A method for automated machine learning includes controlling execution of a plurality of instantiations of different automated machine learning frameworks on a machine learning task each as a separate arm in consideration of available computational resources and time budget. During the execution by the separate arms, a plurality of machine learning models are trained and performance scores of the plurality of trained machine learning models are computed such that one or more of the plurality of trained machine learning models are selectable for the machine learning task based on the performance scores. This invention can be used for predicting patient discharge, predictive control in buildings for energy optimization, and so on.

A method for automatically selecting a machine learning algorithm and tuning hyperparameters of the machine learning algorithm includes receiving a dataset and a machine learning task from a user. Execution of a plurality of instantiations of different automated machine learning frameworks on the machine learning task are controlled each as a separate arm in consideration of available computational resources and time budget, whereby, during the execution by the separate arms, a plurality of machine learning models are trained and performance scores of the plurality of trained models are computed. One or more of the plurality of trained models are selected for the machine learning task based on the performance scores.

A method for providing a demand-response (DR) signal assignment includes initializing reinforcement learning (RL) agents, each having an exploration scheme and being assigned to a consumer, with initial models about respective RL environments of the consumers. The RL agents send the models to an optimizer. The optimizer computes a DR signal assignment using the models. The RL agents send DR signals in accordance with the DR signal assignment to the consumers so as to aggregately achieve a load reduction by the consumers over a time window. The RL agents monitor the consumers over the time window, and update the models based on the monitoring.

A method for accessing service/data of a first network from a second network includes accessing the services and data of the first network from the second network includes registering a user device with the first network to access the services or data of the first network. The user device connects with the second network and authenticates the user device with the second network subsequent to registering the user device with the first network. The user device provides connectivity information of the first network to the second network to configure the second network to access the services or data of the first network. The first network is able to provide the services or data to the second network based on the user device being registered to access the services or data prior to being authenticated with the second network.
