Descrizione Nowadays, Deep Learning represents the go-to-approach to solve recognition and prediction problems in a vast spectrum of application domains, including computer vision, time-series analysis, and natural language processing. For many of these tasks, deploying the model at the edge of the IoT provides several benefits with respect to a traditional cloud-centric approach, such as predictable response times and improved privacy. However, executing complex deep neural networks (DNN) on extreme-edge devices, such as low-power microcontrollers, is complicated by their tight constraints in terms of memory and energy consumption. Therefore, bringing "intelligence" at the IoT edge requires efficient architectures, that minimize the latency/energy consumption required for an inference, without sacrificing output quality (e.g., classification accuracy). Finding these architectures manually with "trial-and-error" is tedious and costly.
Therefore, in this thesis, the candidate will explore efficient automatic optimization algorithms able to explore a vast search space of possible neural network architectures, finding the ones that yield the best accuracy versus complexity trade-off. These methods are often referred to as Neural Architecture Search (NAS) tools. In particular, the candidate will focus on key aspects of a practical NAS tool, such as: i) accurately modeling of the target hardware platform's latency and energy consumption, ii) maximizing search efficiency and minimizing search time, iii) combining NAS with other deployment-oriented neural network optimization such as quantization and mixed-precision search.
The developed tool will be general and applicable across a wide spectrum of applications. In particular, the thesis candidate will evaulate the NAS on four tasks that are relevant for edge AI (image classification, visual wake-word, speech recognition and anomaly detection), which constitute the MLPerf Tiny standard benchmark suite. In terms of deployment target, the thesis will consider extreme-edge, ultra-low-power systems, such as RISC-V-based parallel clusters of general purpose cores (e.g. GreenWaves' GAP8 and GAP9).
