An interactive learning cycle includes an operator, a computer and a pool of images. The operator produces a sparsely-labeled data set. A back-end system produces live feedback: a densely-labeled training set which is displayed on the computer. Immediate feedback is displayed in color on the operator computer in less than about five seconds. A labeling tool displays a user interface and for every labeling project a region is defined that is downloaded as an image data batch. The operator annotates on a per-image basis in the region and uses several UI tools to mark features in the image and group them to a predefined label class. The back-end system includes processes that run in parallel and feed back into each other, each executing a model. A local model is used independently of the global model. The global model accepts sparsely-labeled images from numerous operator computers.

A method is proposed for manufacturing a pipe-lining material comprising a tubular resin absorbent material covered with a tube comprised of an airtight plastic film. The tubular resin absorbent material is inserted into the tube, expanded in a columnar shape, and brought into close contact with the internal peripheral surface of the tube. A heater is wound in close contact with the external peripheral surface of the tube thus expanded. The tube and the tubular resin absorbent material are heated by energizing the heater, and the tube is thereby heat-fused to the tubular resin absorbent material.
