JETCAS Special Issue - Call for Papers: Cross-Layer Designs, Methodologies, and Systems to Enable Micro AI for On-Device Intelligence
Scope and Purpose
Artificial intelligence (AI) and robotics technology continue to have a major role in enabling future smart cities, transportation, surveillance, logistics, smart sensing, home health care, and medical technologies. These fields rely on large data-driven approaches and highly computation-intensive algorithms and tend to compute in the cloud and data centers. Local processing on an embedded device is often required to provide low latency and less dependence on the communication link for bandwidth and privacy/security concerns. However, processing locally on a device is very challenging due to limited memory storage and battery capacity. This proposal invites researchers to submit state-of-the-art computing methods through cross-layer design approaches in algorithms, architecture, hardware, and system integration, which will enable micro-intelligent systems to perform on-device sensor data analytics and various AI tasks at extremely low power.
In particular, this special issue seeks contributions encompassing the following broad scopes:
- AI model design: Novel reinforcement learning-based neural architecture search (NAS) methods generally aim to automatically explore the least computationally complex AI models that meet a targeted accuracy. Nevertheless, these searching methods seldom take into account the challenges of deploying the computationally-reduced AI model at the edge (hardware). This topic covers NAS methods that jointly explore efficient AI models including artificial neural networks (ANNs), deep neural networks (DNNs), recurrent neural networks (RNNs), and spiking neural networks (SNNs), etc., for feasible implementation on resource-bound hardware.
- Hardware design methodology: This topic covers novel approaches of task scheduling, tiling scheme, and data movement with various implementation styles and goals such as energy, power, and timing. Implementation styles such as in-memory computing, near-memory processing, and systolic array architecture, as well as techniques considering tradeoffs among computation and communication, the arrangement of processing engines, selection of fixed/floating-point/flexible hardware data width, and their impact on timing, power, performance, and energy efficiency are worthy of consideration in this topic.
- Memory hierarchy and data movement: In high dimensional AI models, the memory footprint dominates the silicon area, and the energy and delay overheads resulting from memory communication for implementing the AI models are significantly higher as compared to computation. Methods of efficiently implementing pruned or compressed AI models as well as different methods of data movement through different levels of the memory hierarchy (e.g., from DRAMs to SRAMs), and precise/flexible size allocation to different memory levels are among the issues to be addressed in this topic.
- Flexibility and reliability: While small AI models can be more conveniently implemented at the edge, the implementation of large models is still a challenging task for the resource-bound hardware. Meanwhile, the susceptibility of spiking neural networks to noise and event upsets is another challenge. This topic calls for novel methods considering flexible and reliable hardware design for versatile modern AI applications.
