摘要： An educational recommender system and a method are provided. The method includes receiving a request to recommend a course of action related to a plurality of current students; accessing a computer database storing student data that corresponds to the plurality of current students; clustering in a computer process the plurality of current students into at least two clusters based at least on granular assessment data associated with student data corresponding to respective current students; and outputting the results of the clustering to a user. The granular assessment data includes a result of an assessment administered to respective students of the plurality of current students, and each assessment includes a plurality of questions for assessing one of the current students. The associated result includes an independent evaluation of each respective question of the plurality of questions.

摘要： An apparatus and method are provided for generating a representation of an image which may be used in tasks such as classification, clustering, or similarity determination. An image, such as a scanned document, in which the pixel colorant values are quantized into a plurality of colorant quantization levels, is partitioned into regions, optionally at a plurality of different scales. For each region, a runlength histogram is computed, which may be a combination of sub-histograms for each of the colorant quantization levels and optionally each of plural directions. The runlength histograms, optionally normalized, can then be combined to generate a representation of the document image.

摘要： An object comparison method comprises: generating a first ordered vector sequence representation (22) of a first object; generating a second ordered vector sequence representation of a second object; representing the first object by a first ordered sequence of model parameters generated by modeling the first ordered vector sequence representation using a semi-continuous hidden Markov model employing a universal basis; representing the second object by a second ordered sequence of model parameters generated by modeling the second ordered vector sequence representation using a semi-continuous hidden Markov model employing the universal basis; and comparing (40) the first and second ordered sequences of model parameters to generate a quantitative comparison measure.

摘要： A system and method for computing confidence in an output of a text recognition system includes performing character recognition on an input text image (10) with a text recognition system to generate a candidate string of characters. A first representation (16) is generated, based on the candidate string of characters, and a second representation (20) is generated based on the input text image. A confidence (28) in the candidate string of characters is computed based on a computed similarity between the first and second representations in a common embedding space.

摘要： A system and method for computing a place profile are disclosed. The method includes providing (S104) a geographical definition of a place, retrieving (S106) a set of images based on the geographical place definition. With a classifier, image-level statistics for the retrieved images are generated (S108). The classifier has been trained to generate image-level statistics for a finite set of classes, such as different activities. The image-level statistics are aggregated (S110) to generate a place profile for the defined place which may be displayed to a user who has provided information for generating the geographical definition or used in an application such as a recommender system or to generate a personal profile for the user.

摘要： A system and a method of querying a remote service (14) without revealing a private document to the remote service are provided. The method includes receiving a signature of a user's private document, and querying an intermediate database (28) with the signature of the private document to generate an intermediate result set (58) comprising intermediate database documents, based on a computation of similarity of the signatures of the intermediate database documents to the signature of the private document. The remote service (14) is queried, based on the intermediate result set (58) and a final result set (76) is received from the remote service based on the query, which can be output to the user or further processed.
