With the advance of artificial intelligence algorithms, their applications in the medical field have become increasingly diverse, such as lymph node metastasis detection, diabetic retinopathy detection, skin cancer detection and pneumonia detection, etc., The research team of Artificial Intelligence of Things in a Medical Center has successively used ECG to predict serum potassium and myocardial infarction via unsupervised transfer feature learning and achieved good results. The above-mentioned research is not only published as academic research, but is further implemented and applied in the medical field, confirming the artificial intelligence of medical care.
