Abstract: Systems and methods are provided for personalizing new song suggestions for a user. A plurality of users provides thumbs up and thumbs down ratings for a pair of songs (song A and B). A first aggregate rating for song B is calculated based on ratings given to song A by all of the users that gave a like rating to song A. Similarly, a second aggregate rating is calculated for song B based on ratings given to song B by all users that gave a dislike rating to song A. Then a user that has not previously rated song B, supplies a rating for song A. A prediction is performed of how the user will rate song B based on the user's rating of song A. For example, the first aggregate rating for song B is used if the user rated song A positively.

Abstract: Methods, information handling systems and computer readable media are disclosed for a contextual image-based search. In one embodiment, a method includes receiving, at a computer implemented system for searching a knowledge base, an image submitted by a user of the system. The method continues with obtaining a classification label corresponding to the image, checking a context module database for the presence of a follow-up question associated with the classification label, and generating search term information for searching of the knowledge base, where the search term information comprises the classification label. If a follow-up question associated with the classification label is found, an embodiment further includes presenting the follow-up question to the user of the system, receiving from the user an answer to the follow-up question, modifying the search term information to include the answer, and checking the context module database for an additional follow-up question associated with the answer.

Abstract: Techniques are described for automatically extracting items from a user's browse history on one or more e-commerce websites, and automatically searching other e-commerce websites and sources for offers (including coupons, deals, and/or promotions) for those items and/or related items and/or stores. Such automated techniques allow users to gain the benefit of online offers from various sources, without having to go through the effort of manually searching for such offers. Instead, the system and method automatically locate such offers based on the user's browse history, without requiring any action to be taken on the part of the user.

Abstract: An interface device may provide a first wireless network and a second wireless network in a user's premise. The interface device may encourage some user devices to connect to the second wireless network without controlling the user devices. For example, the interface device may receive a request from a device to access its first wireless network. The interface device may then determine whether the device is a premise device by, for example, searching a database of device registration information. The interface device may determine that the device is a premise device and deny the request to access the first wireless network. The device may then be available to access the second wireless network.

Abstract: Aspects of the technology described herein allocate limited computing resources, such as available bandwidth and battery power, to transferring the most urgent and important data from a client device to an online service. Client devices have enormous amounts of information about the user's activities that could be communicated to the service at any given time. However, the wireless transfer of information uses available battery power and can consume a user's data plan. The technology described herein uses a model to determine how often information should be sent to a service. The model can also determine what information to send. Different models can be implemented in different scenarios. The different models can include different weighting that will produce different decisions given the same inputs.

Abstract: Methods and systems are provided for controlling an airflow to an engine via a primary air induction pathway or a secondary air induction pathway, where the secondary air induction pathway routes the airflow to the engine via a deployable snorkel system. Thus, in one example, a method comprises routing the airflow to the engine solely via the primary air induction pathway by commanding open a first air inlet valve and commanding closed a second air inlet valve, and responsive to a request to switch the routing, commanding closed the first air inlet valve and commanding open the second air inlet valve. In this way, the snorkel system may selectively be used in response to requests from a vehicle operator.

Abstract: A multi-layer cap shingle for installation along a ridge, hip, or rake of a roof includes a forward exposure area and a rear headlap area. The multi-layer cap shingle includes at least two layers of shingle material, a top layer and a bottom layer each having opposed edges. The layers are bonded together with patches of lamination adhesive adjacent their opposed edges. The bottom layer is configured with a deformation-absorbing mechanism such as a pair of slots extending from a forward edge reawardly inboard of the lamination adhesive patches. When the multi-layer cap shingle is bent over a roof ridge, the slots of the bottom layer of shingle material narrow in width to account for the fact that the bottom layer must bend around an arc of slightly smaller radius than the top layer of shingle material.

Abstract: Control of a prompt for a credential to unlock a computer-readable storage device is provided. Some embodiments permit identifying a component that encrypted the computer-readable storage device and, depending on the identified component, prompting for such a credential. One embodiment can determine that a firmware encrypted the computer-readable storage device and can prompt for a password, for example, to unlock the computer-readable storage device during a boot-up process performed by the firmware. Other embodiments can determine that an operating system encrypted the computer-readable storage device, and can avoid the presentation of a prompt for a password, for example, during a boot-up process performed by the firmware. The computer-readable storage device can be a self-encrypting drive (SED) or another type of disk drive.

Abstract: The present disclosure provides a method of determining a relative decrease in catalytic efficacy of a catalyst in a test sample of a catalyst solution with unknown catalytic activity. The method includes (a) mixing the test sample with a test solvent to form a test mixture and (b) measuring the increase in the temperature of the test mixture at predetermined time intervals immediately after forming the test mixture. A predetermined feature is used to determine both a test value in the increase in temperature measured in (b) and a control value in a known increase in temperature of a control mixture of the test solvent with a control sample of a control catalyst solution. The relative decrease in catalytic efficacy of the catalyst in the test sample having the unknown catalytic activity is then determined from: Relative Decrease in Catalytic Efficacy=Control Value?Test Value/Control Value.

Abstract: Some embodiments described herein cover a machine learning architecture with a separated perception subsystem and application subsystem. These subsystems can be co-trained. In one example embodiment, a data item is received and information from the data item is processed by a first node to generate a sparse feature vector. A second node processes the sparse feature vector to determine an output. A relevancy rating associated with the output is determined. A determination is made as to whether to update the first node based on update criteria associated with the first node, wherein the update criteria comprise a relevancy criterion and a novelty criterion. The second node is updated based on the relevancy rating.
