Latest Patents

Kaiwei Li holds a patent for an "Electrocardiogram (ECG) signal detection and positioning method based on weakly supervised learning." This method employs a deep learning model that includes a multi-scale feature extraction module, a self-attention encoding module, and a classification and positioning module. The process begins with denoising and segmenting the original ECG signal to obtain a fixed-length pure ECG signal segment. The convolutionally-connected multi-scale feature extraction module incorporates a channel local attention (CLA) layer and utilizes a PReLU activation function to enhance local information extraction. The self-attention encoding module establishes a relationship between local and global features, while the classification and positioning module outputs the general location of any abnormal signals. A fusion module allows the model to map local predicted values onto global predicted values, with model parameters trained on a weakly annotated dataset.
