Abstract: Methods and processors for using a Neural Network (NN) are disclosed. The method includes, during a first iteration, determining a first sub-network of the NN and training the first sub-network. The method includes during a second iteration a second sub-network of the NN and training the second sub-network. The method includes during an inference iteration of the NN, selecting a target sub-network amongst the first sub-network and the second sub-network, and generating an inference output by employing only the target sub-network of the NN on inference data for reducing computational resources of the processor for generating the inference output.

Abstract: Herein are acceleration and increased reliability based on classification and scoring techniques for machine learning that compare two similar datasets of different ages to detect data drift without a predefined drift threshold. Various subsets are randomly sampled from the datasets. The subsets are combined in various ways to generate subsets of various age mixtures. In an embodiment, ages are permuted and drift is detected based on whether or not fitness scores indicate that an age binary classifier is confused. In an embodiment, an anomaly detector measures outlier scores of two subsets of different age mixtures. Drift is detected when the outlier scores diverge. In a two-arm bandit embodiment, iterations randomly alternate between both datasets based on respective probabilities that are adjusted by a bandit reward based on outlier scores from an anomaly detector. Drift is detected based on the probability of the younger dataset.
