20150186938 | SEARCH SERVICE ADVERTISEMENT SELECTION - Methods, computer systems, and computer storage media are provided for evaluating information retrieval (IR) such as search query results (including advertisements) by a machine learning scorer. In an embodiment, a set of features is derived from a query and a machine learning algorithm is applied to construct a linear model of (query, ads) for scoring by maximizing a relevance metric. In an embodiment, the machine learned scorer is adapted for use with WAND algorithm based ad selection. | 07-02-2015 |
20150278200 | Convolutional Latent Semantic Models and their Applications - Functionality is described herein for transforming first and second symbolic linguistic items into respective first and second continuous-valued concept vectors, using a deep learning model, such as a convolutional latent semantic model. The model is designed to capture both the local and global linguistic contexts of the linguistic items. The functionality then compares the first concept vector with the second concept vector to produce a similarity measure. More specifically, the similarity measure expresses the closeness between the first and second linguistic items in a high-level semantic space. In one case, the first linguistic item corresponds to a query, and the second linguistic item may correspond to a phrase, or a document, or a keyword, or an ad, etc. In one implementation, the convolutional latent semantic model is produced in a training phase based on click-through data. | 10-01-2015 |
20160042296 | Generating and Using a Knowledge-Enhanced Model - Functionality is described herein for generating a model on the basis of user-behavioral data and knowledge data. In one case, the user-behavioral data identifies queries submitted by users, together with selections made by the users in response to the queries. The knowledge data represents relationships among linguistic items, as expressed by one or more structured knowledge resources. The functionality leverages the knowledge data to supply information regarding semantic relationships which may not be adequately captured by the user-behavioral data, to thereby produce a more robust and accurate model (compared to a model produced on the basis of only user-behavioral data). Functionality is also described herein for applying the model, once trained. In one case, the model may correspond to a deep learning model. | 02-11-2016 |

20140355918 | ROTARY SUPPORT INCLUDING BEARINGS - A rotary support, comprising: a bearing inner race; a bearing outer race including a plurality of axially disposed through holes; a first plurality of rolling elements installed between the bearing inner race and the bearing outer race, and arranged to retain the bearing inner race and the bearing outer race in rolling engagement; and an outer ring radially surrounding and fixed to an outer portion of the bearing inner race and disposed axially opposite to the bearing outer race; wherein the outer ring includes a plurality of axially penetrating mounting holes; and wherein the bearing outer race through holes are axially aligned with the outer ring mounting holes. | 12-04-2014 |
20150345549 | BEARING ASSEMBLY - A bearing assembly, including: a housing having a through hole; first and second bearings coaxially set in the through hole, the first bearing is located at one end and the second bearing is located at an other end of the through hole, and both the first and second bearings include inner and outer rings. A first shaft sleeve is set between the first and the second bearing along an axial direction. An end cap located at the other end of the through hole, is connected with the housing and adapted to rotate relatively to the housing. The first bearing is located between the end cap and the first shaft sleeve along the axial direction. Accordingly, the end cap can be connected with the housing for preventing the end cap from falling out of the housing, thus the bearing assembly is configured into an integrated piece for transportation and usage. | 12-03-2015 |
