• Authors: Robert Underwood, Jon C. Calhoun, Sheng Di, Franck Cappello,
• Abstract summary: Learning and Artificial Intelligence (ML/AI) techniques have become increasingly prevalent in high performance computing. Data compression can be a solution to these problems, but an in-depth understanding of how lossy compression affects model quality is needed. We show modern lossy compression methods can achieve a 50-100x compression ratio improvement for a 1% or less loss in quality.

• Abstract: Learning and Artificial Intelligence (ML/AI) techniques have become increasingly prevalent in high performance computing (HPC). However, these methods depend on vast volumes of floating point data for training and validation which need methods to share the data on a wide area network (WAN) or to transfer it from edge devices to data centers. Data compression can be a solution to these problems, but an in-depth understanding of how lossy compression affects model quality is needed. Prior work largely considers a single application or compression method. We designed a systematic methodology for evaluating data reduction techniques for ML/AI, and we use it to perform a very comprehensive evaluation with 17 data reduction methods on 7 ML/AI applications to show modern lossy compression methods can achieve a 50-100x compression ratio improvement for a 1% or less loss in quality. We identify critical insights that guide the future use and design of lossy compressors for ML/AI.

  DLRM is a state-of-the-art recommendation system model that has gained widespread adoption across various industry applications. A significant bottleneck in this process is the time-consuming all-to-all communication required to collect embedding data from all devices. We introduce a method that employs error-bounded lossy compression to reduce the communication data size and accelerate DLRM training.

  This paper focuses on non-linear two-layer autoencoders trained in the challenging proportional regime. Our results characterize the minimizers of the population risk, and show that such minimizers are achieved by gradient methods. For the special case of a sign activation function, our analysis establishes the fundamental limits for the lossy compression of Gaussian sources via (shallow) autoencoders.

  We propose DeepSketch, a new reference search technique for post-deduplication delta compression. DeepSketch uses a deep neural network to extract a data block's sketch, i.e., to create an approximate data signature of the block. Our evaluation shows that DeepSketch improves the data-reduction ratio by up to 33% (21% on average) over a state-of-the-art post-deduplication delta-compression technique.
