Abstract: Machine learning (ML) processes ranks data instances to determine when to adjust parameters of a machine learning model. Data instances are ranked by receiving data instances. Further, ranked instances are determined based on the data instances and a machine learning model. A metric is determined based on the ranked instances. An adjusted machine learning model is generated by adjusting one or more parameters of the machine learning model based on the metric.

Abstract: A low vibration and noise reduction exercise mat unit has a buffer plate and multiple protruding portions. The buffer plate has a board, multiple male buckles, and multiple female buckles. The board is quadrilateral and has a bottom, a recess, and a flange. The recess is formed on a bottom surface of the board. The flange is formed around the recess. The multiple protruding portions are disposed at spaced intervals in the recess of the board. The multiple protruding portions protrude downwardly from an inner top surface of the recess of the board. The buffer plate and the multiple protruding portions are made of natural rubber, will not affect the human body, and are stable in quality. The male buckles and female buckles can enhance the connecting strength between the mat units.

Abstract: A technique plate in accordance with the present invention has a dimension ring, two clamping disks and a sleeve. The dimension ring has an internal edge, two side surfaces and a clamping protrusion. The clamping protrusion is formed on and protrudes from the internal surface. The clamping disks are mounted on and clamp the clamping protrusion of the dimension ring. Therefore, compared to a conventional technique plate of the same diameter, the technique plate of the present invention is lighter, so the distance between a bar of a barbell and the ground is higher to prevent beginner's injury.

Abstract: A read only memory circuit for debugging and updating, the circuit includes read only memory, debug program memory, program counter, and compare and load unit. In the circuit, the compare and load unit detects instruction-read-memory-address from the program counter. If the instruction-read-memory-address is a predetermined main program address, the compare and load unit serves to transmit a debug address in the debug program memory to the program counter to update the original instruction-read-memory-address for debugging.

Abstract: A method of making a rubber barbell weight with as least on colored rubber belt has acts of providing at least one annular colored rubber belt, providing a mold, placing the at least one annular colored rubber belt in the mold, placing rubber raw materials in the mold, heating and pressing the mold and releasing the mold. The mold has two middle molds. Each middle mold has at least one recess formed radially in an inside wall of the mold. The annular colored rubber belt is placed into the recesses of the middle molds. The rubber raw materials are placed into the mold. Because top and bottom flanges of each recess of the middle mold limit the annular colored rubber belt only fusing with adjacent rubber raw materials, an outside surface of the annular colored rubber belt does not mix with the color of the rubber raw materials.
