Single-image 3D human reconstruction aims to reconstruct the 3D textured surface of the human body given a single image. While implicit function-based methods recently achieved reasonable reconstruction performance, they still bear limitations showing degraded quality in both surface geometry and texture from an unobserved view. In response, to generate a realistic textured surface, we propose ReFu, a coarse-to-fine approach that refines the projected backside view image and fuses the refined image to predict the final human body. To suppress the diffused occupancy that causes noise in projection images and reconstructed meshes, we propose to train occupancy probability by simultaneously utilizing 2D and 3D supervisions with occupancy-based volume rendering. We also introduce a refinement architecture that generates detail-preserving backside-view images with front-to-back warping. Extensive experiments demonstrate that our method achieves state-of-the-art performance in 3D human reconstruction from a single image, showing enhanced geometry and texture quality from an unobserved view.

Graph convolutional neural networks (GCNs) have emerged as a key technology in various application domains where the input data is relational. A unique property of GCNs is that its two primary execution stages, aggregation and combination, exhibit drastically different dataflows. Consequently, prior GCN accelerators tackle this research space by casting the aggregation and combination stages as a series of sparse-dense matrix multiplication. However, prior work frequently suffers from inefficient data movements, leaving significant performance left on the table. We present GROW, a GCN accelerator based on Gustavson's algorithm to architect a row-wise product based sparse-dense GEMM accelerator. GROW co-designs the software/hardware that strikes a balance in locality and parallelism for GCNs, achieving significant energy-efficiency improvements vs. state-of-the-art GCN accelerators.

诸如GELU，LIZESION和SOFTMAX之类的非线性操作是变压器模型的必备且昂贵的构建块。有几种先前的作品简化了这些操作，使用查找表或整数计算，但是这种近似值遭受了更低的精度或相当大的硬件成本，并且长期延迟。本文提出了一种精确且硬件友好的近似框架，用于高效变压器推断。我们的框架采用简单的神经网络作为通用近似器，其结构等效地转换成LUT。拟议的框架，称为NN-LUT可以准确地更换流行伯特模型中的所有非线性操作，在面积，功耗和延迟中显着降低。

分配和验证国际公认的商品代码（HS编码）的任务是贸易货物的是海关办公室的关键职能之一。这一决定对于进口商和出口商至关重要，因为它决定了关税率。但是，类似于法官作出的法院决定，即使对于经验丰富的海关官员，任务也可能是非琐碎的。目前的论文提出了一个深入的学习模式，以协助这一看似挑战HS代码分类。与韩国海关服务一起，我们建立了基于科电的决策模型，该决策模型建议了HS代码的最有可能的标题和副标题（即，前四位和六位数）。在129,084件之前的情况下评估显示，我们模型的前3个建议在分类265个副标题方面的准确性为95.5％。这个有希望的结果意味着算法可以通过协助HS代码分类任务来减少海关官员所采取的时间和精力。

基于会话的建议旨在根据持续的会话预测用户的下一个行为。先前的作品是将会话建模为一系列项目的变量长度，并学习单个项目和汇总会话的表示。最近的研究应用了图形神经网络，具有注意机制，通过将会话建模为图形结构化数据来捕获复杂的项目过渡和依赖性。但是，他们仍然在数据和学习方法方面面临着根本的挑战，例如稀疏监督信号和会议中的嘈杂互动，从而导致次优性能。在本文中，我们提出了SR-GCL，这是一个基于会话建议的新型对比学习框架。作为对比学习的关键组成部分，我们提出了两种全球环境增强的数据增强方法，同时保持原始会话的语义。与其他最先进的方法相比，两个现实世界电子商务数据集的广泛实验结果证明了SR-GCL的优势。

机器学习（ML）的广泛部署正在引起严重的关注，以保护为收集培训数据做出贡献的用户的隐私。差异隐私（DP）作为保护保护的实用标准，在行业中迅速获得势头。尽管DP的重要性，但是在计算机系统社区中，几乎没有探索这种新兴ML算法对系统设计的影响。在这项工作中，我们对名为DP-SGD的最先进的私人ML培训算法进行了详细的工作量表征。我们发现了DP-SGD的几种独特属性（例如，其高内存能力和计算需求与非私人ML），从而引起其关键瓶颈。基于我们的分析，我们提出了一个名为Diva的差异私有ML的加速器，该加速器在计算利用率方面具有显着改善，从而导致2.6倍的能量效率与常规收缩期阵列。

迅速探索随机树（RRT）已申请自动停车，因为迅速解决高维运动规划，易于反映约束。然而，规划时间通过延伸狭窄的停车点而无需碰撞而增加。为了减少规划时间，提出了目标树算法，用了向后停车路径的集合（目标树）代替RRT中的停车目标。然而，它由圆形和直线路径组成，并且由于曲率不连续性，自主车辆无法准确停放。此外，规划时间在复杂的环境中增加;障碍物可以阻挡向后路径。因此，本文介绍了复杂停车环境的连续曲率目标树算法。首先，目标树包括薄帘路径，以解决这种曲率不连续性。其次，为了进一步减少计划时间，定义了成本函数以构建考虑障碍物的目标树。与最佳变型RRT集成并搜索到达后向路径中的最短路径，所提出的算法在采样时间增加时获得近最佳路径。实验结果在真实环境中表明车辆更加准确地停放，并且连续曲率路径比与其他基于样品的算法所获得的那些获得更高的成功率。

The 3D-aware image synthesis focuses on conserving spatial consistency besides generating high-resolution images with fine details. Recently, Neural Radiance Field (NeRF) has been introduced for synthesizing novel views with low computational cost and superior performance. While several works investigate a generative NeRF and show remarkable achievement, they cannot handle conditional and continuous feature manipulation in the generation procedure. In this work, we introduce a novel model, called Class-Continuous Conditional Generative NeRF ($\text{C}^{3}$G-NeRF), which can synthesize conditionally manipulated photorealistic 3D-consistent images by projecting conditional features to the generator and the discriminator. The proposed $\text{C}^{3}$G-NeRF is evaluated with three image datasets, AFHQ, CelebA, and Cars. As a result, our model shows strong 3D-consistency with fine details and smooth interpolation in conditional feature manipulation. For instance, $\text{C}^{3}$G-NeRF exhibits a Fr\'echet Inception Distance (FID) of 7.64 in 3D-aware face image synthesis with a $\text{128}^{2}$ resolution. Additionally, we provide FIDs of generated 3D-aware images of each class of the datasets as it is possible to synthesize class-conditional images with $\text{C}^{3}$G-NeRF.

Cellular automata (CA) captivate researchers due to teh emergent, complex individualized behavior that simple global rules of interaction enact. Recent advances in the field have combined CA with convolutional neural networks to achieve self-regenerating images. This new branch of CA is called neural cellular automata [1]. The goal of this project is to use the idea of idea of neural cellular automata to grow prediction machines. We place many different convolutional neural networks in a grid. Each conv net cell outputs a prediction of what the next state will be, and minimizes predictive error. Cells received their neighbors' colors and fitnesses as input. Each cell's fitness score described how accurate its predictions were. Cells could also move to explore their environment and some stochasticity was applied to movement.

There is a dramatic shortage of skilled labor for modern vineyards. The Vinum project is developing a mobile robotic solution to autonomously navigate through vineyards for winter grapevine pruning. This necessitates an autonomous navigation stack for the robot pruning a vineyard. The Vinum project is using the quadruped robot HyQReal. This paper introduces an architecture for a quadruped robot to autonomously move through a vineyard by identifying and approaching grapevines for pruning. The higher level control is a state machine switching between searching for destination positions, autonomously navigating towards those locations, and stopping for the robot to complete a task. The destination points are determined by identifying grapevine trunks using instance segmentation from a Mask Region-Based Convolutional Neural Network (Mask-RCNN). These detections are sent through a filter to avoid redundancy and remove noisy detections. The combination of these features is the basis for the proposed architecture.
