Automatic Text Summarization (ATS) is becoming relevant with the growth of textual data; however, with the popularization of public large-scale datasets, some recent machine learning approaches have focused on dense models and architectures that, despite producing notable results, usually turn out in models difficult to interpret. Given the challenge behind interpretable learning-based text summarization and the importance it may have for evolving the current state of the ATS field, this work studies the application of two modern Generalized Additive Models with interactions, namely Explainable Boosting Machine and GAMI-Net, to the extractive summarization problem based on linguistic features and binary classification.

This work presents a thorough review concerning recent studies and text generation advancements using Generative Adversarial Networks. The usage of adversarial learning for text generation is promising as it provides alternatives to generate the so-called "natural" language. Nevertheless, adversarial text generation is not a simple task as its foremost architecture, the Generative Adversarial Networks, were designed to cope with continuous information (image) instead of discrete data (text). Thus, most works are based on three possible options, i.e., Gumbel-Softmax differentiation, Reinforcement Learning, and modified training objectives. All alternatives are reviewed in this survey as they present the most recent approaches for generating text using adversarial-based techniques. The selected works were taken from renowned databases, such as Science Direct, IEEEXplore, Springer, Association for Computing Machinery, and arXiv, whereas each selected work has been critically analyzed and assessed to present its objective, methodology, and experimental results.

Machine Learning algorithms have been extensively researched throughout the last decade, leading to unprecedented advances in a broad range of applications, such as image classification and reconstruction, object recognition, and text categorization. Nonetheless, most Machine Learning algorithms are trained via derivative-based optimizers, such as the Stochastic Gradient Descent, leading to possible local optimum entrapments and inhibiting them from achieving proper performances. A bio-inspired alternative to traditional optimization techniques, denoted as meta-heuristic, has received significant attention due to its simplicity and ability to avoid local optimums imprisonment. In this work, we propose to use meta-heuristic techniques to fine-tune pre-trained weights, exploring additional regions of the search space, and improving their effectiveness. The experimental evaluation comprises two classification tasks (image and text) and is assessed under four literature datasets. Experimental results show nature-inspired algorithms' capacity in exploring the neighborhood of pre-trained weights, achieving superior results than their counterpart pre-trained architectures. Additionally, a thorough analysis of distinct architectures, such as Multi-Layer Perceptron and Recurrent Neural Networks, attempts to visualize and provide more precise insights into the most critical weights to be fine-tuned in the learning process.

需要在机器学习模型中对最小参数设置的需求，以避免耗时的优化过程。$ k $ - 最终的邻居是在许多问题中使用的最有效，最直接的模型之一。尽管具有众所周知的性能，但它仍需要特定数据分布的$ K $值，从而需要昂贵的计算工作。本文提出了一个$ k $ - 最终的邻居分类器，该分类器绕过定义$ k $的值的需求。考虑到训练集的数据分布，该模型计算$ k $值。我们将提出的模型与标准$ K $ - 最近的邻居分类器和文献中的两个无参数版本进行了比较。11个公共数据集的实验证实了所提出方法的鲁棒性，因为所获得的结果相似甚至更好。

本文提出了一种新型的多式模式自学架构，用于节能音频 - 视听（AV）语音增强，将图形神经网络与规范相关性分析（CCA-GNN）集成在一起。所提出的方法将其基础放在最先进的CCA-GNN上，该方法通过最大化相同输入的增强视图对之间的相关性来学习代表性的嵌入，同时脱离了断开连接的特征。常规CCA-GNN的关键思想涉及丢弃增强变化的信息并保留增强不变的信息，同时阻止捕获冗余信息。我们提出的AV CCA-GNN模型涉及多模式表示学习环境。具体而言，我们的模型通过从音频和视觉嵌入的同一信道和规范相关性的增强视图中最大化的规范相关性来改善上下文AV语音处理。此外，它提出了一个位置节点编码，该位置节点在计算节点最近的邻居时考虑了先前的框架序列距离，而不是特征空间表示，并通过邻域的连接在嵌入式中引入时间信息。在基准Chime3数据集上进行的实验表明，我们提出的基于框架的AV CCA-GNN确保在时间上下文中获得更好的特征学习，从而导致比最先进的CCA-GNN更节能的语音重建感知器（MLP）和长期记忆（LSTM）模型。

通常，基于生物谱系的控制系统可能不依赖于各个预期行为或合作适当运行。相反，这种系统应该了解未经授权的访问尝试的恶意程序。文献中提供的一些作品建议通过步态识别方法来解决问题。这些方法旨在通过内在的可察觉功能来识别人类，尽管穿着衣服或配件。虽然该问题表示相对长时间的挑战，但是为处理问题的大多数技术存在与特征提取和低分类率相关的几个缺点，以及其他问题。然而，最近的深度学习方法是一种强大的一组工具，可以处理几乎任何图像和计算机视觉相关问题，为步态识别提供最重要的结果。因此，这项工作提供了通过步态认可的关于生物识别检测的最近作品的调查汇编，重点是深入学习方法，强调他们的益处，暴露出弱点。此外，它还呈现用于解决相关约束的数据集，方法和体系结构的分类和表征描述。

使用卷积神经网络（CNN）已经显着改善了几种图像处理任务，例如图像分类和对象检测。与Reset和Abseralnet一样，许多架构在创建时至少在一个数据集中实现了出色的结果。培训的一个关键因素涉及网络的正规化，这可以防止结构过度装备。这项工作分析了在过去几年中开发的几种正规化方法，显示了不同CNN模型的显着改进。该作品分为三个主要区域：第一个称为“数据增强”，其中所有技术都侧重于执行输入数据的更改。第二个，命名为“内部更改”，旨在描述修改神经网络或内核生成的特征映射的过程。最后一个称为“标签”，涉及转换给定输入的标签。这项工作提出了与关于正则化的其他可用调查相比的两个主要差异：（i）第一个涉及在稿件中收集的论文并非超过五年，并第二个区别是关于可重复性，即所有作品此处推荐在公共存储库中可用的代码，或者它们已直接在某些框架中实现，例如Tensorflow或Torch。

本文介绍了一个模糊认知地图模型，用于量化结构化数据集中的隐式偏置，其中特征可以是数字或离散的。在我们的建议中，问题特征被映射到在运行什么时专家最初由专家激活的神经概念，而连接神经概念的权重表示特征之间的绝对相关/关联模式。此外，我们介绍一种配备的新推理机制，配备有标准化的转移功能，可防止神经元饱和。这种新推理机制的另一个优点是它可以通过在更新每个迭代中的神经元激活值时来调节非线性来容易地控制。最后，我们研究了我们模型的融合和源于定点吸引子的存在和单性的分析条件。

深度学习（DL）是各种计算机视觉任务中使用的主要方法，因为它在许多任务上取得了相关结果。但是，在具有部分或没有标记数据的实际情况下，DL方法也容易出现众所周知的域移位问题。多源无监督的域适应性（MSDA）旨在通过从一袋源模型中分配弱知识来学习未标记域的预测指标。但是，大多数作品进行域适应性仅利用提取的特征并从损失函数设计的角度降低其域的转移。在本文中，我们认为仅基于域级特征处理域移动不足，但是在功能空间上对此类信息进行对齐也是必不可少的。与以前的工作不同，我们专注于网络设计，并建议将多源版本的域对齐层（MS-DIAL）嵌入预测变量的不同级别。这些层旨在匹配不同域之间的特征分布，并且可以轻松地应用于各种MSDA方法。为了显示我们方法的鲁棒性，我们考虑了两个具有挑战性的情况：数字识别和对象分类，进行了广泛的实验评估。实验结果表明，我们的方法可以改善最新的MSDA方法，从而在其分类精度上获得 +30.64％的相对增长。

Video segmentation consists of a frame-by-frame selection process of meaningful areas related to foreground moving objects. Some applications include traffic monitoring, human tracking, action recognition, efficient video surveillance, and anomaly detection. In these applications, it is not rare to face challenges such as abrupt changes in weather conditions, illumination issues, shadows, subtle dynamic background motions, and also camouflage effects. In this work, we address such shortcomings by proposing a novel deep learning video segmentation approach that incorporates residual information into the foreground detection learning process. The main goal is to provide a method capable of generating an accurate foreground detection given a grayscale video. Experiments conducted on the Change Detection 2014 and on the private dataset PetrobrasROUTES from Petrobras support the effectiveness of the proposed approach concerning some state-of-the-art video segmentation techniques, with overall F-measures of $\mathbf{0.9535}$ and $\mathbf{0.9636}$ in the Change Detection 2014 and PetrobrasROUTES datasets, respectively. Such a result places the proposed technique amongst the top 3 state-of-the-art video segmentation methods, besides comprising approximately seven times less parameters than its top one counterpart.
