  • Air-pollution anomaly location mechanism
    Patent number: 10338047
    Abstract: A mechanism is provided for detecting air-pollution anomalies. A historical air-pollution pattern is identified for each of a plurality of air-pollution monitoring stations. For each of the plurality of air-pollution monitoring stations, responsive to receiving real-time data from a particular air-pollution monitoring station, the real-time data is compared to the historical air-pollution pattern associated with the particular air-pollution monitoring station. A density difference value is generated based on the comparison of the real-time data to the historical air-pollution pattern associated with the particular air-pollution monitoring station and a determination is made as to whether the density difference value is greater than a predetermined confidence threshold.
