Abstract: The present disclosure relates to a passive outlier-tolerant and active outlier-tolerant learning method with abnormal samples and a system thereof. The method includes the following steps: (1) judging the distribution of abnormal samples in a train set, and calling a corresponding outlier-tolerant algorithm based on the distribution to carry out feature learning on the sample feature quantity in the train set to obtain an outlier-tolerant learning result; (2) training an initial learning model by using the outlier-tolerant learning result to obtain an intermediate learning model; (3) processing the test set by a preset outlier-correction algorithm to obtain an outlier-corrected test set; (4) testing the intermediate learning model using the outlier-corrected test set to obtain a final learning model. The scheme of the present disclosure can improve the passive outlier tolerance and active outlier tolerance of a machine learning process to abnormal samples.

Abstract: A parachute-designed biodegradable occluder is provided. The parachute-designed biodegradable occluder is with a proximal end adjacent to a human body and a distal end far away from the human body. The parachute-designed biodegradable occluder includes an occluder stent internally provided with a baffle film, and a shapeable ring with changeable states. The occluder stent, the baffle film and the shapeable ring are respectively made of polymer materials being degradable in biological tissues. The occluder is made of a biodegradable polymer material, which is degradable or absorbable by human tissues after being implanted for a period of time to make a defect site composed of human tissues, realizing occlusion without foreign matter. The occlusion effect is particularly significant for children.
