  • Gibbs
  • Maximum entropy (ME) models, variously known as log-linear, Gibbs, exponential, and multinomial logit models, provide a general purpose machine learning technique for classification and prediction which has been successfully applied to fields as diverse as computer vision and econometrics. (repec.org)
  • 1971
  • However, in 1971, Romanian economist Nicholas Georgescu-Roegen published The Entropy Law and Economic Process, formulating what he called ' Bioeconomics ', exposing certain errors in conventional economic theory. (greenpeace.org)
  • Neumann
  • Von Neumann told him he should call it the "entropy" because nobody really knows what entropy is (indeed it does appear to be a loaded term ) and thus Shannon would have an advantage when debating his burgeoning field with pundits. (cisco.com)
  • system
  • Once you have given the box a good shake, you have pretty much maximized the entropy of the system. (tripod.com)
  • Note that the collapse of the proto-solar system did not cause an increase in the entropy of some larger system as we would find in the classic refrigerator example. (tripod.com)
  • The entropy inside the icebox is lower than that of the surrounding kitchen, but in running the motors of the fridge we have heated up the kitchen and the entropy of a larger system was increased in order to lower the entropy around our cold cuts and beer. (tripod.com)
  • Entropy CAN in fact be reduced in a closed system, and this happens spontaneously according to the fluctuation theorem. (physicsforums.com)
  • In either case, entropy of a closed system does not decrease. (physicsforums.com)
  • For a many-body system in local equilibrium a stronger version of the second law applies which says that the entropy production at each spacetime point should be non-negative. (colorado.edu)
  • Topological entropy is a nonnegative number which measures the complexity of the system. (scholarpedia.org)
  • physics
  • Their work, entitled "Influence of temperature and diffusive entropy on the capture radius of fly-casting binding", was published in SCIENCE CHINA Physics, Mechanics & Astronomy, 2011, 54(12). (redorbit.com)
  • In the meantime, Callisto reflects on the concept of entropy, on the possibility that the universe will ultimately suffer heat death and cease to act at all (the first sign of which is the constant thermometer reading outside his window), and on the possible implications of the laws of thermodynamics for social existence (this with some help from those investigators who had appropriated the term "entropy" from physics to information theory). (enotes.com)
  • equally
  • For example, the entropy of a coin flip with 2 equally likely outcomes is less than that of the roll of die with 6 equally likely outcomes. (cisco.com)
  • If these values are equally probable, the entropy (in bits) is equal to this number. (wikipedia.org)
  • time
  • Another thing you can demonstrate with the shoebox entropy machine, is something that some people say can not happen, but in fact happens all of the time. (tripod.com)
  • complexity
  • The second law of thermodynamics allows higher order (lower entropy) to appear locally, but it still disallows organized complexity. (talkorigins.org)
  • maximum
  • In the state of maximum entropy we would expect to find about 50 cents showing heads and fifty cents showing tails. (tripod.com)
  • Maximum entropy is a powerful method for constructing statistical models of classification tasks, such as part of speech tagging in Natural Language Processing. (sourceforge.net)
  • main
  • You have probably heard that the main statement of entropy is that systems always tend to become more disordered. (tripod.com)
  • make
  • The only difference is that I averaged the entropies of larger files to make sure that the dataset is small enough for the line chart component to handle. (the-interweb.com)
  • It is important to make the distinction that entropy is not information. (cisco.com)
  • I would like to make a stand regarding the topic of entropy reversal. (physicsforums.com)
  • important
  • The purpose of this volume is to present some of these recent and important results in a manner that not only appeals to the entropy specialist but also makes them accessible to the nonspecialist looking for an overview of the field. (springer.com)
  • state
  • The all heads condition is just one possible state for the entropy machine of 2^100 possible states. (tripod.com)
  • Once you have achieved this state, entropy can not increase any further so it must stay the same or decrease. (tripod.com)
  • Data
  • Our direct analysis of the experimental data from the staggered herringbone mixer mixer demonstrates the adaptability of the entropy and multifractal dimensions to both simulations and experiments. (nsti.org)
  • Rate
  • CONSPECTUS: The role played by entropy for the enormous rate enhancement achieved by enzymes has been debated for many decades. (diva-portal.org)
