Abstract: Systems and methods disclose herein procedures for accelerated tree learning. In one class, the acceleration is based on self-adapting learning rates, while in another class, the acceleration is based on a plurality of learning rates, wherein each learning rate varies over the training; each learning rate increases linearly as a respective pseudo residual maintains a direction across sequential training iterations; and each learning rate decreases exponentially as the respective pseudo residual changes direction across sequential training iterations. The latter can be incorporated with other methodologies, such as momentum-augmented gradient boosting and Nesterov Accelerated Gradient Boosting. These systems and methods for accelerated tree learning exhibit a marked reduction in training time and resources required for gradient boosted trees.

The fire pump unit can be operated in accordance with a control curve based on detected pressure and flow. The control curve can include: a) a first setpoint of rated total value of the system load for the pressure and the flow, b) a second setpoint of a minimum partial percentage of the rated total value of the pressure at an over-percentage of the rated total value of the flow, c) a path which maintains the rated total value of the pressure for all values of the flow up to the first setpoint, d) a path between the first setpoint and the second setpoint, e) a path from the second setpoint which limits values of the pressure for values of the flow greater than the second setpoint.

Abstract: Performance mapping of equipment performance parameters by capturing, mapping, and/or structuralizing equipment performance data of a device for installation in a system. This includes generating performance maps which outline the expected feature performance parameter behavior of the equipment based on a set of operating parameters that capture the operating conditions. Each performance parameter on the map is representative of an operating point of specific operating conditions taken at a particular point in time. In one example, a performance parameter can be defined by an individualized set of parameter coefficients which in turn are dependent on instantaneous operating conditions.
