全球越来越多的大学将各种形式的在线学习和混合学习作为其学术课程的一部分。此外，由于199年大流行而造成的最新变化导致在线教育的重要性和无处不在。电子学习的主要优点之一不仅是改善学生的学习经验并扩大教育前景，而且还可以通过学习分析来洞悉学生的学习过程。这项研究有助于通过以下方式改善和理解电子学习过程的主题。首先，我们证明可以根据从学生的行为数据中得出的顺序模式来构建准确的预测模型，这些模式能够在课程的早期识别出表现不佳的学生。其次，我们通过研究是否应根据特定于课程的顺序模式或基于更一般的行为模式的几个课程来构建每个课程的预测模型，从而调查了建立此类预测模型的特异性征用性权衡。最后，我们提出了一种捕获行为数据中时间方面的方法，并分析了其对模型预测性能的影响。我们改进的序列分类技术的结果能够以高度准确性来预测学生的表现，而对于课程特异性模型的结果达到了90％。

The rapidly evolving industry demands high accuracy of the models without the need for time-consuming and computationally expensive experiments required for fine-tuning. Moreover, a model and training pipeline, which was once carefully optimized for a specific dataset, rarely generalizes well to training on a different dataset. This makes it unrealistic to have carefully fine-tuned models for each use case. To solve this, we propose an alternative approach that also forms a backbone of Intel Geti platform: a dataset-agnostic template for object detection trainings, consisting of carefully chosen and pre-trained models together with a robust training pipeline for further training. Our solution works out-of-the-box and provides a strong baseline on a wide range of datasets. It can be used on its own or as a starting point for further fine-tuning for specific use cases when needed. We obtained dataset-agnostic templates by performing parallel training on a corpus of datasets and optimizing the choice of architectures and training tricks with respect to the average results on the whole corpora. We examined a number of architectures, taking into account the performance-accuracy trade-off. Consequently, we propose 3 finalists, VFNet, ATSS, and SSD, that can be deployed on CPU using the OpenVINO toolkit. The source code is available as a part of the OpenVINO Training Extensions (https://github.com/openvinotoolkit/training_extensions}

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.

学习贝叶斯网络是一个NP硬性问题，并且随着节点的数量增加，学习贝叶斯网络结构的经典算法效率低下。近年来，开发了一些用于学习大量节点的贝叶斯网络的方法和算法（超过50个）。但是，这些解决方案的缺点，例如，它们仅操作一种类型的数据（离散或连续），或者已经创建了其算法来满足数据的特定性质（医学，社交等）。本文介绍了一种用于学习具有大量节点（超过100个）的大型贝叶斯网络的大bravebn算法。该算法利用了勇敢的系数，该系数测量了几组实例的相互发生。为了形成这些组，我们根据共同信息（MI）度量使用最近的邻居方法。在本文的实验部分中，我们将BigBraveBN与其他现有解决方案的性能与多个离散和连续数据集进行了比较。实验部分还代表了对实际数据的测试。上述实验结果证明了Bigbravebn算法在贝叶斯网络的结构学习中的效率。
