  • Patent number: 4912655
    Abstract: A method of accelerating the training of an artificial neural network uses a computer configured as an artificial neural network with a network input and a network output, and having a plurality of interconnected units arranged in layers including an input layer and an output layer. Each unit has a multiplicity of unit inputs and a set of variables for operating upon a unit inputs to provide a unit output. The computer is programmed with a back propagation algorithm. A plurality of examples are serially provided to the network input and the network output is observed. The examples are iterated and proposed changes to each set of variables are calculated in response to feedback representing differences betwen the network output for each example and the desired output. The proposed changes are accumulated for a predetermined number of iterations, whereupon the accumulated proposed changes are added to the set of variables.

Each unit has a multiplicity of unit inputs and a set of variables for operating upon the unit inputs to provide a unit output. A plurality of examples are serially provided to the network input and the network output is observed. The computer is programmed with a back propagation algorithm for adjusting each set of variables in response to feedback representing differences between the network output for each example and the desired output. The examples are iterated while those values which change are identified. The examples are reiterated and the algorithm is applied to only those values which changed in a previous iteration.

    Abstract: A method of accelerating the training of an artificial neural network uses a computer configured as an artificial neural network with a network input and a network output, and having a plurality of interconnected units arranged in layers including an input layer and an output layer. Each unit has a multiplicity of unit inputs and a set of variables for operating upon a unit inputs to provide a unit output. A plurality of examples are serially provided to the network input and the network output is observed. The computer is programmed with a back propagation algorithm for adjusting each set of variables in response to feedback representing differences between the network output for each example and the desired output. The examples are iterated until the signs of the outputs of the units of the output layer converge. Then each set of variables is multiplied by a multiplier. The examples are reiterated until the magnitude of the outputs of the units of the output layer converge.

  • Patent number: 4912653
    Abstract: A trainable artificial neural network includes a computer configured as a plurality of interconnected neural units arranged in a layered network. An input layer has a network input and an output layer has a network output. A neural unit has a first subunit and a second subunit, with the first subunit having one or more first inputs and a corresponding first set of variables for operating upon the said first inputs to provide a first output. The first set of variables can change in response to feedback representing differences between desired network outputs and actual network outputs. The second subunit has a plurality second inputs, and a corresponding second set of variables for operating upon said second inputs to provide a second output. The second set of variables can change in response to differences between desired network outputs for selected network inputs and actual network outputs.

  • Patent number: 4912647
    Abstract: A method of training an artificial neural network uses a first computer configured as a plurality of interconnected neural units arranged in a network. A neural unit has a first subunit and a second subunit. The first subunit has first inputs and a corresponding first set of variables for operating upon the first inputs to provide a first output during a forward pass. The first set of variables can change in response to feedback representing differences between desired network outputs and actual network outputs. The second subunit has a plurality of second inputs, and a corresponding second set of variables for operating upon the second inputs to provide a second output. The second set of variables can change in response to differences between desired network outputs for selected network inputs and actual network outputs. The computer provides an activating variable representing the difference between current second output and previous second outputs.

  • Patent number: 6156004
    Abstract: An apparatus for irrigating a local irrigation site includes a suction/irrigation tip that is removably connected to a suction/irrigation handpiece. The tip has an irrigation tube for directing irrigation liquid to the irrigation site, and a suction tube coaxially aligned within the irrigation tube. The handpiece pumps irrigation liquid from an external reservoir, through the annular space between the irrigation tubes and the suction tube to the irrigation site. Suction is applied to the site through the central suction lumen which has a large unobstructed opening to reduce clogging. A flexible splash shield, slidably mounted to the tip, is conically shaped and extends distally from a collar to a rim. The rim is sized to fit around and about the local site.

  • Patent number: 7886989
    Abstract: An apparatus for dispensing liquid material includes a dispensing module having a liquid supply passage communicating with a supply of liquid material and an air supply passage communicating with a source of pressurized air. A nozzle is coupled to the dispensing module and has a liquid discharge passage and an air discharge passage communicating with the liquid supply passage and the air supply passage, respectively. The liquid material is dispensed from a liquid discharge outlet of the nozzle and pressurized air is directed from an air outlet of the nozzle toward the dispensed liquid material. An air valve coupled to the nozzle is operable to vary the pressure of the air discharged from the air outlet to thereby move the liquid material in a desired pattern. In an exemplary embodiment, the valve is operable to pulse the pressurized air.
