Abstract: Some embodiments include a workflow authoring tool that accesses a text string representation of a workflow and a text string representation of at least a data processing operator type. The workflow authoring tool enables definition of one or more data processing operator types that can be referenced in defining the machine learning workflow. When scheduling a workflow, the text string representation of the workflow can be parsed and traversed to generate an interdependency graph of one or more data processing operators. The text string representation of the data processing operator type can identify operator attributes associated with the data processing operator type.

Abstract: Some embodiments include an experiment management interface for a machine learning system. The experiment management interface can manage one or more workflow runs related to building or testing machine learning models. The experiment management interface can receive an experiment initialization command to create a new experiment associated with a new workflow. A workflow can be represented by an interdependency graph of one or more data processing operators. The experiment management interface enables definition of the new workflow from scratch or by cloning and modifying an existing workflow. The workflow can define a summary format for its inputs and outputs. In some embodiments, the experiment management interface can automatically generate a comparative visualization at the conclusion of running the new workflow based on an input schema or an output schema of the new workflow.

Abstract: Some embodiments include a method of machine learner workflow processing. For example, a workflow execution engine can receive an interdependency graph of operator instances for a workflow run. The operator instances can be associated with one or more operator types. The workflow execution engine can assign one or more computing environments from a candidate pool to execute the operator instances based on the interdependency graph. The workflow execution engine can generate a schedule plan of one or more execution requests associated with the operator instances. The workflow execution engine can distribute code packages associated the operator instances to the assigned computing environments. The workflow execution engine can maintain a memoization repository to cache one or more outputs of the operator instances upon completion of the execution requests.

Abstract: A computer system for offering property for exchange over a computer network includes a master database for storage of information pertaining to the property that is located on at least one master server which can be accessed by an exchangee, e.g. through a browser. The system further includes local agent databases which store information pertaining to property offered for exchange by a particular exchanger. An agent server accesses the master server so as to transfer information stored on an agent database to the master database. The computer system also includes an exchange management program adapted to record information relating to the stages of exchange of property between the exchanger and the exchangees, wherein the exchangees access the master server and request particular information from the master database pertaining to the property.

Abstract: The invention is based on a continuously variable transmission comprising a mechanical power branch and an electronically controlled hydraulic power branch which can be adjusted via a swash plate (7), a summarizing transmission and a multi-stage transmission with hydraulically actuated, force-locking shift elements (11-14). The shift signals of the shift elements (11-14) are generally triggered when a shift or synchronizer speed is reached. Thereafter elapses a response or reaction time and an adjusting time until the shift elements (11-14) are engaged. This results in long clutch shift processes. It is proposed that the response and engagement times of the shift elements (11-14) be compensated by a control unit.

Abstract: An arrangement and process for operating a continuously variable drive unit of a motor vehicle having an apparatus for control of the operation of the clutches (25, 26) in the mechanical transmission branch (19). Sensors (7, 9, 45) transmit the speed of the mechanical transmission branch (19), the hydrostatic transmission branch (17) and the transmission output shaft (10) to an electronic control device (3). The clutches (25, 26) are disconnected in the case of inadmissible speed ratios.

Abstract: The invention concerns a continuously variable driving unit motor vehicles having a controllable internal combustion engine and a hydrostatic-mechanical power split transmission with continuously variable reduction ratio, wherein the transmission is set to the lowest possible resistance when the driving unit is started and when the vehicle is stationary with the internal combustion engine running or during a warm-up period, the motor vehicle does not move unintentionally.

Abstract: Arrangement and method for operating a continuously variable drive unit of a motor vehicle with a controllable internal combustion engine and a hydrostatic-mechanical power split transmission and a control device which, near the gear-shift points S1 or S2 at an approximately constant rotational speed of the output shaft of the power split transmission, reduces the speed n.sub.mot of the internal combustion engine starting from n.sub.1 and accelerates the resetting motion PHI or the swash plate up to the shift point, resets the motion PHI of the swash plate by a calculated load-dependent value K during gear shifting, and, in the new gear range at a further decreasing speed of the internal combustion engine and accelerated resetting of the swash plate exits the area close to the shift point with almost constant rotational speed of the output shaft of the transmission and then, at a constant PHI angle of the swash plate, the rotational speed of the output shaft is increased to the previous level n.sub.

Abstract: Arrangement and method of operating a variable drive unit with a selector switch for the preselection of a long-term speed and a control unit which allows for the continuous operation of a continuously variable power split transmission only at reduction ratios (.phi..sub.continuous) having a certain minimum interval (.phi..sub.min) from the reduction ratio at the shift points between the speed ranges in the mechanical branch of the transmission and the control unit changes the speed of the internal combustion engine in order to reach speeds lying within the minimum interval and controlled by changing the engine speed while maintaining reduction ratio of the transmission instant.
