This invention belongs to the interdisciplinary field of biomedical engineering and artificial intelligence-assisted diagnosis. It discloses a training method for a SERS spectral classification prediction model and its application. The disclosed SERS spectral classification prediction model training method combines CatBoost feature selection and deep learning. First, surface-enhanced Raman spectroscopy (SERS) data of serum from different categories of subjects is collected. After baseline removal, filtering, and normalization preprocessing, CatBoost gradient boosting algorithm is used to evaluate feature importance, considering the high-dimensional redundancy of the spectral data, and to select a subset of discrete feature bands containing key biomarker information. This feature subset is then input into a one-dimensional convolutional neural network model for training. The model constructed by this invention possesses deep feature mining capabilities, and the biological interpretability of the decisions is verified through SHAP analysis. It effectively solves the problems of large spectral noise interference and difficulty in extracting weak pathological features in traditional methods. For example, it can be used for the auxiliary diagnosis of coronary heart disease, achieving non-invasive, rapid, and high-precision classification and diagnosis of coronary heart disease and its subtypes.

The utility model discloses a washing machine safety control electromagnetic lock, and particularly relates to the technical field of control electromagnetic locks, the washing machine safety control electromagnetic lock comprises a lower cover, the top of the lower cover is fixedly connected with an upper cover, one side of the lower cover and one side of the upper cover are provided with a spring bolt in a sliding mode, one side of the spring bolt is fixedly provided with a plurality of contacts, and one side of the spring bolt is provided with a limiting mechanism in a sliding mode. The limiting mechanism is fixedly arranged between the lower cover and the upper cover, the coil frame is fixedly arranged on one side of the limiting mechanism between the lower cover and the upper cover, the enameled coil is wound on the coil frame, the fixed iron core is installed on the rear side of the coil frame to increase magnetic attraction force, one end of the movable lock cylinder penetrates in from one side of the compression spring and is arranged on the spring bolt in a sleeving mode, and the movable lock cylinder is locked. When the electromagnetic coil is powered on, the spring bolt is driven to move due to the magnetic attraction force of the coil, so that the working voltage is low, the power consumption is low, high-frequency electromagnetic sound and radiation are avoided, the heating speed is low, the service life is long, the coil is effectively prevented from bursting, and the safety during use is improved.
