  • Publication number: 20260245272
    Abstract: The present disclosure relates to systems, non-transitory computer-readable media, and methods for generating a synthesized digital image based on reference digital images and a case prompt. In one or more embodiments, the disclosed systems determine one or more reference digital images and a case prompt including a natural language description of a target digital image in response to a request. The disclosed systems utilize an encoder neural network to generate image patch embeddings from the one or more reference digital images with one or more role indicators for the one or more reference digital images and noise patch embeddings from latent noise. The disclosed systems combine the image patch embeddings, the noise patch embeddings, and a case prompt encoding to form a composite embedding. The disclosed systems utilize a diffusion neural network to generate a synthesized digital image based on the composite embeddings and the one or more role indicators.

  • Patent number: 12711525
    Abstract: A cost-focused determination of whether to deliver an electronic advertisement or notice to a particular user can be made through a cumulative consideration of the predicted return on investment over each of a plurality of electronic channels. A plurality of channel-specific budget values are calculated for the user, one for each channel, each setting an upper spending limit for advertisement to the user over that channel based on the user's information and their activity on the channel. A global budget is calculated for the user using a weighted aggregation of the channel-specific values, information about the user and their activity with the advertiser, and consideration of “overlap” effects of advertising to the same user on several channels. When managing whether to deliver an advertisement over a channel, if the channel-specific value is lower than the global budget, the advertisement is delivered, and the global budget is decreased by a complementary amount.

  • Patent number: 12688237
    Abstract: Listwise autocomplete ranking with position debias is described. A computing system can receive a user input indicative of a portion of a search query. The computing system can receive a set of candidate queries for an autocomplete list based on the portion of the search query. The computing system can generate a respective ranking score for each candidate query of the set of candidate queries by calculating, for each candidate query of the set of candidate queries, a respective click probability prediction using a position debiased listwise click-through rate (CTR) prediction model, and calculating, for each candidate query of the set of candidate queries, a respective reward per search. The computing system can order the set of candidate queries according to the respective ranking scores. The computing system can output at least one of the candidate queries based on the ordered set of candidate queries.

  • Publication number: 20260204920
    Abstract: A method for controlling switching of a power device from off-grid operation to grid-connected operation is provided. When a power grid is powered on, a given angular frequency difference required by a voltage-controlled oscillator when a phase of an off-grid output voltage is corrected to a phase of a power grid voltage is directly calculated based on an output phase of the power device in an off-grid mode and a preset angular frequency, and an integral result of a PI controller of a phase-locked loop (PLL) is initially assigned based on the given angular frequency difference. Then the PLL is controlled to start operating, an oscillation angular frequency of the voltage-controlled oscillator is configured based on an output of the PI controller and a preset power grid frequency, and the power device is controlled to connect to the power grid.
