In several aspects for generation of high quality synthetic observability data for computing systems, traces and logs from a system are collected as a seed dataset. Multiple conditional variational autoencoder (VAE) models are trained using the seed dataset for learning association between the traces and the logs. Synthetic traces and logs are generated using the multiple CVAE models while retaining the association between the traces and the logs for the synthetic traces and logs.

A carbon steel-concrete/cement mortar-stainless steel composite submarine pipeline belongs to the technical field of marine structure engineering. The composite submarine pipeline is formed by connecting several composite sub-pipelines arranged sequentially along an axial direction of the pipeline, each composite sub-pipeline has an identical structure and includes an outer carbon steel pipe and an inner stainless steel pipe each having a circular cross section and concentrically placed, concrete or cement mortar is filled between the outer carbon steel pipe and the inner stainless steel pipe to form a sandwiched structure with a circular ring-shaped cross section. Between two adjacent composite sub-pipelines, the welding line of the inner stainless steel pipelines is covered by the concrete/cement mortar, and the fatigue performance of the inner stainless steel pipes at the welding line can be improved effectively.

A computer identifies a first participant and a one or more additional participants associated with a collaboration through an electronic communication application that includes messaging content, identifies a first set of one or more keywords within the messaging content between the first participant and the one or more additional participants, retrieves a first set of historical information based at least in part on the first set of one or more keywords, the first participant and the one or more additional participants, generates a first instance of historical results that includes a multi-dimensional cube that graphs the first set of historical information with respect to the first set of one or more keywords, the first participant and the one or more additional participants, and a time frame, and provides the first instance of historical results to the first participant.

Email threads related to messaging content

Described is a technology by which topics corresponding to web pages are used in relevance ranking of those pages. Topics are extracted from each web page of a set of web pages that are found via a query. For example, text such as nouns may be extracted from the title, anchor texts and URL of a page, and used as the topics. The extracted topics from a page are used to compute a relevance score for that page based on an evaluation of that page's topics against the query. The pages are then ranked relative to one another based at least in part on the relevance score computed for each page, such as by determining a matching level for each page, ranking pages by each level, and ranking pages within each level. Also described is training a model to perform the relevance scoring and/or ranking.

Topics in relevance ranking model for web search

A network address mapping system is described. The network address mapping system can identify a set of Web pages, collects information from the Web pages indicating geographical locations ('geolocations'), and correlate the geolocations with the network addresses from which the identified Web pages are served. The collected information can be weighted based on various factors, such as its relative position in a Web page. The collected information can then be used to identify a geolocation. The network mapping system can deduce geolocations for portions of ranges of network addresses based on the score, and can infer geolocations for other portions based on the deduced geolocations. This mapping can then be stored in a database and provided as a geomapping service. The network address mapping system is able to map network addresses to geographical locations. Thereafter, when a user's client computing device accesses a Web server, the Web server can easily and accurately determine a geographical location by querying the database storing the mapping or a geomapping service.

A method and system for determining relevance of a document having text and images to a text string is provided. A scoring system identifies image text associated with an image of the document. The scoring system calculates an image score indicating relevance of the image text to the text string. The image score may be used in many applications, such as searching, summary generation, and document classification, image search, and image classification.

A learning system for a search ranking function model may include a computer program that iteratively refines the model using new queries and associated documents from an unlabeled training set. The unlabeled training set may include a set of queries for which the associated documents have not been labeled as 'relevant' or otherwise labeled. The new queries may be selected based on a similarity to and an accuracy of each neighbor from a labeled training set, such as a labeled validation set. Upon selection, the documents associated with the new queries may be labeled. The new queries and their associated documents may be accumulated into a labeled training set, such as a labeled training set, and a refined model may be learned based on the augmented labeled training set. The model may be iteratively refined until it is determined that the model is adequate.

Efficient search window storage schemes for motion estimation in video signal processing are disclosed. According to one embodiment, motion estimation is carried out as follows: allocating a ring buffer to store at least critical number of macro-blocks of luminance data from a reference frame on the motion estimator, establishing a rule to relate each storage unit of the ring buffer with each of the macro-blocks of the reference frame, initializing the ring buffer by reading in one less than the critical number of macro-blocks from the reference frame, when the macro-block is located next to a border of the reference frame, generating one or more added border macro-blocks and storing into the corresponding position of the ring buffer in accordance with the rule, constructing the search window from the macro-blocks stored in the ring buffer, and conducting motion estimation of the current macro-block of the current frame with the search window.

Method and apparatus for motion estimation in video signal decoding

Techniques pertaining to a circuit architecture capable of controlling a current source to a predefined precision are disclosed. According to one aspect of the present invention, an automatic trimming circuit is proposed to automatically trim a current generated from a current generator or circuit in accordance with a reference current. The automatic trimming circuit includes a comparator, an ADC and a register. The comparator that may be implemented as a subtractor finds a difference between a generated current and a reference current. The difference is then digitized to an n-bit precision. A digital representation of the difference is then kept in a register and used subsequently correct or modify the generated current to produce a precisely controlled current.
