Prediction of an event affecting a physical system

A non-transitory computer readable medium having stored thereon a computer program comprising instructions for performing a method for predicting new occurrences of an event of a physical system, the method comprising:

• obtaining a first set of past events of the physical system, each past event comprising several attributes;
• obtaining a signature for each past event of the first set;
• obtaining a new event comprising several attributes;
• computing a signature of the new event;
• computing a similarity measure between the signature of the new event and each signature of each past event of the first set;
• determining the past events closest to the new event according to the similarity measures thereby forming a second set of past events;
• computing a score of relevance for each attribute of the second set;
• and
• generating a set of attributes by selecting the attributes having the greater scores of relevance.

A system comprising:

• a processor coupled to a memory, the memory having recorded thereon a computer program for predicting new occurrences of an event of a physical system that when executed by the processor causes the processor to be configured to:
• obtain a first set of past events of the physical system, each past event comprising several attributes;
• obtain a signature for each past event of the first set;
• obtain a new event comprising several attributes;
• compute a signature of the new event;
• compute a similarity measure between the signature of the new event and each signature of each past event of the first set;
• determine the past events closest to the new event according to the similarity measures thereby forming a second set of past events;
• compute a score of relevance for each attribute of the second set;
• and
• generate a set of attributes by selecting the attributes having the greater scores of relevance.
