Abstract

A method, apparatus, and computer-readable storage medium for predicting the affinity of an antibody sequence for an antigen sequence. The method includes obtaining antigen sequence information and antibody sequence information comprising light chain and heavy chain sequence information. Sequence features are extracted from the antigen sequence, light chain sequence, and heavy chain sequence. These extracted features are fused to obtain fused sequence features, which are then processed using a fully connected neural network. The processing determines an affinity detection result representing the affinity of the antibody sequence for the antigen sequence. This computational approach enables efficient prediction of antibody-antigen binding affinities for applications in therapeutic antibody development and immunological research.

Abstract

An electronic device plays a target video on a first application. The device detects a screen projection triggering event when a playing progress of the target video in the first page reaches a first progress, In response to the detecting, the device causes the target video to project onto a target screen projection device so that the target video continues to be played in a second page of the target screen projection device from the first progress and receives one or more updates on the playing progress of the target video from the target screen projection device. In response to detecting a screen projection stopping triggering event, the electronic device resumes playing the target video in the first page of the first APP of the electronic device from a last update on the playing progress of the target video received from the target screen projection device.

Abstract

A data encoding and decoding system, method, and apparatus for efficient feature data processing. The method obtains auxiliary encoding information of feature data and determines scale parameter values corresponding to feature elements. After quantizing these values to integers, the method selects a subset of scale parameter quantization values exceeding a preset threshold. Feature elements corresponding to these selected values are extracted from the feature data and undergo entropy encoding based on their corresponding quantization values. For unencoded feature elements, the method determines appropriate replacement elements. The process combines entropy encoded elements with replacement elements to create an efficient encoded data stream, which can later be decoded through a reverse process. This selective encoding approach significantly reduces data size while maintaining essential information for accurate reconstruction.

Abstract

This application relates to an audio processing method, an electronic device, and a storage medium. The method includes: displaying a target audio clip and corresponding target text information having a mapping relationship between a location of an audio segment in the target audio clip and a location of text information in the corresponding target text information; receiving, a selection of a location in the corresponding target text information as a to-be-processed text location; matching a to-be-processed audio location of an audio segment that has the mapping relationship with the to-be-processed text location; and processing the target audio at the to-be-processed audio location to generate an updated target audio clip, and updating the corresponding target text information at the to-be-processed text location to generate updated target text information; and displaying the updated target audio clip and the updated target text information.

Abstract

A data processing method and apparatus, and an electronic device are provided. The method includes inputting the multi-modal data into a large natural language model, and performing the following operations based on the large natural language model: performing feature extraction to obtain an element feature and a position feature, characterizing a character position of each element in the multi-modal data; fusing the element feature and the position feature to obtain a fused feature; obtaining a multi-modal data category and a confidence score corresponding to the multi-modal data category based on the fused feature. The large natural language model is trained by inputting auxiliary training information during training of the large natural language model, so that the large natural language model is configured to obtain the confidence score after the training is completed, and presenting corresponding feedback information based on the multi-modal data category and the confidence score.

Abstract

Some aspects of the disclosure provide a method of point cloud decoding by a decoder. In some examples, a bitstream of coded information of a point cloud is received. According to the coded information, respective geometry information of a plurality of first nodes in the point cloud are obtained. A geometry mode of a current node is determined according to the respective geometry information of the plurality of first nodes. The current node is a current to-be-decoded node in the point cloud. The plurality of first nodes include at least one of: a reference node of the current node, a child node of the reference node, a decoded child node of the current node, and/or a to-be-decoded child node of the current node. Apparatus and non-transitory computer-readable storage medium counterpart embodiments are also contemplated.

Abstract

The present application relates to a task instruction construction method and apparatus, a task processing method and apparatus, a computer device, a computer readable storage medium, and a computer program product. The task instruction construction method comprises: acquiring task information of a target task, and an instruction data set comprising a plurality of pieces of instruction information (S302); performing semantic analysis on the task information to determine a task type and a task requirement of the target task (S304); using query information matching the task type to guide a large model to select, from the instruction data set, candidate instructions matching the task type (S306); and determining, from among the candidate instructions, a task instruction satisfying the task requirement (S308), wherein the task instruction is used for guiding the large model to execute the target task. The method can improve the working efficiency during task instruction construction.
