Le cerveau, objet technologique (1/8) : Hacker le cerveau Par Rémi Sussan le 07/01/09 | 30 commentaires | 14,769 lectures | Impression Dans la perspective d’une convergence des nouvelles technologies dans ce qu’on appelle les NBIC (neurosciences, biotechnologies, informatique et cognition, voir l’explication qu’en donne Jean-Michel Cornu), la cognition est celle dont la présence reste la plus mystérieuse. Il est facile de saisir l’aspect technologique des nanotechnologies, de la biotechnologie ou, bien sûr, de l’informatique. Mais la cognition n’est-elle pas quelque chose de plus abstrait, de plus fondamental ?
Dynamic Networks This topic discusses how the format of input data structures affects the simulation of networks. It starts with static networks, and then continues with dynamic networks. The following section describes how the format of the data structures affects network training. There are two basic types of input vectors: those that occur concurrently (at the same time, or in no particular time sequence), and those that occur sequentially in time. The 101 Most Useful Websites on the Internet Here are some of the most useful websites on the internet that you may not know about. These web sites, well most of them, solve at least one problem really well and they all have simple web addresses (URLs) that you can memorize thus saving you a trip to Google. And if you find this list useful, also check out the expanded version – The Most Useful Websites – which now offers a collection of 150+ undiscovered and incredibly useful websites to enhance your productivity. ctrlq.org/screenshots – for capturing screenshots of web pages on mobile and desktops. dictation.io – online voice recognition in the browser itself. Changelog and Updates The following websites were part of the original list but they are either no longer available or have been replaced with better alternatives.
NARX All the specific dynamic networks discussed so far have either been focused networks, with the dynamics only at the input layer, or feedforward networks. The nonlinear autoregressive network with exogenous inputs (NARX) is a recurrent dynamic network, with feedback connections enclosing several layers of the network. The NARX model is based on the linear ARX model, which is commonly used in time-series modeling. The defining equation for the NARX model is where the next value of the dependent output signal y(t) is regressed on previous values of the output signal and previous values of an independent (exogenous) input signal. You can implement the NARX model by using a feedforward neural network to approximate the function f. 10 Free Web Tools For Teachers Being Used Right Now The internet is agog with useful resources for teaching one way or another. Tutors, teachers and of course students are already benefiting from the use of such tools. And, a great thing about them is that a lot of these resources are actually available for use absolutely free of any charge.
Invisible Web: What it is, Why it exists, How to find it, and Its inherent ambiguity What is the "Invisible Web", a.k.a. the "Deep Web"? The "visible web" is what you can find using general web search engines. It's also what you see in almost all subject directories. The "invisible web" is what you cannot find using these types of tools. The first version of this web page was written in 2000, when this topic was new and baffling to many web searchers.

Want to research using the Internet? Good luck. There’s a lot of junk out there — outdated pages, broken links, and inaccurate information. Using Google or Wikipedia may lead you to some results, but you can’t always be sure of accuracy. Perform specified logical operation on input - Simulink Perform specified logical operation on input Library Logic and Bit Operations Description The Logical Operator block performs the specified logical operation on its inputs. An input value is TRUE (1) if it is nonzero and FALSE (0) if it is zero.
Connect Blocks Automatically Connect Blocks You can have the Simulink® software connect blocks automatically. This eliminates the need to draw the connecting lines yourself. When connecting blocks, Simulink routes the lines around intervening blocks to avoid cluttering the diagram. Autoconnect Two Blocks When connecting two blocks with multiple ports, Simulink draws as many connections as possible between the two blocks. List of LaTeX mathematical symbols - OeisWiki From OeisWiki All the predefined mathematical symbols from the TeX package are listed below. More symbols are available from extra packages. Greek letters Unary operators Relation operators Creator Processing ... Personal $ Svg $20 ✓ Greek letters used in mathematics, science, and engineering The Bayer designation naming scheme for stars typically uses the first Greek letter, α, for the brightest star in each constellation, and runs through the alphabet before switching to Latin letters. The majority of English-speaking mathematicians use neither the modern nor the historical Greek pronunciations of the names of the letters, but the traditional English pronunciation, e.g. /ˈθeɪtə/ for θ (US pronunciation), cf. ancient [tʰɛ̂ːta] and modern [ˈθita].
