Event correlation |
| 摘要 |
A method for event correlation includes capturing events and arranging the events sequentially in at least one dimension. An event correlator implemented by a computational device convolves a kernel density function with each of the events to produce a convolved function for each event. Co-occurrences between events are found by calculating overlap between convolved functions. |

1. A method for event correlation comprising:
capturing events including a first event and a second event and arranging the events sequentially in at least one dimension; convolving, with an event correlator implemented by a computational processor, a kernel density function with each of the events to produce a convolved function for each event, wherein the convolving includes:
producing a first convolved function associated with the first event; andproducing a second convolved function associated with the second event; and finding co-occurrences between events, wherein the finding of co-occurrences includes:
calculating an area of overlap between the first convolved function and the second convolved function; andfinding a co-occurrence between the first event and the second event based on the area of overlap. |
