Abstract: Accuracy of transcript is of foremost importance in Automatic Speech Recognition (ASR). State of the art system mostly rely on spelling correction based contextual improvement in ASR, which is generally a static vocabulary based biasing approach. Embodiments of the present disclosure provide a method and system for visual context aware ASR. The method provides biasing using shallow fusion biasing approach with a modified beam search decoding technique, which introduces a non-greedy pruning strategy to allow biasing at the sub-word level. The biasing algorithm brings in the visual context of the robot to the speech recognizer based on a dynamic biasing vocabulary, improving the transcription accuracy. The dynamic biasing vocabulary, comprising objects in a current environment accompanied by their self and relational attributes, is generated using a bias prediction network that explicitly adds label to objects, which are detected and captioned via a state of the art dense image captioning network.

Abstract: A triboelectric generator comprises a first body moveable relative to a second body. Power generation modules are disposed on the first body and one or more actuating elements are disposed on the second body. Each power generation module is electrically connected to a common output and comprises material capable of generating electrical power through the triboelectric effect when contacting another surface. The power generation modules and one or more actuating elements are arranged on the bodies such that relative movement of the bodies causes the one or more actuating elements to come into contact with the power generation modules, wherein the contact causes the material of that power generation module to be brought into contact with said other surface to generate electrical power. The power generation modules may supply electrical power to the common output at different times, providing a more continuous supply of electrical power from the common output.

Abstract: This disclosure addresses the unresolved problems of tackling object disambiguation task for an embodied agent. The embodiments of present disclosure provide a method and system for disambiguation of referred objects for embodied agents. With a phrase-to-graph network disclosed in the system of the present disclosure, any natural language object description indicating the object disambiguation task can be converted into a semantic graph representation. This not only provides a formal representation of the referred object and object instances but also helps to find an ambiguity in disambiguating the referred object using a real-time multi-view aggregation algorithm. The real-time multi-view aggregation algorithm processes multiple observations from an environment and finds the unique instances of the referred object.

Abstract: A system for identifying items based on aggregated metadata obtains images of an item. The system extracts a set of features from images of the item. The system identifies a first value of a first feature associated with a first image of the item. The system identifies a second value of the first feature associated with a second image of the item. The system aggregates the first value and the second value. The system associates the item to the aggregated first value and the second value, where the aggregated first value and the second value represent the first feature of the item. The system adds a new entry for each image of the item to a training dataset associated with an item identification model.

The processor is to further permute and pack remaining neurons or weights of the pruned machine learning model to reduce an amount of ciphertext computation under a selected constraint.

Abstract: The present disclosure relates to systems, non-transitory computer readable media, and methods for detecting and providing a digital notification of whether a ridership error exists. For instance, a ridership error detection system identifies a transportation match between a requestor device and a provider device. The ridership error detection system determines one or more sets of provider-requestor consistency signals from the requestor device and the provider device across ride stages. For instance, the ridership error detection system analyzes location signals, IMU signals, audio signals, local wireless signals indicating distances between the requestor device and the provider device, and other signals to determine whether a ridership error exists. The ridership error detection system provides digital notifications to the provider device and the requestor device based on the ridership error determination.

The second slave stage generates an inverted output signal during the rising edge of the clock cycle. The output signal and the inverted output signal are available concurrently.

Abstract: A network device may receive IPv6 fragments of a flow. Source and/or destination port information may be encoded into an upper sixteen bits of an identification number of an IPv6 fragment header of each of the IPv6 fragments. The network device may extract the source and/or destination port information from the IPv6 fragments, and may perform a spoof check of the IPv6 fragments. The network device may drop any of the IPv6 fragments that fail the spoof check, to generate remaining IPv6 fragments, and may translate the remaining IPv6 fragments into IPv4 fragments based on the source and/or destination port information. The network device may forward the IPv4 fragments toward an IPv4 cloud network.

Abstract: Techniques and devices for expressing multicast groups using Weave traits are described for generating a multicast address in which a wireless network device receives an application group identifier and hashes the application group identifier to generate a group identifier. The wireless network device concatenates a global identifier and a Weave fabric identifier, inserts the concatenated global identifier and the Weave fabric identifier into a network prefix field of a destination address and inserts the group identifier into a group identifier field of the destination address. The wireless network device sets the value of a plen field of the destination address to a value that indicates a length of the Weave fabric identifier and inserts the destination address into an Internet Protocol version 6 data packet.

The gearbox includes a centrally located sun gear, two or more planet gears circumscribing the sun gear, and a ring gear circumscribing the plurality of planet gears. The gearbox is configured such that the sun gear is drivingly coupled to the first rotating component, such that rotation of the sun gear causes rotation of each planet gear, and such that the ring gear rotates relative to the plurality of planet gears. The gearbox includes one or more shape memory alloy dampers provided in association with the sun gear, the ring gear, and/or the plurality of planet gears. The shape memory alloy damper(s) is configured in order to reduce vibrations transferred through the epicyclic gearbox to the frame, the first rotating component, and/or the second rotating component.
