Abstract: There is provided a computer-implemented method for updating a search distribution of an evolutionary strategies optimizer using an optimizer neural network comprising one or more attention blocks. The method comprises receiving a plurality of candidate solutions, one or more parameters defining the search distribution that the plurality of candidate solutions are sampled from, and fitness score data indicating a fitness of each respective candidate solution of the plurality of candidate solutions. The method further comprises processing, by the one or more attention neural network blocks, the fitness score data using an attention mechanism to generate respective recombination weights corresponding to each respective candidate solution. The method further comprises updating the one or more parameters defining the search distribution based upon the recombination weights applied to the plurality of candidate solutions.

Abstract: In one aspect there is provided a method for training a neural network system by reinforcement learning. The neural network system may be configured to receive an input observation characterizing a state of an environment interacted with by an agent and to select and output an action in accordance with a policy aiming to satisfy an objective. The method may comprise obtaining a policy set comprising one or more policies for satisfying the objective and determining a new policy based on the one or more policies. The determining may include one or more optimization steps that aim to maximize a diversity of the new policy relative to the policy set under the condition that the new policy satisfies a minimum performance criterion based on an expected return that would be obtained by following the new policy.

Abstract: A process for document processing (e.g., automated package splitting) may involve producing, for each document page of an ordered plurality of document pages, an image of the document page and a representation of text from the document page; generating, for each document page of the ordered plurality, and based on the image of the document page and the representation of text from the document page, an embedding of the document page; and generating, for each document page among a subset of the ordered plurality, a label for the document page that indicates whether the document page is a document first page, based on the embedding of the document page, the embedding of each of at least one document page that precedes the document page in the ordered plurality, and the embedding of each of at least one document page that follows the document page in the ordered plurality.

Abstract: The present disclosure provides systems and methods for enhancing the performance of permeable antennas. Further, the parallel solenoid feed system disclosed herein may be used to reduce or eliminate significant phase delays in antennas, which may lead to destructive interference. Moreover, use of the parallel solenoid feed in an antenna eliminates the need for multiple feeds, complicated feed networks, and elaborate matching circuits. Using the parallel solenoid feed in circular magnetic antennas may enhance the performance of the antenna through maintaining the flux. Finally, many adjustable parameters for further tuning and/or optimizing the performance of particular antenna design have been identified herein, which may allow those skilled in the art to utilize known systems, such as full wave simulation software, to determine the desired final design for an antenna utilizing a parallel solenoid feed.

Abstract: Disclosed is an improved method and apparatus to calibrate a material characterization system. The method and apparatus are operative to set up multiple configurations for measuring and recording a specific characteristic response of the system for each configuration, using electromagnetic waves. The apparatus is designed to enable the system to measure and record the position of a reference material and a set of calibration data for such reference material, while positioned at locations that correspond to a range of possible thicknesses or fluttering during measurements of a sample that the system is capable of characterizing. As a result, a sample under test having a specific thickness and measured at a particular position can be readily calibrated analytically or by using reference data previously recorded with the same set up.

Abstract: Disclosed is a touchscreen antenna system and a method of designing a touchscreen antenna system. The system and method are operative to integrate an antenna with one or more touchscreen components to render a compact and effective system and to provide a more robust operation. The system is configured such that an antenna element, comprising a radiating component or an antenna feeding portion, is electromagnetically coupled to a touchscreen element, including a touch sensor, a touch sensor line, and other active or passive elements of a touchscreen module. Accordingly, the system is capable to mitigate adverse effects, when operating in an environment or under conditions that may affect other systems or be susceptible to being affected by other sources, by designing antenna and touchscreen elements as an integrated unit. Additionally, the system and method provide an enhanced antenna system performance by incorporating touchscreen elements as part of the antenna design.
