变异量子算法（VQA）在NISQ时代表现出巨大的潜力。在VQA的工作流程中，Ansatz的参数迭代更新以近似所需的量子状态。我们已经看到了各种努力，以较少的大门起草更好的安萨兹。在量子计算机中，栅极Ansatz最终将转换为控制信号，例如TransMons上的微波脉冲。并且对照脉冲需要精心校准，以最大程度地减少误差（例如过度旋转和旋转）。在VQA的情况下，此过程将引入冗余，但是VQAS的变异性能自然可以通过更新幅度和频率参数来处理过度旋转和重组的问题。因此，我们提出了PAN，这是一种用于VQA的天然脉冲ANSATZ GENTARATOR框架。我们生成具有可训练参数用于振幅和频率的天然脉冲ansatz。在我们提出的锅中，我们正在调整参数脉冲，这些脉冲在NISQ计算机上得到了内在支持。考虑到本机 - 脉冲ANSATZ不符合参数迁移规则，我们需要部署非级别优化器。为了限制发送到优化器的参数数量，我们采用了一种生成本机 - 脉冲ANSATZ的渐进式方式。实验是在模拟器和量子设备上进行的，以验证我们的方法。当在NISQ机器上采用时，PAN获得的延迟平均提高了86％。 PAN在H2和HEH+上的VQE任务分别能够达到99.336％和96.482％的精度，即使NISQ机器中有很大的噪声。

模拟/混合信号电路设计是整个芯片设计过程中最复杂，最耗时的阶段之一。由于芯片制造的各种过程，电压和温度（PVT）变化，模拟电路不可避免地会遭受性能降解。尽管在典型条件下自动化模拟电路设计方面已经有很多工作，但在探索在真实且不可预测的硅变化下探索可靠设计的研究有限。针对变化的自动模拟设计需要过度的计算和时间成本。为了应对挑战，我们提出了RobustanAlog，这是一个强大的电路设计框架，涉及优化过程中的变化信息。具体而言，不同变化下的电路优化被认为是一组任务。任务之间的相似之处是杠杆作用，并且可以缓解竞争以实现样本效率高的多任务培训。此外，Robustanalog根据每次迭代中当前的性能来修剪任务空间，从而导致进一步的模拟成本降低。这样，鲁棒可以迅速产生一组电路参数，这些电路参数满足各种变化的各种约束（例如增益，带宽，噪声...）。我们将Robustanalog与贝叶斯优化，进化算法和深层确定性策略梯度（DDPG）进行了比较，并证明Robustanalog可以将所需的优化时间显着减少14-30次。因此，我们的研究提供了一种处理各种真实硅条件的可行方法。

当系统的全面了解时然而，这种技术在灰盒设置中行动不成功，攻击者面部模板未知。在这项工作中，我们提出了一种具有新开发的目标函数的相似性的灰度逆势攻击（SGADV）技术。 SGAdv利用不同的评分来产生优化的对抗性实例，即基于相似性的对抗性攻击。这种技术适用于白盒和灰度箱攻击，针对使用不同分数确定真实或调用用户的身份验证系统。为了验证SGAdv的有效性，我们对LFW，Celeba和Celeba-HQ的面部数据集进行了广泛的实验，反对白盒和灰度箱设置的面部和洞察面的深脸识别模型。结果表明，所提出的方法显着优于灰色盒设置中的现有的对抗性攻击技术。因此，我们总结了开发对抗性示例的相似性基础方法可以令人满意地迎合去认证的灰度箱攻击场景。

量子噪声是嘈杂中间级量子（NISQ）计算机中的关键挑战。以前的缓解噪声的工作主要集中在门级或脉冲级噪声自适应编译。然而，有限的研究工作通过使量子电路本身对噪声具有更高的优化级别。我们提出了Quoutumnas，是变分电路和量子位映射的噪声自适应共同搜索的全面框架。变形量子电路是构建QML和量子仿真的有希望的方法。然而，由于大型设计空间和参数训练成本，找到最佳变分电路及其最佳参数是具有挑战性的。我们建议通过引入新的超级速度来解耦电路搜索和参数培训。超电路由多层预定的参数化栅极构成，并通过迭代采样和更新其的参数子集（Subcircuit）训练。它提供了从头开始培训的子通差形性能的准确估计。然后我们执行Subcircuit的演进共同搜索和其量子位映射。使用从超级电路继承的参数和使用真实设备噪声模型进行估计，估计子电路性能。最后，我们执行迭代栅极修剪和FineTuning以去除冗余栅极。在10个量子计算上广泛评估了12个QML和VQE基准，Quoutumnas显着优于基线。对于QML，Quoutumnas是第一个展示超过95％的2级，85％的4级和真实QC的32％的10级分类准确性。与UCCSD相比，它还实现了H2，H2O，LIH，CH4，BEH2上的VQE任务的最低特征值。我们还开源Quantumengine（https://github.com/mit-han-lab/pytorch-quantum），用于快速训练参数化量子电路，以促进未来的研究。

Self-driving cars need to understand 3D scenes efficiently and accurately in order to drive safely. Given the limited hardware resources, existing 3D perception models are not able to recognize small instances (e.g., pedestrians, cyclists) very well due to the low-resolution voxelization and aggressive downsampling. To this end, we propose Sparse Point-Voxel Convolution (SPVConv), a lightweight 3D module that equips the vanilla Sparse Convolution with the high-resolution point-based branch. With negligible overhead, this point-based branch is able to preserve the fine details even from large outdoor scenes. To explore the spectrum of efficient 3D models, we first define a flexible architecture design space based on SPVConv, and we then present 3D Neural Architecture Search (3D-NAS) to search the optimal network architecture over this diverse design space efficiently and effectively. Experimental results validate that the resulting SPVNAS model is fast and accurate: it outperforms the state-of-the-art MinkowskiNet by 3.3%, ranking 1 st on the competitive SemanticKITTI leaderboard upon publication. It also achieves 8× computation reduction and 3× measured speedup over MinkowskiNet still with higher accuracy. Finally, we transfer our method to 3D object detection, and it achieves consistent improvements over the one-stage detection baseline on KITTI.

Model compression is a critical technique to efficiently deploy neural network models on mobile devices which have limited computation resources and tight power budgets. Conventional model compression techniques rely on hand-crafted heuristics and rule-based policies that require domain experts to explore the large design space trading off among model size, speed, and accuracy, which is usually sub-optimal and time-consuming. In this paper, we propose AutoML for Model Compression (AMC) which leverage reinforcement learning to provide the model compression policy. This learning-based compression policy outperforms conventional rule-based compression policy by having higher compression ratio, better preserving the accuracy and freeing human labor. Under 4× FLOPs reduction, we achieved 2.7% better accuracy than the handcrafted model compression policy for VGG-16 on ImageNet. We applied this automated, push-the-button compression pipeline to MobileNet and achieved 1.81× speedup of measured inference latency on an Android phone and 1.43× speedup on the Titan XP GPU, with only 0.1% loss of ImageNet Top-1 accuracy.

In this paper, we propose a robust 3D detector, named Cross Modal Transformer (CMT), for end-to-end 3D multi-modal detection. Without explicit view transformation, CMT takes the image and point clouds tokens as inputs and directly outputs accurate 3D bounding boxes. The spatial alignment of multi-modal tokens is performed implicitly, by encoding the 3D points into multi-modal features. The core design of CMT is quite simple while its performance is impressive. CMT obtains 73.0% NDS on nuScenes benchmark. Moreover, CMT has a strong robustness even if the LiDAR is missing. Code will be released at https://github.com/junjie18/CMT.

Knowledge graphs (KG) have served as the key component of various natural language processing applications. Commonsense knowledge graphs (CKG) are a special type of KG, where entities and relations are composed of free-form text. However, previous works in KG completion and CKG completion suffer from long-tail relations and newly-added relations which do not have many know triples for training. In light of this, few-shot KG completion (FKGC), which requires the strengths of graph representation learning and few-shot learning, has been proposed to challenge the problem of limited annotated data. In this paper, we comprehensively survey previous attempts on such tasks in the form of a series of methods and applications. Specifically, we first introduce FKGC challenges, commonly used KGs, and CKGs. Then we systematically categorize and summarize existing works in terms of the type of KGs and the methods. Finally, we present applications of FKGC models on prediction tasks in different areas and share our thoughts on future research directions of FKGC.

Few Shot Instance Segmentation (FSIS) requires models to detect and segment novel classes with limited several support examples. In this work, we explore a simple yet unified solution for FSIS as well as its incremental variants, and introduce a new framework named Reference Twice (RefT) to fully explore the relationship between support/query features based on a Transformer-like framework. Our key insights are two folds: Firstly, with the aid of support masks, we can generate dynamic class centers more appropriately to re-weight query features. Secondly, we find that support object queries have already encoded key factors after base training. In this way, the query features can be enhanced twice from two aspects, i.e., feature-level and instance-level. In particular, we firstly design a mask-based dynamic weighting module to enhance support features and then propose to link object queries for better calibration via cross-attention. After the above steps, the novel classes can be improved significantly over our strong baseline. Additionally, our new framework can be easily extended to incremental FSIS with minor modification. When benchmarking results on the COCO dataset for FSIS, gFSIS, and iFSIS settings, our method achieves a competitive performance compared to existing approaches across different shots, e.g., we boost nAP by noticeable +8.2/+9.4 over the current state-of-the-art FSIS method for 10/30-shot. We further demonstrate the superiority of our approach on Few Shot Object Detection. Code and model will be available.

Graph Neural Networks (GNNs) have shown satisfying performance on various graph learning tasks. To achieve better fitting capability, most GNNs are with a large number of parameters, which makes these GNNs computationally expensive. Therefore, it is difficult to deploy them onto edge devices with scarce computational resources, e.g., mobile phones and wearable smart devices. Knowledge Distillation (KD) is a common solution to compress GNNs, where a light-weighted model (i.e., the student model) is encouraged to mimic the behavior of a computationally expensive GNN (i.e., the teacher GNN model). Nevertheless, most existing GNN-based KD methods lack fairness consideration. As a consequence, the student model usually inherits and even exaggerates the bias from the teacher GNN. To handle such a problem, we take initial steps towards fair knowledge distillation for GNNs. Specifically, we first formulate a novel problem of fair knowledge distillation for GNN-based teacher-student frameworks. Then we propose a principled framework named RELIANT to mitigate the bias exhibited by the student model. Notably, the design of RELIANT is decoupled from any specific teacher and student model structures, and thus can be easily adapted to various GNN-based KD frameworks. We perform extensive experiments on multiple real-world datasets, which corroborates that RELIANT achieves less biased GNN knowledge distillation while maintaining high prediction utility.
