未来几年物联网设备计数的预期增加促使有效算法的开发，可以帮助其有效管理，同时保持功耗低。在本文中，我们提出了一种智能多通道资源分配算法，用于Loradrl的密集Lora网络，并提供详细的性能评估。我们的结果表明，所提出的算法不仅显着提高了Lorawan的分组传递比（PDR），而且还能够支持移动终端设备（EDS），同时确保较低的功耗，因此增加了网络的寿命和容量。}大多数之前作品侧重于提出改进网络容量的不同MAC协议，即Lorawan，传输前的延迟等。我们展示通过使用Loradrl，我们可以通过Aloha \ TextColor {Black}与Lorasim相比，我们可以实现相同的效率LORA-MAB在将复杂性从EDS移动到网关的同时，因此使EDS更简单和更便宜。此外，我们在大规模的频率干扰攻击下测试Loradrl的性能，并显示其对环境变化的适应性。我们表明，与基于学习的技术相比，Loradrl的输出改善了最先进的技术的性能，从而提高了PR的500多种\％。

多语言语音识别已引起大幅关注，作为补偿低资源语言数据稀缺性的有效方法。端到端（E2E）建模比常规混合系统优选，这主要是由于没有词典要求。但是，在有限的数据方案中，混合DNN-HMM仍然优于E2E模型。此外，手动词典创建的问题已通过公开训练的素式训练型（G2P）（G2P）和多种语言的IPA音译来缓解。在本文中，在低资源语言的多语言设置中提出了一种混合DNN-HMM声学模型的新型方法。针对目标语言语言信号的不同单语言模型的后验分布融合在一起。为每个源目标语言对训练了一个单独的回归神经网络，以将后者从源声学模型转换为目标语言。与ASR培训相比，这些网络需要非常有限的数据。与多语言和单语基线相比，后融合的相对增益分别为14.65％和6.5％。跨语性模型融合表明，无需使用依赖语言的ASR的后代，就可以实现可比的结果。

多语言自动语音识别（ASR）系统大多受益于低资源语言，但相对于单语言对应物，多种语言的性能下降。有限的研究集中在理解多语言语音识别设置中的语言行为。在本文中，提出了一种新型的数据驱动方法来研究跨语性的声学表达相似性。该技术衡量了各种单语言模型与目标语音信号的后验分布之间的相似性。深度神经网络被训练为映射网络，以将分布从不同的声学模型转换为直接比较的形式。分析观察到，语言接近性无法通过集合音素的体积真正估计。对拟议的映射网络的熵分析表明，具有较小重叠的语言可以更适合跨语性转移，因此在多语言设置中更有益。最后，提出的后验变换方法被利用为目标语言的单语模型融合。比单语言对应物的相对提高约为8％。

本文提出了一类具有多项式非线性的非线性系统的基于数据驱动的集基估计算法。使用系统的输入输出数据，所提出的方法实时计算，保证包含系统状态的集合。尽管假设系统是多项式类型，但不需要知道精确的多项式函数及其系数。为此，估算器依赖于离线和在线阶段。离线阶段利用过去的输入输出数据来估计多项式系统的一组可能的系数。然后，使用该估计的系数和关于系统的侧面信息，在线阶段提供了对状态的集合估计。最后，通过其对SIR（易感，受感染的）的流行病模型的应用来评估所提出的方法。

尽管用被动传感器的深度提取的深度提取可以通过深度学习的显着改善，但是如果在训练过程中未观察到的环境，这些方法可能无法获得正确的深度。在部署时神经网络训练的在线改编，通过自我监督的学习提供了方便的解决方案，因为网络可以从不外部监督的情况下从部署的场景中学习。但是，在线适应会导致神经网络忘记了过去。因此，过去的培训浪费了，如果网络观察到过去的场景，该网络将无法提供良好的结果。这项工作涉及实用的在线适应，其中输入是在线且与时间相关的，并且培训是完全自欺欺人的。提出了没有任务界限的基于正规化和基于重播的方法，以避免在适应在线数据时灾难性遗忘。已经努力使建议的方法适合实际使用。我们将我们的方法应用于结构 - 动作和立体声深度估计。我们评估了包括室外，室内和合成场景在内的不同公共数据集的方法。与最近的方法相比，结构上的定性和定量结果既显示出较高的遗忘以及适应性的表现。此外，与在线适应进行微调相比，提出的方法会忽略不计的间接费用，这在可塑性，稳定性和适用性方面是一个适当的选择。当神经网络不受监督而不断学习时，提出的方法与人工通用情报范式更加内联。源代码可从https://github.com/umarkarim/cou_sfm和https://github.com/umarkarim/cou_stereo获得。

Diabetic Retinopathy (DR) is considered one of the primary concerns due to its effect on vision loss among most people with diabetes globally. The severity of DR is mostly comprehended manually by ophthalmologists from fundus photography-based retina images. This paper deals with an automated understanding of the severity stages of DR. In the literature, researchers have focused on this automation using traditional machine learning-based algorithms and convolutional architectures. However, the past works hardly focused on essential parts of the retinal image to improve the model performance. In this paper, we adopt transformer-based learning models to capture the crucial features of retinal images to understand DR severity better. We work with ensembling image transformers, where we adopt four models, namely ViT (Vision Transformer), BEiT (Bidirectional Encoder representation for image Transformer), CaiT (Class-Attention in Image Transformers), and DeiT (Data efficient image Transformers), to infer the degree of DR severity from fundus photographs. For experiments, we used the publicly available APTOS-2019 blindness detection dataset, where the performances of the transformer-based models were quite encouraging.

This paper presents our solutions for the MediaEval 2022 task on DisasterMM. The task is composed of two subtasks, namely (i) Relevance Classification of Twitter Posts (RCTP), and (ii) Location Extraction from Twitter Texts (LETT). The RCTP subtask aims at differentiating flood-related and non-relevant social posts while LETT is a Named Entity Recognition (NER) task and aims at the extraction of location information from the text. For RCTP, we proposed four different solutions based on BERT, RoBERTa, Distil BERT, and ALBERT obtaining an F1-score of 0.7934, 0.7970, 0.7613, and 0.7924, respectively. For LETT, we used three models namely BERT, RoBERTa, and Distil BERTA obtaining an F1-score of 0.6256, 0.6744, and 0.6723, respectively.

Objective: Despite numerous studies proposed for audio restoration in the literature, most of them focus on an isolated restoration problem such as denoising or dereverberation, ignoring other artifacts. Moreover, assuming a noisy or reverberant environment with limited number of fixed signal-to-distortion ratio (SDR) levels is a common practice. However, real-world audio is often corrupted by a blend of artifacts such as reverberation, sensor noise, and background audio mixture with varying types, severities, and duration. In this study, we propose a novel approach for blind restoration of real-world audio signals by Operational Generative Adversarial Networks (Op-GANs) with temporal and spectral objective metrics to enhance the quality of restored audio signal regardless of the type and severity of each artifact corrupting it. Methods: 1D Operational-GANs are used with generative neuron model optimized for blind restoration of any corrupted audio signal. Results: The proposed approach has been evaluated extensively over the benchmark TIMIT-RAR (speech) and GTZAN-RAR (non-speech) datasets corrupted with a random blend of artifacts each with a random severity to mimic real-world audio signals. Average SDR improvements of over 7.2 dB and 4.9 dB are achieved, respectively, which are substantial when compared with the baseline methods. Significance: This is a pioneer study in blind audio restoration with the unique capability of direct (time-domain) restoration of real-world audio whilst achieving an unprecedented level of performance for a wide SDR range and artifact types. Conclusion: 1D Op-GANs can achieve robust and computationally effective real-world audio restoration with significantly improved performance. The source codes and the generated real-world audio datasets are shared publicly with the research community in a dedicated GitHub repository1.

Uncertainty quantification is crucial to inverse problems, as it could provide decision-makers with valuable information about the inversion results. For example, seismic inversion is a notoriously ill-posed inverse problem due to the band-limited and noisy nature of seismic data. It is therefore of paramount importance to quantify the uncertainties associated to the inversion process to ease the subsequent interpretation and decision making processes. Within this framework of reference, sampling from a target posterior provides a fundamental approach to quantifying the uncertainty in seismic inversion. However, selecting appropriate prior information in a probabilistic inversion is crucial, yet non-trivial, as it influences the ability of a sampling-based inference in providing geological realism in the posterior samples. To overcome such limitations, we present a regularized variational inference framework that performs posterior inference by implicitly regularizing the Kullback-Leibler divergence loss with a CNN-based denoiser by means of the Plug-and-Play methods. We call this new algorithm Plug-and-Play Stein Variational Gradient Descent (PnP-SVGD) and demonstrate its ability in producing high-resolution, trustworthy samples representative of the subsurface structures, which we argue could be used for post-inference tasks such as reservoir modelling and history matching. To validate the proposed method, numerical tests are performed on both synthetic and field post-stack seismic data.

In recent years distributional reinforcement learning has produced many state of the art results. Increasingly sample efficient Distributional algorithms for the discrete action domain have been developed over time that vary primarily in the way they parameterize their approximations of value distributions, and how they quantify the differences between those distributions. In this work we transfer three of the most well-known and successful of those algorithms (QR-DQN, IQN and FQF) to the continuous action domain by extending two powerful actor-critic algorithms (TD3 and SAC) with distributional critics. We investigate whether the relative performance of the methods for the discrete action space translates to the continuous case. To that end we compare them empirically on the pybullet implementations of a set of continuous control tasks. Our results indicate qualitative invariance regarding the number and placement of distributional atoms in the deterministic, continuous action setting.
