We present a new approach to the supervised learning of lateral inter- actions for the competitive layer model (CLM) dynamic feature binding architecture. The method is based on consistency conditions, which were recently shown to characterize the attractor states of this linear threshold recurrent network. For a given set of training examples the learning prob- lem is formulated as a convex quadratic optimization problem in the lat- eral interaction weights. An efficient dimension reduction of the learning problem can be achieved by using a linear superposition of basis inter- actions. We show the successful application of the method to a medical image segmentation problem of fluorescence microscope cell images.
