A data compression system includes: (a) a data compression module that receives a sequence of input vectors and that provides a sequence of compressed vectors; (b) a data decompression module that receives the compressed vectors to provide a sequence of output vectors; and (c) a parameter update module that receives the sequence of input vectors and the sequence of output vectors, and which learns the data compression module and data decompression module based on evaluating a loss function of the input vectors, the output vectors, and the parameters controlling the compression module and the decompression module. Each input vector and its corresponding output vector may represent digitized time-domain signals (e.g., speech, audio or video signals) over a predetermined time period. The loss function may be evaluated for each of a sequence of predetermined time periods.

A method provides program structures for constructing a program that is learned over training data. In one example, two specific program structures are provided in which the first program structure transforms each vector in an input tuple of vectors to provide an output tuple of vectors, and the second program structure operates on an input tuple of vectors to provide an output tuple of vectors by applying one or more transformations that each involves two or more vectors in the input tuple. The transformations of the first and second program structures may be linear transformations. The program may alternatively execute the first program structure and the second program structure in any suitable order a number of times, beginning with operating one of the program structures on an initial tuple of vectors. The vectors may each consist of an ordered set of real numbers.

A method and an apparatus to provide a personalized page to a user have been disclosed. In one embodiment, a user is identified as a member of a first group and a member of a second group. The first group's level of interest (LOI) in a first item is identified, as well as the second group's LOI in a second item. The user's LOI in at least one of the first and the second items is identified.

An apparatus and a method are provided for learning a program with a large number of parameters. In one embodiment, a method not only distorts the input values, but also distorts some of the parameters in the program model. Such an approach not only forces the learned program to acquire parameter values to predict missing or desired data, but also to correct errors in the input data and the program parameters themselves, thereby rendering the learned program more resilient to overfitting and falling into local optima.

Upon receipt of a document request, a client assistant examines its cache for the document. If not successful, a server searches for the requested document in its cache. If the server copy is still not fresh or not found, the server seeks the document from its host. If the host cannot provide the copy, the server seeks it from a document repository. Certain documents are identified from the document repository as being fresh or stable. Information about each of these identified documents is transmitted to the server which inserts entries into an index if the index does not already contain an entry for the document. If and when this particular document is requested, the document will not be present in the server, however the server will contain an entry directing the server to obtain the document from the document repository rather than the document's web host.

The present invention is directed to a method for updating a cache. A server identifies whether certain preconditions have been met for a document in a cache from freshness parameters associated with a document identifier for the document. Then when the preconditions have been met, a first document content is retrieved from a remote host. A first content fingerprint for the first document content is calculated. The first document content is stored in the cache. Then a content difference is calculated between the first document content and a second document content, both associated with the document identifier. The content difference is stored. Then the document identifier is associated with the content difference.

Methods and apparatus consistent with the invention provide improved organization of documents responsive to a search query. In one embodiment, a search query is received and a list of responsive documents is identified. The responsive documents are organized based in whole or in part on usage statistics.
摘要:
A micro-payment system has buyers, sellers, and a broker. The buyers establish accounts with the broker and provide payment information allowing the broker to invoice the buyers. The sellers establish accounts with the brokers and specify terms for accessing items, including electronic content, available from the sellers. The sellers also provide payment information that allows the broker to credit the sellers for sales of the items. The broker aggregates the buyers' micro-payment purchases and invoices the buyers. The broker also aggregates the sellers' micro-payment sales and credits the sellers.
