20110082823 | Thought Dynamo Decision Mapping Model - The Thought Dynamo Decision (TDD) Mapping Model includes three overlapping 3-D grids that represent decisions from the perspectives of intellect, emotions and imagined outcomes. The continuums of the logic of intellect are power-powerless, good-evil and accuracy-intuitive. The logic of emotion has three continuums: trust-fear, honor-shame, freedom-bonding. And the imagined outcomes continuums are thriving-surviving, desired identity-undesired identity, and meaningful-meaningless. The intersection of each grid forms a central tendency: creative harmony of jealous space. A five step process is used for mapping thoughts and decisions: plot, associate, adjust, solidify and employ. The dynamics of thought and decision are mapped by assigning weights to inputs, strength to associations, dynamically accounting for adjustments and solidifications over time and projecting rules of thumb in decision making onto (3) 3-D axes. This model accounts for decision differences across cultures as illustrated by an examination of the Japanese construct of “amae”. | 04-07-2011 |

20120330870 | METHOD AND APPARATUS FOR A LOCAL COMPETITIVE LEARNING RULE THAT LEADS TO SPARSE CONNECTIVITY - Certain aspects of the present disclosure support a local competitive learning rule applied in a computational network that leads to sparse connectivity among processing units of the network. The present disclosure provides a modification to the Oja learning rule, modifying the constraint on the sum of squared weights in the Oja rule. This constraining can be intrinsic and local as opposed to the commonly used multiplicative and subtractive normalizations, which are explicit and require the knowledge of all input weights of a processing unit to update each one of them individually. The presented rule provides convergence to a weight vector that is sparser (i.e., has more zero elements) than the weight vector learned by the original Oja rule. Such sparse connectivity can lead to a higher selectivity of processing units to specific features, and it may require less memory to store the network configuration and less energy to operate it. | 12-27-2012 |
