Results:

  1. Extension of the Modeling Field Theory neural network for the classification of objects (as seen in ICANN 06)

the system can be applied to the classification of action patterns in the context of cognitive robotics view results

Description:

  • Test 1: Here we apply the multi-dimensional MFT algorithm to the data on the classification of the posture of robots, as in an imitation task.

This consist of the 7 main data (X, Y, Z, and rotations of joints 1, 2, 3, and 4) for each of the 6 segments of the robot’s arms (right shoulder, right upperarm, right elbow, left shoulder, left upperarm, left elbow). As training set we consider 5 postures: resting position with both arms open, left arm in front, right arm in front, both arms in front, and both arms down.

Figure 1: Evolution of fields in the robot posture classification task. The value of the field corresponds to equation (7). Although the five fields look very close, in reality the individual field values match very well the 42 parameters of the original positions.
