Speaker embedding extractors significantly influence the performance of clustering-based speaker diarisation systems. Conventionally, only one embedding is extracted from each speech segment. However, because of the sliding window approach, a segment easily includes two or more speakers owing to speaker change points. This study proposes a novel embedding extractor architecture, referred to as a high-resolution embedding extractor (HEE), which extracts multiple high-resolution embeddings from each speech segment. Hee consists of a feature-map extractor and an enhancer, where the enhancer with the self-attention mechanism is the key to success. The enhancer of HEE replaces the aggregation process; instead of a global pooling layer, the enhancer combines relative information to each frame via attention leveraging the global context. Extracted dense frame-level embeddings can each represent a speaker. Thus, multiple speakers can be represented by different frame-level features in each segment. We also propose an artificially generating mixture data training framework to train the proposed HEE. Through experiments on five evaluation sets, including four public datasets, the proposed HEE demonstrates at least 10% improvement on each evaluation set, except for one dataset, which we analyse that rapid speaker changes less exist.

与变压器架构相关的自我监督学习的最新进展使自然语言处理（NLP）表现出极低的困惑。如此强大的模型需要越来越多的模型大小，因此需要大量的计算和内存足迹。在本文中，我们为大规模生成语言模型提出了一个有效的推理框架。作为减少模型大小的关键，我们通过不均匀的量化方法量化权重。然后，我们提出的称为NUQMM的量化矩阵乘法加速了，该内核可以在压缩比和准确性之间进行广泛的权衡。我们提出的NUQMM不仅减少了每个GPU的延迟，还减少了大LMS的全部推断，因为高压缩比（通过低位量化）减轻了最小所需的GPU数量。我们证明NUQMM可以将GPT-3（175b）模型的推理速度加速约14.4倍，并将能源消耗降低93％。

尽管存在扩散模型的各种变化，但将线性扩散扩散到非线性扩散过程中仅由几项作品研究。非线性效应几乎没有被理解，但是直觉上，将有更多有希望的扩散模式来最佳地训练生成分布向数据分布。本文介绍了基于分数扩散模型的数据自适应和非线性扩散过程。提出的隐式非线性扩散模型（INDM）通过结合归一化流量和扩散过程来学习非线性扩散过程。具体而言，INDM通过通过流网络利用\ textIt {litex {litex {littent Space}的线性扩散来隐式构建\ textIt {data Space}的非线性扩散。由于非线性完全取决于流网络，因此该流网络是形成非线性扩散的关键。这种灵活的非线性是针对DDPM ++的非MLE训练，将INDM的学习曲线提高到了几乎最大的似然估计（MLE）训练，事实证明，这是具有身份流量的INDM的特殊情况。同样，训练非线性扩散可以通过离散的步骤大小产生采样鲁棒性。在实验中，INDM实现了Celeba的最新FID。

Attempts to train a comprehensive artificial intelligence capable of solving multiple tasks have been impeded by a chronic problem called catastrophic forgetting.Although simply replaying all previous data alleviates the problem, it requires large memory and even worse, often infeasible in real world applications where the access to past data is limited. Inspired by the generative nature of the hippocampus as a short-term memory system in primate brain, we propose the Deep Generative Replay, a novel framework with a cooperative dual model architecture consisting of a deep generative model ("generator") and a task solving model ("solver"). With only these two models, training data for previous tasks can easily be sampled and interleaved with those for a new task. We test our methods in several sequential learning settings involving image classification tasks.

While humans easily recognize relations between data from different domains without any supervision, learning to automatically discover them is in general very challenging and needs many ground-truth pairs that illustrate the relations. To avoid costly pairing, we address the task of discovering cross-domain relations given unpaired data. We propose a method based on generative adversarial networks that learns to discover relations between different domains (DiscoGAN). Using the discovered relations, our proposed network successfully transfers style from one domain to another while preserving key attributes such as orientation and face identity.

We present a highly accurate single-image superresolution (SR) method. Our method uses a very deep convolutional network inspired by VGG-net used for ImageNet classification [19]. We find increasing our network depth shows a significant improvement in accuracy. Our final model uses 20 weight layers. By cascading small filters many times in a deep network structure, contextual information over large image regions is exploited in an efficient way. With very deep networks, however, convergence speed becomes a critical issue during training. We propose a simple yet effective training procedure. We learn residuals only and use extremely high learning rates (10 4 times higher than SRCNN [6]) enabled by adjustable gradient clipping. Our proposed method performs better than existing methods in accuracy and visual improvements in our results are easily noticeable.

Artificial intelligence methods including deep neural networks (DNN) can provide rapid molecular classification of tumors from routine histology with accuracy that matches or exceeds human pathologists. Discerning how neural networks make their predictions remains a significant challenge, but explainability tools help provide insights into what models have learned when corresponding histologic features are poorly defined. Here, we present a method for improving explainability of DNN models using synthetic histology generated by a conditional generative adversarial network (cGAN). We show that cGANs generate high-quality synthetic histology images that can be leveraged for explaining DNN models trained to classify molecularly-subtyped tumors, exposing histologic features associated with molecular state. Fine-tuning synthetic histology through class and layer blending illustrates nuanced morphologic differences between tumor subtypes. Finally, we demonstrate the use of synthetic histology for augmenting pathologist-in-training education, showing that these intuitive visualizations can reinforce and improve understanding of histologic manifestations of tumor biology.

在本文中，我们通过变异自动编码器（VAE）研究了基于弦的分子生成的问题，这些问题已经为人工智能的各种任务提供了一种流行的生成方法。我们提出了一个简单而有效的想法，以提高VAE的任务绩效。我们的主要思想是在共享单个编码器时维护多个解码器，即它是一种合奏技术。在这里，我们首先发现，由于合奏解码器的偏见在其自动回归推理下严重增加，因此每个解码器都可能没有有效。为了维持集合模型的较小偏见和差异，我们提出的技术是两倍：（a）为每个解码器采样不同的潜在变量（从共享编码器提供的估计平均值和差异）来鼓励解码器的多元化特征（b）在培训期间使用协作损失，以控制使用不同的潜在变量的解码器的汇总质量。在我们的实验中，提出的VAE模型特别表现出色，可从域外分布产生样品。

自动驾驶汽车和自主驾驶研究一直受到现代人工智能应用中主要有希望的前景。根据先进的驾驶员辅助系统（ADAS）的演变，自动驾驶车辆和自主驱动系统的设计变得复杂和安全至关重要。通常，智能系统同时和有效地激活ADAS功能。因此，必须考虑可靠的ADAS功能协调，安全地控制驱动系统。为了处理这个问题，本文提出了一种随机的对抗性模仿学习（RAIL）算法。铁路是一种新的无衍生仿制学习方法，用于具有各种ADAS功能协调的自主驾驶;因此，它模仿决策者的运作，可以使用各种ADAS功能控制自动驾驶。该方法能够培训涉及激光雷达数据的决策者，并控制多车道复合道环境中的自主驾驶。基于仿真的评估验证了所提出的方法实现了所需的性能。

According to the rapid development of drone technologies, drones are widely used in many applications including military domains. In this paper, a novel situation-aware DRL- based autonomous nonlinear drone mobility control algorithm in cyber-physical loitering munition applications. On the battlefield, the design of DRL-based autonomous control algorithm is not straightforward because real-world data gathering is generally not available. Therefore, the approach in this paper is that cyber-physical virtual environment is constructed with Unity environment. Based on the virtual cyber-physical battlefield scenarios, a DRL-based automated nonlinear drone mobility control algorithm can be designed, evaluated, and visualized. Moreover, many obstacles exist which is harmful for linear trajectory control in real-world battlefield scenarios. Thus, our proposed autonomous nonlinear drone mobility control algorithm utilizes situation-aware components those are implemented with a Raycast function in Unity virtual scenarios. Based on the gathered situation-aware information, the drone can autonomously and nonlinearly adjust its trajectory during flight. Therefore, this approach is obviously beneficial for avoiding obstacles in obstacle-deployed battlefields. Our visualization-based performance evaluation shows that the proposed algorithm is superior from the other linear mobility control algorithms.
