Abstract: Systems and methods for pre-processing data to facilitate efficient and accurate machine learning are provided. The data may include market data. The pre-processing may include partitioning the data into windows assigning categories to windows generate a series of vectors.

Abstract: A method and apparatus for publishing market data for a financial instrument utilizes existing network layer acknowledgement feature to publish market data for the financial instrument to a client device at rates in which the client device is able to process the data. The publishing rate is dynamic, as opposed to being fixed, and is able to adjust “on-the-fly” so as to prevent message queue stagnation.

Abstract: A telephone system supports communication with user devices over both a cellular radio network as well as over an Internet Protocol (IP) network, and enables roaming and active call handoff between cellular and IP domains. Components of the system interact with conventional cellular telephone systems, for example, by emulating behavior of control components, providing proxy services for conventional components, transporting cellular telephone control communications over IP connections, or by simulating cellular operating characteristics of user devices operating in an IP domain.
