20130151441 | MULTI-TASK LEARNING USING BAYESIAN MODEL WITH ENFORCED SPARSITY AND LEVERAGING OF TASK CORRELATIONS - Multi-task regression or classification includes optimizing parameters of a Bayesian model representing relationships between D features and P tasks, where D≧1 and P≧1, respective to training data comprising sets of values for the D features annotated with values for the P tasks. The Bayesian model includes a matrix-variate prior having features and tasks dimensions of dimensionality D and P respectively. The matrix-variate prior is partitioned into a plurality of blocks, and the optimizing of parameters of the Bayesian model includes inferring prior distributions for the blocks of the matrix-variate prior that induce sparseness of the plurality of blocks. Values of the P tasks are predicted for a set of input values for the D features using the optimized Bayesian model. The optimizing also includes decomposing the matrix-variate prior into a product of matrices including a matrix of reduced rank in the tasks dimension that encodes correlations between tasks. | 06-13-2013 |
20130226839 | ROBUST BAYESIAN MATRIX FACTORIZATION AND RECOMMENDER SYSTEMS USING SAME - In a recommender method, Bayesian Matrix Factorization (BMF) is performed on a matrix having user and item dimensions and matrix elements containing user ratings for items made by users in order to train a probabilistic collaborative filtering model. A recommendation is generated for a user using the probabilistic collaborative filtering model. The recommendation may comprise a predicted item rating, or an identification of one or more recommended items. The recommender method is suitably performed by an electronic data processing device. The BMF may employ non-Gaussian priors, such as Student-t priors. The BMF may additionally or alternatively employ a heteroscedastic noise model comprising priors that include (1) a row dependent variance component that depends upon the matrix row and (2) a column dependent variance component that depends upon the matrix column. | 08-29-2013 |
20140156231 | PROBABILISTIC RELATIONAL DATA ANALYSIS - A multi-relational data set is represented by a probabilistic multi-relational data model in which each entity of the multi-relational data set is represented by a D-dimensional latent feature vector. The probabilistic multi-relational data model is trained using a collection of observations of relations between entities of the multi-relational data set. The collection of observations includes observations of at least two different relation types. A prediction is generated for an observation of a relation between two or more entities of the multi-relational data set based on a dot product of the optimized D-dimensional latent feature vectors representing the two or more entities. The training may comprise optimizing the D-dimensional latent feature vectors to maximize likelihood of the collection of observations, for example by Bayesian inference performed using Gibbs sampling. | 06-05-2014 |
20150019912 | ERROR PREDICTION WITH PARTIAL FEEDBACK - A method for performing data processing through a pipeline of components includes receiving a set of training observations, each including partial user feedback relating to error in data output by the pipeline for respective input data. Some pipeline components commit errors for at least some of the input data, contributing to an error in the respective output data. A prediction model models a probability of a pipeline component committing an error, given input data. Model parameters are learned using the training observations. For a new observation which includes input data and, optionally, partial user feedback indicating that an error has occurred in processing the new input data, without specifying which pipeline component(s) contributed to the observed error in the output data, a prediction is made as to which of the pipeline components contributed to the error in the output (if any). | 01-15-2015 |

20140300115 | HIDDEN FLUSH OUTSIDE HANDLE - An outside handle of a vehicle that releases a door latch, including a slot that includes a rotatable flap that sits flush against an outer panel of the vehicle in a closed position. The rotation of the flap provides an opening to an inside of the handle in an open position. The handle includes a rotating lever behind the outer panel, and a lock rod attached to the rotating lever. Downward rotation of the lever moves the rod downward, and the downward motion of the rod then triggers the latch. | 10-09-2014 |

20150315812 | FLUSH MOUNTED VEHICLE HANDLE - An outside handle of a door of a vehicle that opens a latch, including a rotatable flap that sits flush against an outer panel of the vehicle in a closed position and that provides an opening to an interior of the handle in an open position, and a rotating lever behind the outer panel, movement of the lever opening the latch of the door. The handle is arranged such that the flap rotates to the open position when the door is unlocked and rotates to the closed position when the door is locked. | 11-05-2015 |

20120218483 | VARIABLE POWER OPTICAL ELEMENT - A variable power optical element is divided into cells which contain two liquid crystals mixed according to different proportions. The proportion of one of the liquid crystals in each cell increases on the basis of the radial distance between a central point of the optical element and said cell. An appropriate selection of the two liquid crystals results in a higher variation of the optical power between two control states of said optical element. More particularly, the optical element may consist of an ophthalmic lens which changes between a convergent lens state and a divergent lens state. | 08-30-2012 |

20120307340 | TRANSPARENT ELECTROCHROMIC SYSTEMS WITH A PLURALITY OF POLARISATION ELECTRODES - The invention relates to transparent electrochromic systems which each include one pair of supply electrodes and at least one pair of polarisation electrodes. The polarisation electrodes prevent a reaction of mutual neutralisation of the electroactive substances of the systems from causing unnecessary consumption of electric current. Said electrodes also prevent a neutralisation reaction from limiting a lower value of light transmission of the systems. For this purpose, the polarisation electrodes produce an electric field inside the systems, which attracts the electroactive substances that have already reacted with the supply electrodes to different areas. | 12-06-2012 |
20150176202 | SELECTIVE TINTING METHOD - A selective dyeing method is used for dyeing a substrate, selectively within a first exposed surface portion of said substrate. For this purpose, the substrate consists of a material that is impervious to a dye with the exception of the first portion of the exposed surface. In particular, the impervious material can form a layer which covers a base portion of the substrate in a second portion of the exposed surface. The substrate is heated such that the dye penetrates a pervious material which constitutes the first portion of the exposed surface. The method is particularly useful for eliminating light diffused by the walls of a multilayer structure which is supported by means of ocular glass. | 06-25-2015 |
