  • Patent number: 9110817
    Abstract: The present invention relates to a method for creating a Markov process that generates sequences. Each sequence has a finite length L, comprises items from a set of a specific number n of items, and satisfies one or more control constraints specifying one or more requirements on the sequence. The method comprises the steps of receiving data defining an initial Markov process of a specific order d and having an initial probability distribution and of receiving data defining one or more control constraints. The method further comprises the step of generating data defining intermediary matrices, each matrix being of dimension nd by n, by zeroing out transitions in the initial Markov process data that are forbidden by the one or more control constraints.

  • Patent number: 8856120
    Abstract: An apparatus and method for machine-updating of prototypes—for example, during design of digital objects, or content-management—has input means (15) for inputting descriptive classifiers (tags) that a user assigns to prototypes and a tag model generator (20) that uses machine learning techniques to produce a model of the association between the assigned tags and the values of quantifiable, non-subjective attributes of the tagged prototypes. In order to obtain a desired updating of a current prototype, the user issues a command which defines the desired variation of the current prototype by referring to one or more conditions that should be met by specified tags of the updated prototype. The prototype-updating apparatus/method has a prototype updater (30) that identifies a suitable updated prototype whose tags meet the condition(s) specified in the user's command and which, globally, is fairly similar to the pre-update prototype.

  • Patent number: 8838260
    Abstract: An animal-machine audio interaction system includes a sound monitor for monitoring the sounds made by one or more animals, a sound segmenter for identifying coherent sound segments within the sounds made by the animal(s), a sound analyzer for analyzing and assigning a category to each sound segment, an output sound selector for selecting an output sound appropriate to the category assigned by the sound analyzer, and a sound output unit for outputting the selected output sound to the animal(s). A different control protocol may be used to define the categories assigned to the animal sounds and to determine the respective audio responses that are appropriate to the different sound categories. During operation of the system, a closed-loop audio interaction is set up between the animal(s) and the system. This interaction may be used for various purposes, such as investigating animal behavior, entertaining the animal(s) and controlling animal behavior.

  • Patent number: 8566258
    Abstract: A new type of Markovian sequence generator and generation method generates a Markovian sequence having controllable properties, notably properties that satisfy at least one control criterion which is a computable requirement holding on items in the sequence. The Markovian sequence is generated chunkwise, each chunk containing a plurality of items in the sequence. During generation of each chunk a search is performed in the space of Markovian sequences to find a chunk-sized series of items which enables the control criterion to be satisfied. The search can be performed using a generate and test approach in which chunk-sized Markovian sequences are generated then tested for compliance with the requirement(s) of the control criteria.

  • Patent number: 8392414
    Abstract: Meta-data (tags) for an audiovisual file can be generated by producing an initial estimate of the tags and then revising the estimate (notably to expand it and/or render it more precise) based on the assumption that the relationships which hold between the different tags for a set of manually-tagged training examples will also hold for the tags of the input file now being tagged. A fully-automatic method and system is a hybrid between signal-based and machine-learning approaches, because the initial tag estimate is based on the physical properties of the signal representing the audiovisual file. The initial tag estimate may be produced by inferring that the input content will have the same tags as those files of the same kind, in the training database, which have a global similarity to the input audiovisual file in terms of signal properties.

  • Patent number: 7886229
    Abstract: A content-management interface is implemented using superposition of graphical “widget” elements onto an on-screen display of the real-time image of a user. The widgets are motion-sensitive control elements which are responsive to user movement that produces motion of the user's displayed image at an on-screen location associated with that widget. The user can operate the widget virtually, for example by moving his hand over a widget, or pushing a widget along. Meta-data descriptive of the content to be managed is mapped onto widgets, enabling the user to interact with the meta-data, notably by changing it or by selecting content with reference to it.

  • Publication number: 20100174695
    Abstract: A set of temporal phases are defined, occurring successively during the playback of music (or other content) to a user. Each temporal phase is associated with a set of selection criteria. If the user operates a selection device (which can be a computer mouse button) while a piece of music or other content is being played back, the selection phase applicable at the time of user-action is determined and further content is selected based on the selection criteria associated with the applicable phase. This enables the user, with minimal action, to influence the content being rendered. The selection criteria can be related to the meta-data of the content being played back at the time of user action. The meaning attributed to the applicable temporal phase can be varied depending on the pressure of the mouse button click.

  • Patent number: 7709723
    Abstract: Audio samples corresponding to audio extracts or whole audio titles are automatically mapped to triggers 12 in a playable sound-producing device 1, the mapping being dependent on the meta-data associated with the audio samples. Thus, a user can play the sound-producing device and generate sounds derived from his favorite audio titles. It is possible to define different mappings between the audio samples and the playable domain of the sound-producing device: an audio sample selector 50 can select between different possible samples for playback by comparing the audio properties of the samples and the play-mode and/or characteristics of the user's performance. An audio sampler/sample-processor 70 can automatically extract segments of an audio source file and map them to triggers in the sound-producing device 1.
