• Jan 2022: Network Augmentation for Tiny Deep Learning  is accepted by ICLR’22.  Training tiny models are different from large models: rather than augmenting the data, we should augment the model, since tiny models tend to suffer from limited capacity. To alleviate this issue, NetAug augments the network (reverse dropout) instead of inserting noise into the dataset or the network. It puts the tiny model into larger models and encourages it to work as a sub-model of larger models to get extra supervision, in addition to functioning as an independent model. paper 

   

• Jan 2022: TorchSparse: Efficient Point Cloud Inference Engine is accepted by MLSys’22. The sparse and irregular nature of point clouds poses severe challenges to running sparse CNNs efficiently; existing sparse acceleration techniques for 2D images do not translate to 3D point clouds. We introduce TorchSparse, a high-performance point cloud inference engine that accelerates the sparse convolution computation on GPUs. TorchSparse directly optimizes the two bottlenecks of sparse convolution: data movement and irregular computation. It optimizes the data orchestration by quantization and fused locality-aware memory access, reducing the memory movement cost by 2.7x. It also adopts adaptive MM grouping to trade computation for better regularity, achieving 1.4-1.5x speedup for matrix multiplication. 

   

• Dec 2021: MCUNet-v2: Memory Efficient Inference for Tiny Deep Learning is presented at NeurIPS’21. Tiny deep learning on microcontroller units (MCUs) is challenging due to the limited memory size. The imbalanced memory distribution CNN exacerbates the issue: the first several blocks have an order of magnitude larger memory usage than the rest of the network. We propose a patch-by-patch inference scheduling, which operates only on a small spatial region of the feature map and significantly cuts down the peak memory. However, naive implementation brings overlapping patches and computation overhead. We further propose network redistribution to shift the receptive field and FLOPs to the later stage and reduce the computation overhead. MCUNetV2 sets a record ImageNet accuracy on MCU (71.8%), and achieves >90% accuracy on the visual wake words dataset under only 32kB SRAM. MCUNetV2 also unblocks object detection on tiny devices, achieving 16.9% higher mAP on Pascal VOC compared to the state-of-the-art result. Our study largely addressed the memory bottleneck in tinyML and paved the way for various vision applications beyond classification but also detection. paper / website / slides / demo / demo2 / MIT News / TechTalks

   

• Dec 2021: Delayed Gradient Averaging: Tolerate the Communication Latency for Federated Learning is presented at NeurIPS’21. Federated learning suffers from high communication latency. We propose Delayed Gradient Averaging (DGA), which delays the averaging step to allow local computation run ahead of communication. We theoretically prove that DGA attains a similar convergence rate as FedAvg, and empirically show that our algorithm can tolerate high network latency without compromising accuracy. DGA is implemented on 16-node Raspberry Pi cluster. With both IID and non-IID partitions, and show DGA can bring 2.55× to 4.07× speedup. paper / website / slides / poster
  

   

• Dec 2021: NAAS: Neural Accelerator Architecture Search is presented at DAC’21. We proposed a novel data-driven approach for AI-designed AI accelerator. Such data-driven method can find knowledge that is difficult to be explicitly expressed by human and can efficiently scale. Design spaces of hardware, compiler, and neural networks are tightly entangled, joint-optimization is better than separate optimization. Given the huge design space, data-driven approach is desirable. With the same runtime, machine learning methods can explore more data points than human designers. NAAS proposes a data-driven, automatic design space exploration of neural accelerator architectures that outperforms human design. paper / website / slides / video
  

   

• Oct 2021: QuantumNAS: Noise-Adaptive Search for Robust Quantum Circuits to appear at HPCA’22. Quantum noise is the key challenge in Noisy Intermediate-Scale Quantum (NISQ) computers. We propose QuantumNAS (NAS: Noise-Adaptive Search), a comprehensive framework for noise-adaptive co-search of the variational circuit and qubit mapping. Enlightened by the Once-for-all network, QuantumNAS decouples the circuit search and parameter training by introducing a novel SuperCircuit, followed by evolutionary co-search of SubCircuit and its qubit mapping. Finally, we perform iterative gate pruning and finetuning to remove redundant gates and reduce noise. QuantumNAS is the first to demonstrate over 95% 2-class, 85% 4-class, and 32% 10-class classification accuracy on real QC. It also achieves the lowest eigenvalue for VQE tasks. We open-source TorchQuantum for fast training of parameterized quantum circuits to facilitate future research. paper / qmlsys website

   

• Oct 2021: PointAcc: Efficient Point Cloud Accelerator is presented at International Symposium on Microarchitecture (MICRO’21) . Deep learning on point clouds plays a vital role in a wide range of applications such as autonomous driving. Compared to projecting the point cloud to 2D space, directly processing 3D point cloud yields higher accuracy and lower #MACs. However, the extremely sparse nature of point cloud poses challenges to hardware acceleration. PointAcc proposes an versatile sorting engine to determine the nonzero input-output pairs, streams the sparse computation with reconfigurable caching, and temporally fuses consecutive dense layers to reduce the memory footprint. Co-designed with light-weight neural networks, PointAcc rivals the prior art by 100X speedup with 9.1% higher accuracy for semantic segmentation. paper / website / slides / talk / lightning talk

When deployed on edge devices, our model achieves 6-12× speedup, enabling interactive image editing on mobile devices. paper / website / video / code

• March 2019: HAQ: Hardware-aware Automated Quantization with Multi-precision is accepted by CVPR’19  as oral presentation. HAQ leverages reinforcement learning to automatically determine the quantization policy (bit width per layer), and we take the hardware accelerator’s feedback in the design loop. Rather than relying on proxy signals such as FLOPs and model size, we employ a hardware simulator to generate direct feedback (both latency and energy) to the RL agent. Compared with conventional methods, our framework is fully automated and can specialize the quantization policy for different neural network architectures and hardware architectures. 
  So far, ProxylessNAS [ICLR’19] => AMC [ECCV’18] => HAQ [CVPR’19] forms a pipeline of  efficient AutoML.
