The inconsistency and redundant attributes of a sample data set will drop the classification quality and efficiency. In this paper, the method that can make the classification data set consistent and select a smallest feature variable set is proposed. This method groups together the inconsistent datum of the most likely category to make the data set(More)
Using a FeCoSiB amorphous wire and a coil wrapped around it, we have developed a sensitive magnetic sensor. When a 5 mm long amorphous wire with the diameter of 0.1 mm was used, the magnetic field noise spectrum of the sensor was about 30 pT/ÖHz above 30 Hz. To show the sensitivity and the spatial resolution, the magnetic field of a thousand Japanese yen(More)
An approach for mobile robot path planning based on particle filter is proposed. Ferguson splines have been used as a path description to ensure the smoothness of the path. Supposing the best path as the true state, and the others as states polluted by noise,the problem of searching for the best path has been transferred to a filter problem. Therefore the(More)
