Abstract: A system and method for training and using a machine-learning similarity framework are provided. During training, the similarity framework generates an ensemble of tress. The trees have different properties at each node. The similarity framework uses the ensemble of trees to determine similarity between objects. The objects are propagated through nodes of each tree in the ensemble of trees until the objects reach leaf nodes. The objects are propagated by comparing the properties at each node of the tree to the features of the objects until the objects reach the leaf nodes. The similarity framework determines a similarity score for a pair of objects in each tree and adjusts the similarity score by tree importance. The object similarity score is determined by combining the similarity scores from multiple trees in the ensemble of trees. The similarity framework generates a similarity matrix that stores object similarity scores for multiple pairs of objects.

The objects are propagated through nodes of each tree in the ensemble of trees until the objects reach leaf nodes. The objects are propagated by comparing the properties at each node of the tree to the features of the objects until the objects reach the leaf nodes. The similarity framework determines a similarity score for every two objects in each tree and adjusts the similarity score by tree importance. The object similarity score is determined by combining the similarity scores from the trees in the ensemble of trees. The similarity framework generates a similarity matrix with the object similarity scores of the every two objects.

Abstract: A massaging device includes a housing including a recessed top and a channel in the recessed top; a motor having an eccentric shaft securely mounted in the channel; a vibration member mounted on the motor; a massaging pad mounted on the vibration member; and a plurality of rubber cylinders mounted around an edge of the recessed top and secured to a bottom of the vibration member. The housing further includes means for absorbing the force of shocks and jarring generated by the activating motor. A peripheral gap is formed between the motor and an inner surface of the channel. The motor further includes a bottom fan adapted to introduce cool air from an underside of the housing into the housing for dissipating heat generated by the activating motor through the gap.
