    摘要: In a genetic optimization method, the genes of a chromosome population are computationally genetically evolved. The evolving includes evolving a number of expressed genes in each chromosome and employing a fitness criterion evaluated without reference to unexpressed genes of each chromosome. An optimized chromosome produced by the genetic evolving is selected.

    摘要: A medical apparatus (901, 100) assists clinicians, nurses or other users in choosing an intervention for the treatment of a patent suffering from an acute dynamic disease, e.g. sepsis. The medical apparatus is based on a method where a model of the disease is adapted or personalized to the patient. To ensure that the apparatus remains capable of predicting the health of the patient, the apparatus is continuously provided with new, more recent patient values and the model is continuously adapted to the new patient values. Since the medical apparatus is configured to be continuously adapted to current state of health, the apparatus is able to assist the user by generating disease management information, e.g. suggestions for medications, to an output device (902, 104).

    摘要: A method for determining the presence or absence of malignant features in medical images, wherein a plurality of base comparison or training images of various types of lesions taken of actual patient is examined by one or more image reading experts to create a first database array. Low-level features of each of the lesions in the same plurality of base comparisons or training images are determined using one or more image processing algorithms to obtain a second database array set. The first and second database array set are combined to create a training database array set which is input to a learning system that discovers/learns a classifier that maps from a subset of the low-level features to the expert's evaluation in the first database array set. The classifier is used to determine the presence of a particular mid-level feature in an image of lesion in a patient based solely on the image.

    摘要: A method of automatically identifying the microarray chip corners and probes, even if there are no probes at the corners, in a high density and high resolution microarray scanned image having an image space, wherein the method minimizes the error distortions in the image arising in the scanning process by applying to the image a multipass corner finding algorithm comprising: (a) applying a Radon transform to an input microarray image to project the image into an angle and distance space where it is possible to find the orientation of the straight lines; (b) applying a fast Fourier transform to the projected image of (a) to find the optimal tilting angle of the projected image; (c) determining the optimal first and last local maxima for the optimal tilting angle; (d) back projecting the determined first and last local maxima to the image space to find the first approximation of the first and last column lines of the image; (e) rotating the image and repeating steps (a) through (d) to find the first approximation of the top and bottom row lines of the image; (f) determining the first approximation of the four corners of the image from the intersection of the column and row lines; (g) applying a heuristic for determining if the first approximation of step (f) is sufficient; and (h) optionally trimming the scanned image around the first approximation of the four corners and repeating steps (a) through (f).

    摘要: A method (800) and apparatus (100) are disclosed for predicting a level of interest in an item, such as the size of an audience for a television program, based on the selection history (120) of multiple users and the extent to which the item is recommended (220) to the multiple users. The size of an audience for a given program can be predicted based on, for example, the percentage of users to which the given program is “highly recommended.” A method (900) for calibrating the accuracy of the predictions using measurement data indicating the actual size of the audience is also disclosed. A comparison of the predicted and actual audiences allows a correction factor to be generated to improve subsequent predictions.

    摘要: A security system incorporating a reasoning system and security rules and processes. Transponders may be triggered and sensed from a distance to identify both items and individuals. These sensed identifiers are processed by the reasoning system to determine whether each identified item is authorized to be removed from or brought into a secured location by the identified individual. The system modifies and optimizes its rules and processes based on assessments of security events. The security system enforces these security rules and receives feedback from authorized security personnel. A learning system is configured to modify existing rules or create new rules in conformance with the feedback from the authorized security personnel.

    摘要: A reconfiguration manager implemented on a computer or other data processing device controls the reconfiguration of software or other components of an electronic device such as a computer, personal digital assistant (PDA), set-top box, television, etc. The reconfiguration manager receives a reconfiguration request, e.g., a software upgrade request from the electronic device, and determines one or more device components that are required to implement the reconfiguration request. The reconfiguration manager also determines, e.g., from information in the request, identifiers of one or more additional components currently implemented in the electronic device. The reconfiguration manager then compares the needed and currently implemented components with previously-stored lists of known acceptable and unacceptable configurations for the electronic device. If the needed and currently implemented components correspond to a configuration on the list of acceptable configurations, the request is approved and the needed components are downloaded to the electronic device. If the needed and currently implemented components correspond to a configuration on the list of unacceptable configurations, the request is denied. Otherwise, the reconfiguration manager may indicate that the requested reconfiguration is unknown, or may take another action such as responding to the electronic device with a list of other components that would be required to implement the request.

    摘要: The step size parameters of a component placement machine are represented as genes in a component placement chromosome, and evolutionary algorithm techniques are applied to evolve offspring that have step size parameters that provide an improved component placement throughput estimate. The offspring that have these preferential step size parameters are used to generate additional offspring that provide further improvement in the component placement throughput estimate. After a number of generations, the step size parameters of the offspring that provides the best component placement throughput are used to program the component placement machine to achieve this improved throughput.
