The Chernoff information was originally introduced for bounding the probability of error of the Bayesian decision rule in binary hypothesis testing. Nowadays, it is often used as a notion of symmetric distance in statistical signal processing or as a way to define a middle distribution in information fusion. Computing the Chernoff information requires to solve an optimization problem that is numerically approximated in practice. We consider the Chernoff distance for distributions belonging to the same exponential family including the Gaussian and multinomial families. By considering the geometry of the underlying statistical manifold, we define exactly the solution of the optimization problem as the unique intersection of a geodesic with a dual hyperplane. Furthermore, we prove analytically that the Chernoff distance amounts to calculate an equivalent but simpler Bregman divergence defined on the distribution parameters. It follows a closed-form formula for the singly-parametric distributions, or an efficient geodesic bisection search for multiparametric distributions. Finally, based on this information-geometric characterization, we propose three novel information-theoretic symmetric distances and middle distributions, from which two of them admit always closed-form expressions. © 1994-2012 IEEE.

A slide cover has a engaged portion formed thereon. A rotatable member includes a stopper portion which is abutted against the engaged portion so as to restrict a relative movement of the engaged portion of the slide cover when the slide cover is arranged at a closed position. The stopper portion is positioned away from a rotation center of the rotatable member, and the rotatable member rotates to allow the relative movement of the engaged portion when the stopper portion is pushed by the engaged portion. This makes it possible to increase an angle between an stopper surface formed on the stopper portion and a movement direction (right-left direction) of the engaged portion. As a result, the cover is stably held at the closed position.

The music industry has seen its profits decrease drastically since 2000, challenged by other forms of entertainment such as video games and the internet, as well as by illegal download and piracy. However, there is a growing activity in the so-called music synchronization business: music composed, retrieved, or otherwise produced to fit with the many constraints of videos, movies, games or commercials. Synchronized music has to satisfy complex constraints, specified temporally (specific events at specific moments, or, in the case of interactive music, specific moods matching the players situation, etc.). Major movie, game and advertisement companies devote considerable budgets to get synchronized music by famous artists. Producing such synchronized music is a costly process currently performed manually by well-known artists or specialized studios. This results in prohibitive costs for high-quality synchronized music, that only a few professional customers can afford. The commercial value of synchronized music lies in the style of the composer. Style is what makes an artists music easily recognizable: Paul McCartney has a unique composition style, Joao Gilberto has a distinctive guitar accompaniment style, and Take 6 are well known for their incomparable harmonization style. Producing operational representations of style is precisely the subject matter of the ERC project Flow-machines, which already produced scientific and technical breakthroughs: turning style into a new content type is within reach. The next step is to explore commercial strategies to exploit style. The goal of this PoC project is to apply these techniques to synchronized music, and to study three business models in the movie, game and advertisement sectors. The project will: 1) develop a style manipulation prototype for synchronized music, 2) evaluate the prototype in the key industrial sectors and 3) clear legal issues related to the exploitation of style information.

A method of reducing interference to reception of streams of television content received at a television receiver in which each of the streams of television content are transmitted on one of a plurality of frequency channels in accordance with a channel map which defines on which of the plurality of frequency channels each stream of television content is transmitted and the interference being caused by a base station transmitting data to or receiving data from one or more mobile devices via radio communication signals in a vicinity of the television receiver. The method includes identifying the channel map and adapting a transmission of the radio communication signals between the base station and the one or more of mobile devices in accordance with the identified channel map to reduce interference at the television receiver.
