Binaural rendering of ambisonic signals is of broad interest to virtual reality and immersive media. Conventional methods often require manually measured Head-Related Transfer Functions (HRTFs). To address this issue, we collect a paired ambisonic-binaural dataset and propose a deep learning framework in an end-to-end manner. Experimental results show that neural networks outperform the conventional method in objective metrics and achieve comparable subjective metrics. To validate the proposed framework, we experimentally explore different settings of the input features, model structures, output features, and loss functions. Our proposed system achieves an SDR of 7.32 and MOSs of 3.83, 3.58, 3.87, 3.58 in quality, timbre, localization, and immersion dimensions.

口语理解（SLU）将自动语音识别（ASR）和自然语言理解（NLU）视为一项统一任务，通常遭受数据稀缺。我们基于元辅助学习来利用ASR和NLU联合培训方法，通过仅利用大量的语音数据来提高低资源SLU任务的性能。这种方法的一个明显优势是，它提供了一个灵活的框架来实施低资源的SLU训练任务，而无需访问任何进一步的语义注释。特别是，NLU模型被视为标签生成网络，以预测文本的意图和插槽标签。多任务网络网络从语音同步训练ASR任务和SLU任务；标签生成网络的预测作为语义目标传递到多任务网络。通过公共CATSLU数据集的实验证明了所提出的算法的效率，该数据集对下游NLU任务产生了更合适的ASR假设。

基于标记的关系三重提取方法最近引起了日益增长的研究。然而，大多数这些方法采用单向提取框架，首先提取所有受试者，然后基于提取的受试者同时提取物体和关系。该框架具有明显的缺陷，即对受试者的提取结果太敏感。为了克服这种缺陷，我们提出了一种基于双向提取框架的方法，该方法基于从两个互补方向提取的实体对提取三维。具体地，我们首先从两个平行方向提取所有可能的主题对象对。这两个提取方向通过共享编码器组件连接，因此从一个方向的提取特征可以流到另一个方向，反之亦然。通过这种方式，两个方向的提取可以促进和相互补充。接下来，我们通过双重模型分配每个实体对的所有可能的关系。在培训期间，我们观察到股份结构将导致融合率不一致问题，这是对绩效有害的。因此，我们提出了一个享有意识的学习机制来解决它。我们在多个基准数据集中评估所提出的模型。广泛的实验结果表明，所提出的模型非常有效，它在所有这些数据集中实现了最先进的结果。此外，实验表明，所提出的双向提取框架和股感的学习机制都具有良好的适应性，可用于改善基于标记的其他标记的方法的性能。我们工作的源代码可用于：https：//github.com/neukg/birte。

尽管现有的机器阅读理解模型在许多数据集上取得了迅速的进展，但它们远非强劲。在本文中，我们提出了一个面向理解的机器阅读理解模型，以解决三种鲁棒性问题，这些问题过于敏感，稳定性和泛化。具体而言，我们首先使用自然语言推理模块来帮助模型了解输入问题的准确语义含义，以解决过度敏感性和稳定性的问题。然后，在机器阅读理解模块中，我们提出了一种记忆引导的多头注意方法，该方法可以进一步很好地理解输入问题和段落的语义含义。第三，我们提出了一种多语言学习机制来解决概括问题。最后，这些模块与基于多任务学习的方法集成在一起。我们在三个旨在衡量模型稳健性的基准数据集上评估了我们的模型，包括Dureader（健壮）和两个与小队相关的数据集。广泛的实验表明，我们的模型可以很好地解决上述三种鲁棒性问题。而且，即使在某些极端和不公平的评估下，它也比所有这些数据集中所有这些数据集的最先进模型的结果要好得多。我们工作的源代码可在以下网址获得：https：//github.com/neukg/robustmrc。

仿制学习（IL）是一种有效的学习范例，利用代理和环境之间的交互。它不需要显式奖励信号，而是尝试使用专家演示恢复所需的策略。通常，IL方法可以分类为行为克隆（BC）和逆钢筋学习（IRL）。在这项工作中，提出了一种基于概率密度估计的新型奖励功能，用于IRL，这可以显着降低现有IRL方法的复杂性。此外，我们证明，只要确定性，我们源自奖励函数的理论上最佳政策与专家政策相同。因此，可以优雅地将IRL问题变为概率密度估计问题。基于所提出的奖励函数，我们展示了一个“观看 - 尝试学习”样式框架命名概率密度估计的基于仿真学习（PDEIL），其可以在离散和连续的动作空间中工作。最后，在健身房环境中的综合实验表明，Pdeil比现有算法恢复靠近地面真理的奖励更有效。

Temporal action proposal generation is an challenging and promising task which aims to locate temporal regions in real-world videos where action or event may occur. Current bottom-up proposal generation methods can generate proposals with precise boundary, but cannot efficiently generate adequately reliable confidence scores for retrieving proposals. To address these difficulties, we introduce the Boundary-Matching (BM) mechanism to evaluate confidence scores of densely distributed proposals, which denote a proposal as a matching pair of starting and ending boundaries and combine all densely distributed BM pairs into the BM confidence map. Based on BM mechanism, we propose an effective, efficient and end-to-end proposal generation method, named Boundary-Matching Network (BMN), which generates proposals with precise temporal boundaries as well as reliable confidence scores simultaneously. The two-branches of BMN are jointly trained in an unified framework. We conduct experiments on two challenging datasets: THUMOS-14 and ActivityNet-1.3, where BMN shows significant performance improvement with remarkable efficiency and generalizability. Further, combining with existing action classifier, BMN can achieve stateof-the-art temporal action detection performance.

Masked image modeling (MIM) performs strongly in pre-training large vision Transformers (ViTs). However, small models that are critical for real-world applications cannot or only marginally benefit from this pre-training approach. In this paper, we explore distillation techniques to transfer the success of large MIM-based pre-trained models to smaller ones. We systematically study different options in the distillation framework, including distilling targets, losses, input, network regularization, sequential distillation, etc, revealing that: 1) Distilling token relations is more effective than CLS token- and feature-based distillation; 2) An intermediate layer of the teacher network as target perform better than that using the last layer when the depth of the student mismatches that of the teacher; 3) Weak regularization is preferred; etc. With these findings, we achieve significant fine-tuning accuracy improvements over the scratch MIM pre-training on ImageNet-1K classification, using all the ViT-Tiny, ViT-Small, and ViT-base models, with +4.2%/+2.4%/+1.4% gains, respectively. Our TinyMIM model of base size achieves 52.2 mIoU in AE20K semantic segmentation, which is +4.1 higher than the MAE baseline. Our TinyMIM model of tiny size achieves 79.6% top-1 accuracy on ImageNet-1K image classification, which sets a new record for small vision models of the same size and computation budget. This strong performance suggests an alternative way for developing small vision Transformer models, that is, by exploring better training methods rather than introducing inductive biases into architectures as in most previous works.

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.

Dataset distillation has emerged as a prominent technique to improve data efficiency when training machine learning models. It encapsulates the knowledge from a large dataset into a smaller synthetic dataset. A model trained on this smaller distilled dataset can attain comparable performance to a model trained on the original training dataset. However, the existing dataset distillation techniques mainly aim at achieving the best trade-off between resource usage efficiency and model utility. The security risks stemming from them have not been explored. This study performs the first backdoor attack against the models trained on the data distilled by dataset distillation models in the image domain. Concretely, we inject triggers into the synthetic data during the distillation procedure rather than during the model training stage, where all previous attacks are performed. We propose two types of backdoor attacks, namely NAIVEATTACK and DOORPING. NAIVEATTACK simply adds triggers to the raw data at the initial distillation phase, while DOORPING iteratively updates the triggers during the entire distillation procedure. We conduct extensive evaluations on multiple datasets, architectures, and dataset distillation techniques. Empirical evaluation shows that NAIVEATTACK achieves decent attack success rate (ASR) scores in some cases, while DOORPING reaches higher ASR scores (close to 1.0) in all cases. Furthermore, we conduct a comprehensive ablation study to analyze the factors that may affect the attack performance. Finally, we evaluate multiple defense mechanisms against our backdoor attacks and show that our attacks can practically circumvent these defense mechanisms.

Blind image quality assessment (BIQA) remains challenging due to the diversity of distortion and image content variation, which complicate the distortion patterns crossing different scales and aggravate the difficulty of the regression problem for BIQA. However, existing BIQA methods often fail to consider multi-scale distortion patterns and image content, and little research has been done on learning strategies to make the regression model produce better performance. In this paper, we propose a simple yet effective Progressive Multi-Task Image Quality Assessment (PMT-IQA) model, which contains a multi-scale feature extraction module (MS) and a progressive multi-task learning module (PMT), to help the model learn complex distortion patterns and better optimize the regression issue to align with the law of human learning process from easy to hard. To verify the effectiveness of the proposed PMT-IQA model, we conduct experiments on four widely used public datasets, and the experimental results indicate that the performance of PMT-IQA is superior to the comparison approaches, and both MS and PMT modules improve the model's performance.
