Learning Structure for Computer Systems Management

Abstract

Modern computer systems expose diverse configurable parameters whose complicated interactions have surprising effects on performance and energy. This puts a great burden on systems designers and researchers to manage such complexity. Machine learning (ML) creates an opportunity to alleviate this burden by modeling resources' complicated, non-linear interactions and deliver an optimal solution to scheduling and resource management problems. However, naively applying traditional ML methods, such as deep learning, creates several challenges including generalization, robustness, and interpretability. A lack of generalizability and robustness in the ML models is largely due to the scarcity and bias of the training data. Causal inference creates an opportunity to tackle these challenges by analyzing observational data rather than data generated from randomized experiments. Since causal inference inherently studies the causal relationships---underlying structure---rather than correlation between features, it also provides interpretable systems results. This poster describes my PhD research on applying ML to systems along with key techniques from causal inference, characterizing my specific goals of: (1) learning for systems optimization with scarce data and system structure, and (2) learning for straggler prediction with imbalanced data.
