摘要： A method for providing product recommendations to customers in an e-commerce environment includes the step of generating content and compatibility representations of products corresponding to a plurality of customers. A similarity function is calculated between pairs of content attributes corresponding to the products. A similarity function is calculated between pairs of compatibility attributes corresponding to the products. The plurality of customers are clustered into a plurality of peer groups. For a given customer, a closest peer group of the plurality of peer groups is determined. At least one potential recommendation is then generated for the given customer based on the closest peer group.

摘要： A hybrid scheme for controlling transmission errors in digital data communication systems. Normally, data blocks with a small number of parity digits for error detection are transmitted. When the presence of errors is detected, the retransmissions are not the original data blocks but some properly selected blocks for correcting errors in those erroneously received data blocks which are stored in a buffer at the receiver. The retransmitted blocks are formed based on the original data blocks and error-correcting codes with an invertible property. When such blocks are received, they are used to recover the original data blocks either by an inversion operation or by a decoding process.

摘要： Systems and methods for embedding metadata such as personal patient information within actual medical data signals obtained from a patient are provided wherein two watermarks, a robust watermark and a fragile watermark are embedded in a given medical data signal. The robust watermark includes a binary coded representation of the metadata that is incorporated into the frequency domain of the medical data signal using discrete Fourier transformations and additive embedding. Error correcting code can also be added to the binary representation of the metadata using Hamming coding. A given robust watermark can be incorporated multiple times in the medical data signal. The fragile watermark is added on top of the modified medical signal containing the robust watermark in the spatial domain of the modified medical signal. The fragile watermark utilizes hash function to generate random sequences that are incorporated through the medical data signal.

摘要： One embodiment of the present method and apparatus adaptive load shedding includes receiving at least one data stream (comprising a plurality of tuples, or data items) into a first sliding window of memory. A subset of tuples from the received data stream is then selected for processing in accordance with at least one data stream operation, such as a data stream join operation. Tuples that are not selected for processing are ignored. The number of tuples selected and the specific tuples selected depend at least in part on a variety of dynamic parameters, including the rate at which the data stream (and any other processed data streams) is received, time delays associated with the received data stream, a direction of a join operation performed on the data stream and the values of the individual tuples with respect to an expected output.

摘要： Introduced herein is a “resource adaptive” algorithm for spectrum and periodicity estimation on a continuous stream of data. The formulation is based on the derivation of a closed-form incremental computation of the spectrum, augmented by a load-shedding scheme that can adapt to available CPU resources to provide a resource efficient solution for real time spectrum estimation.

摘要： A system and method for supporting offline Web browsing. A user interests profile comprising content and attribute preferences of Web pages the user may be interested in is provided. Based on that user's profile, there is generated an interestingness values value for each of candidate Web pages. From a hoard request initiated by a user, received one or more Web pages are selected and downloaded based on their respective interestingness values. These Web pages are stored for later viewing by the user when offline. The candidate Web pages include base Web pages which are supplied by the user in the hoard request, and linked Web pages which are reachable from the base pages. Thus, an interestingness value may be computed as the interestingness of a hyperlink associated with a Web page reachable from a base Web page, the interestingness value of a hyperlink being based upon the similarity of a linked Web page to the base Web page and/or to that user's interests profile.
