IEEE SiPS 2018 Tutorial: Machine Learning Methods for Power/Performance/Thermal Optimization of Signal Processing Systems

IEEE SiPS 2018 Tutorial: Machine Learning Methods for Power/Performance/Thermal Optimization of Signal Processing Systems

This tutorial on ML for PPT will be held on Sunday, October 21 at IEEE SiPS 2018 in Cape Town, South Africa.

Tutorial Summary

This tutorial will cover machine learning methods for use at both design time and run time. We will cover two major machine learning methods: convolutional neural networks (CNNs) and Markov models. Each has very different uses in signal processing systems, particularly for PPT characteristics.

We will discuss efficient implementations of CNNs, including numerical representation, nonlinear function representations, and memory systems.  Topics include:

  • Introduction to convolutional neural networks: architecture, operation, classification, training.
  • Implementation technologies for CNNs: CPU software, GPU and tensor processor, FPGA, ASIC.
  • Required numerical precision for CNN arithmetic.
  • Memory system requirements for CNNs.

We will discuss the use of Markov chains and Markov decision processes for signal processing systems. We will discuss design-time use of Markov decision processes (MDPs) to build run-time controllers with optimized policies. We will discuss methods for online optimization of Markov decision processes for incremental policy optimization. Topics include:

  • Overview of Markov models and Markov decision processes.
  • Algorithms to solve MDPs: value iteration, policy iteration.
  • Hierarchical Markov decision processes.
  • Using MDPs during design space exploration.
  • Online training refinement for MDPs.
