Abstract: Techniques are disclosed herein for managing ambiguous date mentions in natural language utterances in transforming natural language utterances to logical forms by encoding the uncertainties of the ambiguous date mentions and including the encoded uncertainties in the logical forms. In a training phase, training examples including natural language utterances, logical forms, and database schema information are automatically augmented and used to train a machine learning model to convert natural language utterances to logical form. In an inference phase, input database schema information is augmented and used by the trained machine learning model to convert an input natural language utterance to logical form.

Abstract: Techniques are disclosed herein for managing date-time intervals in transforming natural language utterances to logical forms by providing an enhanced grammar, a natural language utterance comprising a date-time interval, and database schema information to a machine learning model that has been trained to convert natural language utterances to logical forms; and using the machine learning model to convert the natural language utterance to an output logical form, wherein the output logical form comprises at least one of the date-time interval and an extraction function for extracting date-time information corresponding to the date-time interval from at least one date-time attribute of the database schema information.

Abstract: The present disclosure relates to manufacturing training data by leveraging an automated pipeline that manufactures visualization training datasets to train a machine learning model to convert a natural language utterance into meaning representation language logical form that includes one or more visualization actions. Aspects are directed towards accessing an original training dataset, a visualization query dataset, an incremental visualization dataset, a manipulation visualization dataset, or any combination thereof. One or more visualization training datasets are generated by: (i) modifying examples in the original training dataset, the visualization query dataset, or both to include visualization actions, (ii) generating examples, using the incremental visualization dataset, the manipulation visualization dataset, or both, that include visualization actions, or (iii) both (i) and (ii).

Abstract: Techniques are disclosed herein for transforming natural language conversations into a visual output. In one aspect, a computer-implement method includes generating an input string by concatenating a natural language utterance with a schema representation comprising a set of entities for visualization actions, generating, by a first encoder of a machine learning model, one or more embeddings of the input string, encoding, by a second encoder of the machine learning model, relations between elements in the schema representation and words in the natural language utterance based on the one or more embeddings, generating, by a grammar-based decoder of the machine learning model and based on the encoded relations and the one or more embeddings, an intermediate logical form that represents at least the query, the one or more visualization actions, or the combination thereof, and generating, based on the intermediate logical form, a command for a computing system.

Abstract: A human-powered positive-displacement single dual-action cylinder treadle pump for use in pumping and distributing water from wells and other water sources, as well as methods of manufacturing and operating such a pump. The pump offers rural farmers a portable device for pumping water for use in irrigating fields and crops that is powerful, low-cost, modular and portable. The modularity of the pump allows for easy access to any of the components of the pump should they require maintenance, repair or replacement.

Abstract: A sanding tool includes a handle assembly and a head assembly having a sanding member. The sanding tool also includes at least one pivot member that pivotably couples the handle assembly and the head assembly such that the head assembly is pivotable about a plurality of different axes relative to the handle assembly.

Abstract: Various embodiments of the present invention are directed to a system, method, and apparatus for offering products and services based, at least in part, on a continually updating analysis of user accounts held by commercial enterprises such as banks, credit card companies, media service providers, insurance companies, and other institutions that maintain user accounts that are subject to periodic transactions. One embodiment is directed to a system comprising a processor and a memory for storing data coupled to the processor, wherein the memory includes a user account comprising user data, user account data, and relationship data. The processor is configured for calculating a risk score based at least in part on the user data, user account data, or relationship data. The processor is further configured for outputting a set of products or services based at least in part on the risk score.

Abstract: A method for marketing a product to one or more customers includes retrieving a profitability score for the customer from a customer database. The product is selectively marketed to the one or more customers based on the profitability score. In a particular embodiment, a plurality of products can be bundled together to generate a bundle of products. The bundle of products can be selectively marketed to the customer. Further, the profitability score for the customer can be determined by determining a billed revenue for the customer over a predetermined time period and determining a collected revenue for the customer over the predetermined time period. Thereafter, the collected revenue is divided by the billed revenue to yield a percentage paid. Additionally, the percentage paid can be scaled to an integer between 1 and 999 to yield the profitability score.

Abstract: Content is distributed from a source to a sink only if the sink is within a predetermined geographic locality. In one embodiment, a signature request is sent to the sink. The sink obtains an actual signature compares it to the requested signature, and if the requested signature and the actual signature resemble each other sufficiently closely, then the content is sent to the sink The signature is compiled from parameters obtained from appropriate parameter detectors. The parameter detectors generate, detect and monitor various signals required for determining the locality of the sink.

Abstract: Off-site factory built structure employs a chassis including two interior longitudinal beam members joined at their ends to a perimeter structure. A floor system is integrated within the chassis perimeter. A ledger member is fixed to the inner surface of each longitudinal perimeter member so that a top surface lies in a plane coincident with top surfaces of the interior longitudinal beams. Lateral members are coupled to the tops of the interior longitudinal beams and to the top of the ledger members. The lateral members include secondary stiffening members such as C-channel members, metal Z-channel members, or other metal members of similar structural capacity, spaced apart from each other by a maximum distance S, related to the width of the floor system W, by the equation: S 12?½W.

Abstract: Disclosed are systems and methods for de-skewing media when using an automatic media feeder comprising a registration guide and a registration tab disposed to cooperate with the registration guide in providing de-skewing of media when an edge of the media passes over the registration tab and is deflected thereby toward the registration guide.
