name is Lê Nguyên.But in western countries, people simply call me Lê.Meanwhile, in Vietnam, people rather use my full first name. Thus, there is a path to developing significant artificial consciousness, albeit a quite indirect and circumscribed one. The benefit of this theory is that it provides a physiological basis for the complex phenomenon of pain. This motivated a large amount of theoretical work on sparse graph codes and iterative decoding methods.

The second axiom claims that consciousness is structured: it contains a variety of qualities at once; a mix of colors, sounds, emotions, thoughts, and so on (one might object that there are experiences of complete darkness that contain no qualities – but such an experience would still contain structure such as the left and right side of the empty visual field). Thus: “[Koch] is not saying that information causes consciousness; he is saying that certain information just is consciousness, and because information is everywhere, consciousness is everywhere.

The images A to C (Figure 7) in fact comprise one and the same object, viewed from three different orientations. That is, if we accept Turing’s definition according to which anything to which you can assign a 0 and a 1 is a computer, then the window is a simple and trivial computer.”. Furthermore, how can systems that adapt to their previous inputs (learn from them) fit into the rather static formulation of classic information theory? IIT’s next requirement for consciousness is integration. The common frequency of these two rhythms is the “tremor” 5 Hz rhythm.

Books, photographs and hard drives are typically regarded as containing a lot of information. Figure 38.1.

Introduction Integrated Information Theory (IIT), developed by Giulio Tononi and collabora-tors, has emerged as one of the leading scientiﬁc theories of consciousness [OAT14, It would also have implications for the hard problem of consciousness: the philosophical question of why and how physical processes can give rise to subjective experience. These results were later proved to provide a lower bound using Guerra's interpolation technique [21], cf. How can information be information without minds or observers? But in a computer, at least as we make them today, every transistor is connected to only a few other transistors, so if we cut it in two much less structure would be lost. So, does consciousness go all the way down?

Such things do communicate with each other in terms of causes and effects. It’s been seen as a truly emergent phenomenon.

That means that such extra information (of that informational system) must emerge from the information contained in its parts. Consciousness is something with which we’re all intimately familiar.

The ‘fraction’ of the space of all possible events that an event ai (e.g., obtaining the letter i when reading the first digit) takes can be measured by its probability p(ai). How does integrated information theory deal with information?

As for dynamics: if there’s an event which affects a dynamic system, then that event can read as information. On the other hand, another part of the brain, the cerebellum, is important for motor functions, balance, and so on, but doesn’t directly support consciousness.
The brain is of course influenced by external conditions too, such as the sensory environment and bodily processes.

and integration (i.e., the experience of all differentiated elements at once) (Oizumi et al., 2014). deﬁnition of the theory which may serve as the starting point for future formal investigations and as an introduction suitable for researchers with a formal background. Information theory is the mathematical treatment of the concepts, parameters and rules governing the transmission of messages through communication systems. If IIT is correct, we could in principle measure the consciousness of any system by measuring its Φ. [For more about panpsychism, see Philip Goff’s article in this issue.].

But even so, it remains to be seen whether IIT’s particular first-person case can withstand closer scrutiny and criticism.

The fundamental measures of entropy and MI form the basis of more complex information measures that describe higher-order statistical relationships between three or more variables. This, then, seems to be a commitment to some kind of emergentism. Indeed in the field called pancomputationalism (just about) anything can be deemed to be information. IIT extracts these ideas from the first-person perspective, translates them into a precise mathematical measure, and tests the measure against third-person observations. The conditional entropy (or mutual information) for this systems was initially computed using non-rigorous statistical mechanics methods [17–19] using a correspondence first found by Nicolas Sourlas [20]. However, information is also said to exist without minds (or observers). Thus, just as the window is only a computer to minds/observers, so too is that window’s information only information to minds/observers. For an introduction to the subject and a more comprhensive list of references see [13] as well as the upcoming book [14]. In the context of GRN inference, the expression level of each gene is treated as a random variable, with the observed expression profile providing an empirical estimate of the probability distribution. By randomly adding new connections to a population of machines, and imposing conditions that select for the more efficient and adaptable ones, then repeating the process many times, one might succeed in selecting for integration, and by the same token, consciousness. IIT sets no minimal threshold of Φ required for consciousness. Take the brain’s neurons. Perhaps then the first-person perspective provides some crucial insight into the nature of consciousness. These postulates are then given a mathematical interpretation, yielding the full version of IIT.

Hawking’s theory implied that, over time, a black hole would eventually evaporate away, leaving nothing. This information must be based on the system’s causal powers, not on symbolic conventions. But higher Φ might be found on some other scale for inanimate objects. The answer is: all and only those with maximal Φ.

Clearly, in these senses, an open and shut window also contains information. Comparisons consistently show CLR outperforms ARACNE, MRNET and correlation-based approaches (Marbach et al., 2012; Ish-Horowicz and Reid, 2017; Chan et al., 2017), and demonstrate further performance gains for PIDC when using single-cell data (Chan et al., 2017). This would justify some common practices toward lower organisms – for example, the suffering and death of bacteria by penicillin is arguably worth the benefits it brings humans, given our vast difference in Φ.

Consciousness doesn’t equal just any kind of information; though any kind of information (if embodied in a system) may be conscious (at least to some extent). Information theory studies reveal that the information encoded by the simultaneous activity of neurons can be independent, redundant or synergistic (Schneidman et al., 2003).

Another important question that’s hard to answer without a theory is whether and to what extent animals are conscious – especially animals that are very unlike us, such as octopuses, fish, or insects. Therefore, the internal structure (dealing with the object itself) does not vary between the images. Hence, compared to the example with the numbers, the reading of each letter must provide a greater reduction in uncertainty. Nonetheless, a system can be more than the sum of its parts without any commitment to strong emergence.

Systems with a low Φ, the theory goes, have a small amount of consciousness – they only have very simple and rudimentary experiences. In this example, each time we read a digit, our uncertainty was reduced. Information manipulation theory (IMT) is a theory of deceptive discourse design, authored by interpersonal communication scholar Steven McCornack. (1994) demonstrated that that judged similarities between objects largely rely on structural aspects, leaving a secondary, non-dominant, role for metrical aspects (more specifically it was shown that such judgements followed classifications based on constancy and symmetry of the descriptive parts rather than their size). There are many questions one could raise about this argument. Indeed, this could be what happens temporarily, in deep sleep: we think consciousness entirely disappears, but it might actually just change into a fragmented form (which is no longer recognizable as ‘our’ consciousness).
