Abstract: A neural network can be used to determine edit operations for normalizing an electronic communication. For example, an electronic representation of multiple characters that form a noncanonical communication can be received. It can be determined that the noncanonical communication is mapped to at least two canonical terms in a database. A recurrent neural network can be used to determine one or more edit operations usable to convert the noncanonical communication into a normalized version of the noncanonical communication. In some examples, the one or more edit operations can include inserting a character into the noncanonical communication, deleting the character from the noncanonical communication, or replacing the character with another character in the noncanonical communication. The noncanonical communication can be transformed into the normalized version of the noncanonical communication by performing the one or more edit operations.

Abstract: Electronic communications can be normalized using neural networks. For example, an electronic representation of a noncanonical communication can be received. A normalized version of the noncanonical communication can be determined using a normalizer including a neural network. The neural network can receive a single vector at an input layer of the neural network and transform an output of a hidden layer of the neural network into multiple values that sum to a total value of one. Each value of the multiple values can be a number between zero and one and represent a probability of a particular character being in a particular position in the normalized version of the noncanonical communication. The neural network can determine the normalized version of the noncanonical communication based on the multiple values. Whether the normalized version should be output can be determined based on a result from a flagger including another neural network.

Abstract: The invention features a computerized racing system designed to allow its users to engage in the sport of car racing, such as racing in full measure. System 100 features a race track connected to a computer games console that incorporates software that allows users to engage in video style racing on the race track. Virtual cars are built virtually allowing the user to customize the car and its performance features having assigned performance codes. The performance codes are sent from the race track to an actual race car when the actual race car contacts the track. The actual race car performs based on the customized performance features selected by the user.

Abstract: A bore cleaning device is disclosed that is configured to clean a bore of a firearm. Devices disclosed herein receive force manually applied by the user to push, pull, or propel the device through the bore. The device includes an internal mechanism configured to translate one of a pushing force and a pulling force into an outward radial force forcing intimate contact between device surfaces and interior walls of the bore.

Abstract: A system for filtering breathing air and apparatus for accomplishing the same. The invention describes a nasal filtration system which can be inserted into the nasal cavities.
