摘要:
An improved system and method for matching objects belonging to hierarchies is provided and an optimal matching between two feature spaces organized as taxonomies may be learned. The matching may be performed through a multi-level exploration of the hierarchical feature spaces by using multi-armed bandits where the arms of the bandit may be dependent due to the structure induced by the taxonomies. Upon the arrival of an object assigned to the first taxonomy, multi-armed bandits may be run at multiple levels of the taxonomies to select an object assigned to the second taxonomy. Then shrinkage estimation may be performed in a Bayesian framework to exploit dependencies among the arms by estimating payoff probabilities from a beta-binomial model to update payoff probabilities for matching objects from the taxonomies.

Described are a system and method for determined an event occurrence rate. A sample set of content items may be obtained. Each of the content items may be associated with at least one region in a hierarchical data structure. A first impression volume may be determined for the at least one region as a function of a number of impressions registered for the content items associated with the at least one region. A scale factor may be applied to the first impression volume to generate a second impression volume. The scale factor may be selected so that the second impression volume is within a predefined range of a third impression volume. A click-through-rate (CTR) may be estimated as a function of the second impression volume and a number of clicks on the content item.

An improved system and method for matching objects using a cluster-dependent multi-armed bandit is provided. The matching may be performed by using a multi-armed bandit where the arms of the bandit may be dependent. In an embodiment, a set of objects segmented into a plurality of clusters of dependent objects may be received, and then a two step policy may be employed by a multi-armed bandit by first running over clusters of arms to select a cluster, and then secondly picking a particular arm inside the selected cluster. The multi-armed bandit may exploit dependencies among the arms to efficiently support exploration of a large number of arms. Various embodiments may include policies for discounted rewards and policies for undiscounted reward. These policies may consider each cluster in isolation during processing, and consequently may dramatically reduce the size of a large state space for finding a solution.

A field programmable device is disclosed, including a plurality of logic blocks; a plurality of connections connecting the logic blocks; configuration circuitry for outputting configuration data for programming the field programmable device, the configuration circuitry providing at least one pair of outputs; and error detection circuitry for comparing the outputs to determine if there has been a configuration error.
摘要:
A method and apparatus for customizing content presented to individual users or user segments is provided. There may be three components, a web portal and toolbar component, a modeling component, and a scoring component. The web portal and toolbar component presents content items and collects data. The web portal and toolbar component generates user event data based on the user actions. The user event data is forwarded to the modeling component. The modeling component generates content scoring functions based on user event data and attributes of content items. Content scoring functions may be unique to individual user segments. The content scoring functions based on content features generate probability a content item will be viewed. The scoring component decides which content items are placed in a portal. The scoring component uses the scoring functions generated by the modeling component to rank content items in real time.

A method and system for assisting a user in generating a report regarding a procedure such as a medical procedure. A first display region provides a hierarchical menu of available keywords from a knowledge base. A second display region provides a hierarchical menu of particular keywords that have been selected by the user. A third display region provides a report from a sentence that was generated by populating a sentence model based on the selected keywords. The sentence can be edited by selecting a keyword from the sentence, then selecting a replacement keyword from the first display region. A grammar engine corrects the grammar of the sentence based on user settings for the keywords.
摘要:
A method and system for capturing patient related data in an endoscopic system comprising an imaging node adapted to capture and display endoscopic images during the course of an endoscopic examination. The patient data capture system and method includes a display device that provides an interface to enable a user to enter data relating to a patient examined during the examination, including patient vital sign information at various phases of care relating to the endoscopic examination and, further including individual graphic controls for enabling entry of values relating to the patient's vitals information. The entered patients vitals information is associated with a timestamp. The patient vitals information and associated timestamps are stored in a database record associated with the patient. Further data capable of being entered into the system includes medications administered, Aldrete scores and intraprocedural assessments.
