Abstract: For a set in sets of candidate factors, a classification model is trained to predict a computer problem possibility, an accuracy score of the classification model is determined based on model validation, and factor weights of the candidate factors in the set are adjusted based on the accuracy score. This processing is done with respect to all sets of candidate factors. A low accuracy classification model having an accuracy score lower than a threshold criterion is selected. A higher accuracy classification model having an accuracy score that is higher than the accuracy score of the low accuracy classification model is selected. The set of candidate factors used to train the low accuracy classification model is updated using one or more of the candidate factors used to train the higher accuracy classification model. The low accuracy classification model is updated based on the updated set of candidate factors.

Abstract: This application relates to an inflatable colorectal outer wall constriction device designed for use in post-surgical anastomotic protection. The device consists of a support rod, a coiled inflatable tube, a head inflatable tube, a coiled inflatable balloon, and a head inflatable balloon. One end of the support rod includes an inflation port, while the other end is connected to both the coiled and head inflatable balloons. The tubes run through the hollow support rod, and when inflated, the coiled balloon curls into a ring while the head balloon expands, fitting securely into a slot near the coiled balloon. This configuration allows the device to apply pressure and form a tight seal between the outer intestinal wall and a fecal diversion device, preventing leakage. After the anastomosis has healed, the device can be deflated and easily removed, ensuring the proper protection of the surgical site during the healing process.
