1. A method of planning escape from a threat in a venue comprising:

  • operating a machine learning system implemented on a first processor with a machine learning model subsequent to the detection of the threat to produce a plan of escape from the venue, wherein;

    (a) the model has been pre-trained in a first step on a second processor with data concerning at least one of layout of venues, methods of escape from venues, and behavior of persons attempting to escape from a venue in a hazardous condition;

    (b) the model has been transferred to one of the first processor and a third processor subsequent to the first step and prior to entry into the venue by a person;

    (c) the model has been trained in a second step subsequent to the transfer and subsequent to entry into the venue by the person on one of the first processor and the third processor with data gathered subsequent to the entry with a sensor concerning at least one of a location of the person in the venue and behavior of persons attempting to escape from the venue; and

    (d) the model subsequent to the second step is used to produce the plan of escape;

    (e) the first processor has a memory containing a program to use the machine learning model to produce an instruction to escape from the venue subsequent to the detection of a hazard in the venue; and
