145 results about "Dummy data" patented technology

In Informatics, dummy data is benign information that does not contain any useful data, but serves to reserve space where real data is nominally present. Dummy data can be used as a placeholder for both testing and operational purposes. For testing, dummy data can also be used as stubs or pad to avoid software testing issues by ensuring that all variables and data fields are occupied. In operational use, dummy data may be transmitted for OPSEC purposes. Dummy data must be rigorously evaluated and documented to ensure that it does not cause unintended effects.

A method for joint classification of hyperspectral images and lidar data

This invention relates to the field of deep learning technology, and in particular provides a joint classification method for hyperspectral images and LiDAR data. The method first extracts multi-scale features from multimodal data by decoupling a three-branch encoder. Then, a self-designed feature fusion module performs attention-guided cross-modal fusion on three initial features at the same scale, resulting in three multimodal fused features at different scales. The deepest fused feature is input to a weight-shared decoder, where pseudo-data is obtained through a reconstruction task. A structure consistency-aware discriminator identifies real data from pseudo-data and returns a discrimination loss, thereby updating the encoder parameters and iterating until optimal. Finally, the fused features at the three scales obtained based on the optimal parameters are input into a multi-level feature fusion classifier to complete the classification. This method effectively improves classification accuracy and achieves adaptive fusion and enhancement of multimodal features.
