other words, the above equation scales the gradients from Gradient Descent with a reward signal . The reward signal is based on the accuracy of the child network over the dataset of interest. The policy networks. NASNet searches for the cells that are fitted into a hand-designed child network. The reward signal to the controller is still based on the performance of the child network which tunes it to search for a target child. The early RL based NAS models used the validation accuracy as a primary reward signal which is perfect for the applications that have sufficient compute resources at their disposal. However

a black-box • SISO models - MIMO too complex • Action • predictive, dataflow-wide The output signal is the delay time ??? Vasiliki Kalavri | Boston University 2020 Control theory models 10 • a black-box • SISO models - MIMO too complex • Action • predictive, dataflow-wide The output signal is the delay time Performance depends on parameter selection, e.g. poles placement, sampling externally observed coarse-grained and aggregates • CPU utilization, throughput, back- pressure signal • Policy • rule-based • If CPU utilization > 70% and back- pressure then scale up • Action
