由长期记忆复发网络（LSTM-RNN）和变压器代表的最先进的神经网络语言模型（NNLMS）和变压器变得非常复杂。当获得有限的培训数据时，它们容易过度拟合和泛化。为此，本文提出了一个总体完整的贝叶斯学习框架，其中包含三种方法，以说明LSTM-RNN和Transformer LMS的潜在不确定性。分别使用贝叶斯，高斯过程和变异LSTM-RNN或变压器LMS对其模型参数，神经激活的选择和隐藏输出表示的不确定性。有效的推理方法被用来自动选择使用神经体系结构搜索的最佳网络内部组件作为贝叶斯学习。还使用了最少数量的蒙特卡洛参数样本。这些允许贝叶斯NNLM培训和评估中产生的计算成本最小化。实验是针对两项任务进行的：AMI符合转录和牛津-BBC唇读句子2（LRS2）使用最先进的LF-MMI培训的有效的TDNN系统重叠的语音识别，具有数据增强，扬声器的适应和多种音频，频道横梁成形以进行重叠的语音。基线LSTM-RNN和Transformer LMS具有估计的模型参数和辍学正则化的一致性改进，就困惑性和单词错误率（WER）获得了两项任务。特别是，在LRS2数据上，在基线LSTM-RNN和Transformer LMS中，在贝叶斯NNLMS及其各自的Baselines之间的模型组合后，在基线LSTM-RNN和Transferes LMS上分别获得了最高1.3％和1.2％的绝对降低（相对12.1％和11.3％）。 。

阿尔茨海默氏病（AD）的早期诊断对于促进预防性护理和延迟进展至关重要。基于语音的自动广告筛选系统为其他临床筛查技术提供了一种非侵入性，更可扩展的替代方案。此类专业数据的稀缺性会导致模型选择和特征学习的不确定性。为此，本文调查了功能和模型组合方法的使用，以改善Bert和Roberta预先训练的文本编码有限数据的域微调的鲁棒性，然后在将结果的嵌入功能馈入后端分类器集合之前通过多数投票制定最终的广告检测决定。在ADRESS20挑战数据集上进行的实验表明，使用模型和功能组合在系统开发中获得了一致的性能改进。使用手册和ASR语音转录本在ADRESS20测试集上分别获得了91.67％和93.75％的最先进的AD检测精度，该准确的准确性是由48位老年人组成的。

阿尔茨海默氏病（AD）的早期诊断对于促进预防性护理以延迟进一步发展至关重要。本文介绍了建立在痴呆症Pitt copus上的基于最新的构象识别系统以自动检测的开发。通过纳入一组有目的设计的建模功能，包括基于域搜索的自动配置特异性构象异构体超参数除外，还包括基于速度扰动和基于规格的数据增强训练的基线构象体系统可显着改善。使用学习隐藏单位贡献（LHUC）的细粒度老年人的适应性；以及与混合TDNN系统的基于两次通行的跨系统逆转。在48位老年人的评估数据上获得了总体单词错误率（相对34.8％）的总体单词错误率（相对34.8％）。使用最终系统的识别输出来提取文本特征，获得了最佳的基于语音识别的AD检测精度为91.7％。

混合动力和端到端（E2E）自动语音识别（ASR）系统之间的基本建模差异在其中创造了巨大的多样性和互补性。本文研究了混合TDNN和构型E2E ASR系统的基于多通的逆转和交叉适应系统组合方法。在多通恢复中，最先进的混合动力LF-MMI训练有素的CNN-TDNN系统具有速度扰动，规格和贝叶斯学习隐藏单元供款（LHUC）扬声器的适应器，以在被恢复之前产生初始的N-tesk输出由扬声器适应构象异构体系统，使用2向跨系统得分插值。在交叉适应中，混合CNN-TDNN系统适用于构象异构体系统的1好的输出，反之亦然。在300小时的总机语料库上进行的实验表明，使用两种系统组合方法中的任何一个得出的组合系统都超过了单个系统。在NIST HUB5'00，RT03和RT03和RT02评估数据。

关节特征本质上是声信号失真的不变，并且已成功地纳入了为正常语音设计的自动语音识别（ASR）系统。它们在非典型任务领域（例如老年人和跨语言的言语无序）的实际应用通常受到从目标扬声器收集此类专家数据的困难。本文介绍了一种跨域和跨语性A2A反演方法，该方法利用了A2A模型中24小时TAL Corpus的平行音频，视觉和超声舌成像（UTI）数据，然后进行交叉训练和交叉训练。语言适用于两种语言的三个数据集：英语dementiabank pitt和antonese JCCOCC MOCA老年演讲Corpora;以及英语Torgo违反语音数据，以产生基于UTI的发音特征。 Experiments conducted on three tasks suggested incorporating the generated articulatory features consistently outperformed the baseline hybrid TDNN and Conformer based end-to-end systems constructed using acoustic features only by statistically significant word error rate or character error rate reductions up to 2.64%, 1.92% and数据增强和说话者适应后，绝对4.17％，7.89％和13.28％相对1.21％。

尽管针对正常语音的自动语音识别（ASR）技术取得了迅速的进展，但迄今为止，准确认识违反障碍和老年语音仍然是高度挑战的任务。由于这些用户中经常发现的移动性问题，很难为ASR系统开发收集大量此类数据。为此，数据增强技术起着至关重要的作用。与现有的数据增强技术相反，仅修改光谱轮廓的说话速率或整体形状，使用一组新颖的扬声器依赖（SD）生成对抗网络（Gan ）本文基于数据增强方法。这些既可以灵活地允许：a）在可用的语音数据可用时修改时间或速度的正常语音光谱，并更接近受损说话者的扬声器； b）对于非平行数据，SVD分解了正常语音频谱基础特征，要转换为目标老年人说话者的特征，然后再与时间基础重组以生成最先进的TDNN的增强数据和构象体ASR系统培训。实验是针对四个任务进行的：英语Uapseech和Torgo违反语音语音Corpora；英国痴呆症皮特和广东话JCCOCC MOCA老年语音数据集。所提出的基于GAN的数据增强方法始终优于基线速度扰动方法，最多可在Torgo和Dementiabank数据上降低4.91％和3.0％的绝对速度（相对相对9.61％和6.4％）。应用基于LHUC的扬声器适应后，保留了一致的性能改进。

经常性神经网络语言模型（RNNLMS）的高存储器消耗和计算成本限制了它们对资源受限设备的更广泛的应用。近年来，能够产生极低比特压缩的神经网络量化技术，例如二值化的RNNLMS正在获得增加的研究兴趣。直接培训量化神经网络是困难的。通过将量化的RNNLMS培训作为优化问题的制定，使用乘法器（ADMM）的交替方向方法从头开始训练量化RNNLMS的新方法。使用捆绑的低比特量化表，此方法还可以灵活地调整压缩率和模型性能之间的权衡。两项任务的实验：Penn TreeBank（PTB）和交换机（SWBD）建议所提出的ADMM量化在全精密基线RNNLMS上实现了高达31次的模型尺寸压缩因子。还获得了在基线二值化RNNLM量化上模型训练中的5倍的更快收敛性。索引项：语言模型，经常性神经网络，量化，乘法器的交替方向方法。

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.

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.
