Markov chain

Markov chain
A simple two-state Markov chain A Markov chain (discrete-time Markov chain or DTMC[1]), named after Andrey Markov, is a mathematical system that undergoes transitions from one state to another on a state space. It is a random process usually characterized as memoryless: the next state depends only on the current state and not on the sequence of events that preceded it. This specific kind of "memorylessness" is called the Markov property. Markov chains have many applications as statistical models of real-world processes. Introduction[edit] A Markov chain is a stochastic process with the Markov property. In literature, different Markov processes are designated as "Markov chains". The changes of state of the system are called transitions. A discrete-time random process involves a system which is in a certain state at each step, with the state changing randomly between steps. Many other examples of Markov chains exist. Formal definition[edit] . . of states as input, where is defined, while and Related:  Art & Technology

Blog » Blog Archive » Pimp up your camera with Arduino timelapse video tutorial – auch auf Deutsch Pimp up your camera with Arduino timelapse video tutorial – auch auf Deutsch Zoe Romano — May 25th, 2013 Last month we launched the first of a series of tutorials hosted on our Youtube Channel and created by Max of MaxTechTV in german language. Today we are publishing the second video called “Pimp-up your camera with an Arduino timelapse“. The video explains how to connect an Arduino UNO with you camera and shoot pictures, for example, every 1, 5, 10 seconds to create wonderful videos of slow processes that would normally appear subtle to the human eye. Enjoy the tutorial below and share with us the results of your experimentations! Letzten Monat haben wir das erste einer Reihe von Video-Tutorials auf unserem YouTube Kanal veröffentlicht. Heute veröffentlichen wir das zweite Video mit dem Titel “Erstelle tolle Zeitrafferaufnahmen mit deiner Kamera & Arduino”.

SPIEGEL ONLINE - Nachrichten Google search: 15 hidden features 3. Conversions Currency conversions and unit conversions can be found by using the syntax: <amount><unit1> in <unit2>. So for example, you could type '1 GBP in USD', '20 C in F' or '15 inches in cm' and get an instant answer. 4. Search for 'time in <place>' and you will get the local time for that place, as well as the time zone it is in. 5. A quick way to translate foreign words is to type 'translate <word> to <language>'. 6. If you know you are looking for a PDF or a Word file, you can search for specific file types by typing '<search term> filetype:pdf' or '<search term> filetype:doc' 7. If you type in a flight number, the top result is the details of the flight and its status. 8. Search for film showings in your area by typing 'films' or 'movies' followed by your postcode. 9. 10. When you're enter a search term that has a second meaning, or a close association with something else, it can be difficult to find the results you want. 11. 12. 13. 14. 15.

Predator takes visual object tracking to new heights – Computer Chips & Hardware Technology Cameras have slowly made their way into the portable gadgets we all carry around with us and not having a camera in a new device is viewed as a missing feature. It’s got to the point now where the latest smartphones even have two cameras so as to make for better video chat. But while the prevalence and quality of the cameras has gone up, the software still lags behind in terms of being able to identify and track objects in any real-time or captured footage. That is about to change due to the work of Czech student Zdeneki Kalai. This algorithm not only tracks, it learns the more it gets used. Kalai believes what he has created, a combination of tracking, learning, and detection is completely unique and allows for a whole new set of functionality to be applied when looking at video feeds. In the video he gives examples of a new interface that can detect your fingers and use them to draw, learning to get better at trakcing those fingers as it is used more. Read more at GottaBeMobile

Neurology of Gaming, Infographic « All Kinds of Minds As with most things, “gaming” (or being engaged in video games) has both positives and negatives when it comes to developing minds. Too much gaming, and the positive effects are overshadowed by the negative. Yet, the right balance can add another avenue for pursuing educational goals and achievement. As a result, more and more programs are using gaming to reach and teach students in ways they never could before. Therapy programs, schools, and even research scientists have all benefitted from the strategic use of games to increase successes. Below is an infographic from Online Universities looking at the brain on games. Image: Online University Like this: Like Loading...

Games and Game Design with BrainPOP The Global Education Conference is pleased to announce a new partnership with BrainPOP®, a leading creator of animated, curricular content, to develop a new gaming strand for the 2012 Global Education Conference. In addition to general session strands for teachers and students on curriculum, policy, and leadership, we are now seeking proposals for the new strand’s game-based learning sessions. The third annual Global Education Conference is an online international education extravaganza, slated to take place November 12-17, 2012. BrainPOP will be lending its expertise and support to the conference by curating the new gaming strand. Game-based learning and game design are currently hot education topics, and the Global Education Conference co-chairs are thrilled to be working with BrainPOP to highlight game play within a global education context. Please keep in mind that gaming proposals must also directly relate to the event’s mission: More about gaming....
