Abstract: A computer-implemented method of managing product data is provided, which includes generating a first time segment associated with a first product sale feature, the first time segment including product sales data related to sales of the product at a point of sale per a first time unit over a first time period in the past starting on a current time and of a first predetermined duration expressed in the first time unit, and one or more second time segments respectively associated with one or more second product sale features. The second time segments each include context data associated with product sale history and/or the point of sale over the first time period in the past. The first time segment is combined with the one or more second time segments to generate an information vector of product sale features. A prediction of sales for the product at the point of sale is generated based on the output of a prediction model to which the information vector of product sale features is input.

Abstract: A method and system of communication in a wide band high frequency HF communication system is disclosed. The system includes at least n communication channels, an interleaver common to the n communication channels, a means for determining the quality of communication of each of the n communication channels. At least the following information is introduced into the structure of the frame of the data at the level of an autobaud: an item of information about the modulation employed on each of the n communication channels chn, an item of information about the interlever common to the n communication channels, the corrector code FEC employed, the number of communication channels employed (n) as well as for each one its identifier idn. The modulation is chosen on channel n, a common coding and interleaving are operated on the n channels, and the information introduced in the shared autobaud is transmitted.

Abstract: A method and system are provided for reducing the peak factor in a multi-carrier communication system, the data being transmitted on m channels comprising, in the transmission of data in the form of a frame, a step in which a number d of desynchronization symbols are introduced at the start of each of the frames, the number d being chosen as a function of the transmission channel number concerned.

Abstract: The approach of the invention offers a compromise between various problems: number of languages processed, labeling of phonemes, speed. Its principle is acoustic discrimination of languages, which is performed with a neural modeling guaranteeing a low calculation time on execution (for example less than 3 seconds). Furthermore, neural networks generally perform very good discriminations since their prime vocation is to create separator hyper-planes between the various languages taken pairwise. In summary, the invention applies a principle of inter-discrimination of languages, by opposing of language pairs, then by merging the results.
