The DEEM workshop will be held on Sunday, 14th of June in Portland, OR in conjunction with SIGMOD/PODS 2020. DEEM brings together researchers and practitioners at the intersection of applied machine learning, data management and systems research, with the goal to discuss the arising data management issues in ML application scenarios.

The workshop solicits regular research papers describing preliminary and ongoing research results. In addition, the workshop encourages the submission of industrial experience reports of end-to-end ML deployments. Submissions can be short papers (4 pages) or long papers (up to 10 pages) following the ACM proceedings format. Please use the latest ACM paper format (2017) and change the font size to 10 pts (analogous to SIGMOD).

Integrative Data Equity Systems [Academic Keynote] [Video]
Bill Howe (University of Washington)

Abstract: As the deployment of automated decision tools in society continues to accelerate, their interactions with fundamental questions in law, in the social sciences, and in public policy have become impossible to ignore. Although this technology holds the promise of reducing costs, reducing errors, and improving objectivity, there is enormous potential for harm. As we train algorithms on biased data, we are amplifying, operationalizing, and, most insidiously, legitimizing the historical discrimination and opacity that the technology was in part intended to address. End-to-end data systems provide abstractions to hide complexity behind (hopefully) simpler contractual interfaces. But as these systems are deployed in complex and changing social contexts, their abstractions can reduce transparency and exacerbate equity issues: It gets easier to do the wrong thing. In this talk, I’ll argue that data systems research needs to broaden scope to explicitly model, manage, and communicate assumptions and requirements about the contexts in which they are deployed, making equity issues a first-class design consideration. I'll provide some examples of the tensions, and describe some projects in this space, including learning fair representations of heterogeneous data to combat bias and providing interactive warning labels to communicate fitness for use downstream. I’ll end with some thoughts about how academic research in this space can be conducted more responsibly.

Apache SystemDS: An ML System for the End-to-End Data Science Lifecycle [Video]
Matthias Boehm (Graz University of Technology)

Abstract: Machine learning (ML) applications become increasingly common in many domains. Existing ML systems to execute these workloads include numerical computing frameworks, ML algorithm libraries, and more specialized deep neural network frameworks. These systems focus primarily on efficient model training and scoring. However, the data science process is exploratory, and deals with underspecified objectives, a range of different algorithms, and a wide variety of heterogeneous data sources with various errors and inconsistencies. Therefore, additional tools are employed for data engineering, exploration, and debugging, which requires boundary crossing, unnecessary manual effort, and lacks optimization across the lifecycle. This talk introduces Apache SystemDS, an open source ML system for the end-to-end data science lifecycle from data integration, cleaning, and preparation, over local and distributed model training, to debugging and serving. In a first part, we describe the overall system architecture and major design decisions that are motivated by lessons learned from Apache SystemML. In a second part, we then share early ideas and preliminary results of selected features including (1) lineage-based reuse of intermediates, (2) federated ML over raw data, and (3) the automatic tuning of data cleaning pipelines.

Can you do impactful MLSys work outside of large companies? [Video]
Manasi Vartak (Verta AI)

Abstract: A lot of the most impactful MLSys work in recent years (e.g., Tensorflow, PyTorch, Michelangelo) has come from industry and particularly large companies. This is rather unusual compared to the field of databases where lots of high-impact work was done in academia too and this can leave academics wondering how to make a dent in this extremely interesting but also extremely competitive research area. In this talk, I will present some perspectives (supported by several examples) on why so much of the MLSys innovation has come from large companies so far and present a simple, anecdotal framework to assess whether a given MLSys problem is amenable to research in a large company, a startup, or academic setting. I will conclude by presenting several research problems, which based on this framework, are particularly well suited for academia and hope that the broader research community adopts them!

XLA : Compiling Machine Learning for Peak Performance [Industry Keynote] [Video]
Amit Sabne (Google Brain)

Abstract: XLA (accelerated linear algebra) is a compiler-based linear algebra execution engine. It is the backend that powers machine learning frameworks such as TensorFlow and JAX at Google, on a variety of devices including CPUs, GPUs, and TPUs. This talk will cover how ML growth has fueled accelerator architectures and the way XLA and related technologies help obtain high performance from the accelerators. Unlike traditional compilation methods, where high-level programs are first translated into a common intermediate representation (IR) and only during final code-generation architecture-specific optimizations are applied, XLA compiler maps the IR to accelerator architecture constructs much earlier. This talk will demonstrate how such early architecture mapping is essential for peak performance, how it performs on real-world workloads, and the related techniques under the hood.

Call for Papers

Applying Machine Learning (ML) in real-world scenarios is a challenging task. In recent years, the main focus of the database community has been on creating systems and abstractions for the efficient training of ML models on large datasets. However, model training is only one of many steps in an end-to-end ML application, and a number of orthogonal data management problems arise from the large-scale use of ML, which require the​ attention​ of​ the​ data​ management​ community.

For example, data preprocessing and feature extraction workloads result in complex pipelines that often require the simultaneous execution of relational and linear algebraic operations. Next, the class of the ML model to use needs to be chosen, for that often a set of popular approaches such as linear models, decision trees and deep neural networks have to be tried out on the problem at hand. The prediction quality of such ML models heavily depends on the choice of features and hyperparameters, which are typically selected in a costly offline evaluation process, that poses huge opportunities for parallelization and optimization. Afterwards, the resulting models must be deployed and integrated into existing business workflows in a way that enables fast and efficient predictions, while still allowing for the lifecycle of models (that become stale over time) to be managed. Managing this lifecycle requires careful bookkeeping of metadata and lineage (“which data was used to train this model?”, “which models are affected by changes in this feature?”) and involves methods for continuous analysis, validation, and monitoring of data and models in production. As a further complication, the resulting systems need to take the target audience of ML applications into account; this audience is very heterogeneous, ranging from analysts without programming skills that possibly prefer an easy-to-use cloud-based solution on the one hand, to teams of data processing experts and statisticians developing and deploying custom-tailored algorithms​ on​ the​ other​ hand.
Additionally, the importance of incorporating ethics and legal compliance into machine-assisted decision-making is being broadly recognized. Critical opportunities for improving data quality and representativeness, controlling for bias, and allowing humans to oversee and impact computational processes are missed if we do not consider the lifecycle stages upstream from model training and deployment. DEEM welcomes research on providing system-level support to data scientists who wish to develop and deploy responsible machine learning methods.

DEEM aims to bring together researchers and practitioners at the intersection of applied machine learning, data management and systems research, with the goal to discuss the arising data management issues in ML application scenarios. The workshop solicits regular research papers describing preliminary and ongoing research results. In addition, the workshop encourages the submission of industrial experience reports of end-to-end ML deployments.
