Call for Participation
WAX is a workshop on approximate computing, a research direction that asks how computer systems can be made better—faster, more efficient, and less complex—by relaxing the requirement that they be exactly correct. Approximation arises from sources as diverse as sensors, machine learning algorithms, and big data applications. Approximate systems raise questions from across the system stack, from circuits to applications. WAX is a venue for discussion, debate, and brainstorming on all of these topics.
With transistor scaling becoming less effective at improving computer system performance and energy efficiency, we urgently need new paths forward for expanding the capabilities of computers. Trading off accuracy for better performance and energy efficiency is an attractive option for many important and resource-hungry applications, including image and video processing, computer vision, machine learning, simulations, big data analytics, embedded systems, etc. For that reason, approximate computing has become a “hot topic,” with active research in computer architecture, programming languages, operating systems and user-facing areas such as ubiquitous computing and HCI.
Making approximate computing successful requires cooperation among all layers of the stack, from algorithms to programming languages to OSes to architecture to circuits, as well as system components like storage and networks. This workshop aims to bring together an interdisciplinary group of researchers to present and discuss thoughts and ideas on how to effectively exploit approximate computing.
Topics for WAX include:
- Hardware support for approximate computing
- Programming languages and compiler support for approximate computing
- Tools for writing, debugging, and testing approximate programs
- Modeling and understanding approximate computing opportunities and systems
- Applications amenable to approximation and domain-specific strategies
- Formal reasoning about programs with approximations
- Retrospectives on past approximate-computing work, including both reflections on your own past projects and reproduction of others’ results
- Position papers on approximate computing, potential, how it could fail, what we need to succeed, etc.
How to Participate
We invite participation in three forms: position papers, lightning talks, and discussion topics.
Peer-Reviewed Position Papers
The workshop will include a peer-reviewed program of short position papers. Papers can describe an early-stage research project, advocate an opinion about approximate computing, reflect on trends in the community, or reproduce someone else’s published result.
Position papers will go through a full peer-review process by a program committee of experts in approximate computing (see below). Papers will not be published in a proceedings, so they do not preclude future publication; instead, we will post PDFs on the workshop’s Web site. We also encourage authors of accepted papers to include artifacts—code, data, analysis scripts, etc.—which we will also host alongside the papers.
Accepted papers will be presented in short talks, around 5 to 15 minutes. We will not publish the paper in a formal proceedings. Instead, we will post PDFs of accepted papers on the workshop’s Web site. Authors are also encouraged to submit supporting material (code, data dumps, etc.) after acceptance, which we will also host. We especially encourage talks with live demos of applications and working tools.
Papers should use the formatting guidelines for SIGPLAN conferences (the
acmart format with the
sigplan two-column option) and not exceed 2 pages, excluding references. Review is single-blind, so please include authors’ names on the submitted PDF.
Submit your papers via HotCRP.
WAX will feature a session for short talks in the morning that present a single opinion, a nugget of an idea, or just food for thought. Speakers will have approximately 60 seconds. Talks will consist of two slides, one of which is a title slide (including at least the title itself and the speaker’s name, affiliation, and email address).
Lightning talks will not be peer reviewed. We will vet slides ahead of time to ensure that they are on topic, but there will be no full review process.
Please send slides for lightning talks (in .pdf or .ppt(x) format) to Hank Hoffmann (please use subject “WAX 2018 Lightning Talk Proposal”).
The WAX program will feature a debate among the attendees. We need your help building a list of controversial topics to serve as grist for the discussion mill.
Please submit a sentence or two about an open problem, philosophical question, or other thought you’d like to see discussed at the workshop. You can submit as many of these as you like. We’ll use these suggestions to set up a debate during the workshop.
