1. A method of controlling a vehicle comprising:
- determining an autonomous driving episode in response to a sensor signal;
segmenting the autonomous driving episode into a first event and a second event;
segmenting the first event into a first time step and a second time step and the second event into a third time step and a fourth time step;
generating a first association matrix in response to the first time step, a second association matrix in response to the second time step, a third association matrix in response to the third time step and a fourth association matrix in response to the fourth time step;
generating a transition matrix in response to the first association matrix, the second association matrix, the third association matrix and the fourth association matrix;
generating a 3D tensor in response to the transition matrix;
determining a probable time step in response to the 3D tensor;
generating a probable event in response to the probable time step; and
generating a control signal for controlling an autonomous vehicle in response to the probable event.

Abstract
The present application generally relates to a method and apparatus for generating an action policy for controlling an autonomous vehicle. In particular, the method is operative to receive an input indicative of a training event, segmenting the driving episode into a plurality of time steps, generate a parse tree in response to each time step, and generate a most probable parse tree from a combination of the generated parse trees.
