The operating section holds a required accuracy, and an internal state and a weight value of a learner in the memory and executes calculation processing by using data input to the machine learning system and the weight value held in the memory to update the internal state. An accuracy of the internal state is calculated from a result of the calculation processing and an evaluation value is calculated using the data input to the machine learning system, the weight value, and the updated internal state held in the memory when the calculated accuracy is higher than the required accuracy. The evaluation value is transmitted to the learning section, which updates the weight value by using the evaluation value and notifies the number of times of updating the weight value to the operating section.

Abstract

The objective of the present invention is to provide a sensing performance evaluation and diagnosis system with which a malfunction predictor of an external environment recognition sensor being diagnosed can be detected by comparing the output of the external environment recognition sensor being diagnosed and the output of an external environment recognition sensor serving as a reference, without relying on reference information registered in advance in a map. The sensing performance evaluation and diagnosis system is characterized by being equipped with: a sensing data acquisition unit for acquiring sensing data for the periphery of a host vehicle from observation values of an external environment sensor that is mounted on the host vehicle and is to be diagnosed; a periphery information acquisition unit for acquiring periphery information data about the periphery of the host vehicle from observation values of a reference external environment sensor; a reference value calculation unit for generating reference value data on the basis of a recognition history of relative information with respect to a reference object included in the periphery information data; and an evaluation unit for comparing the sensing data pertaining to the reference object to a threshold value that has been set for the reference value data, and thereby evaluating whether the performance of the external environment sensor being diagnosed has deteriorated or evaluating a degree of deterioration in the performance.

Abstract

According to the present invention, a positional information antenna 22b receives a position signal including positional information of a transmission source (satellite, base station, etc.) of position measurement electromagnetic wave. A communication antenna 22a transmits the positional information of a compressor 100 (air compressor) for compressing air, and receives meteorological information corresponding to the position of the compressor 100 from a server on cloud. A control device 13 specifies the position of the compressor 100 from the position signal received by the positional information antenna 22b, and controls the compressor 100 on the basis of the meteorological information that is received by the communication antenna 22a and corresponds to the position of the compressor 100.

Abstract

Example implementations described herein are directed to systems and methods for selecting appropriate data samples and features in an access and privacy restricted system. Example implementations involve selection of appropriate samples (e.g. patients) which have enough data sources bringing highly important factors based on the experienced risk factors at other facilities, which is stored as metadata. The risk factor management puts more prioritization on some patients which have more data in the required data source than the other patients among all data sample candidates. The similarity of the training data sample can be a criteria to select new sample sets. Further, the risk factor management selects valuable features effectively based on metadata derived from other facilities. Example implementations help improve machine learning accuracy as part of daily system management in a facility, and can be deployed across facilities without compromising access or privacy restrictions of the data.

There is a problem that it takes a long time to park a vehicle because the vehicle has to be returned to a position outside the parking frame and parked. In step S160, the correction judgment unit 142 judges from the necessary correction amounts calculated in steps S140 and S150 and the remaining distance to the re-targeted parking position that is re-recognized, whether or not correction of the parking route with this remaining distance is possible. In a case where it is judged in step S160 that correction with the remaining distance r2 is impossible, the vehicle is stopped in step S171. Even if it is judged in step S160 that the correction is impossible, when the vehicle is moved backward toward the parking frame is parked, the vehicle is obliquely parked in the parking frame and cannot be fit neatly in the parking frame. In step S172, a parking route including a turnabout is regenerated with respect to the re-targeted parking position calculated in step S130 while the stopped state is maintained.
