肥胖是现代社会的严重问题，因为它与生活质量大大降低了。目前进行的研究是为了探索使用脑电图（EEG）数据探索与肥胖相关的神经学证据。在这项研究中，我们开发了一种新型的机器学习模型，以使用来自EEG数据的Alpha带功能连接功能来鉴定肥胖女性的大脑网络。总体分类精度达到90％。我们的发现表明，肥胖的大脑的特征是功能失调的网络，在该网络中，负责处理自指信息（例如能量需求）的领域受到损害。

在本文中，我们考虑了通过风险最小化监督学习中变异模型的问题。我们的目标是通过双层优化和通过算法展开对学习变异模型的两种方法进行更深入的了解。前者将变分模型视为低于风险最小化问题的较低级别优化问题，而后者将较低级别优化问题替换为解决上述问题的算法。两种方法都在实践中使用，但是从计算的角度来看，展开要简单得多。为了分析和比较两种方法，我们考虑了一个简单的玩具模型，并明确计算所有风险和各自的估计器。我们表明，展开可能比双重优化方法更好，而且展开的性能可以显着取决于进一步的参数，有时会以意外的方式：虽然展开的算法的步骤大小很重要，但展开的迭代数量只有很重要如果数字是偶数或奇数，并且这两种情况截然不同。

无放射治疗器官轮廓的深度学习模型是临床用途，但目前，预测轮廓的自动化质量评估（QA）有很多工具。使用贝叶斯模型及其相关的不确定性，可以自动化检测不准确预测的过程。我们使用定量测量 - 预期的校准误差（ECE）和基于定性的测量区域的精确度（R-AVU）图来调查两个贝叶斯模型进行自动轮廓众所周知，模型应该具有低欧洲欧洲经委会被认为是值得信赖的。然而，在QA语境中，模型也应该在不准确的区域中具有高不确定性，并且在准确的区域中的不确定性低。此类行为可以直接对专家用户的视觉关注潜在地不准确的地区，导致QA过程中的加速。使用R-AVU图表，我们定性地比较了不同模型的行为准确和不准确的地区。使用三种型号在Miccai2015头和颈部分割挑战和DeepMindtcia CT数据集上进行实验：丢弃骰子，辍学-CE（交叉熵）和Flipout-Ce。定量结果表明，丢弃骰子具有最高的ECE，而辍学-CE和FLIPOUT-CE具有最低的ECE。为了更好地了解辍学-CE和Flipout-CE之间的差异，我们使用R-AVU图表，显示Flipout-CE在不准确的地区具有比Dropout-Ce更好的不确定性覆盖率。定量和定性度量的这种组合探讨了一种新方法，有助于选择哪种模型可以在临床环境中作为QA工具部署。

Advances in computer vision and machine learning techniques have led to significant development in 2D and 3D human pose estimation from RGB cameras, LiDAR, and radars. However, human pose estimation from images is adversely affected by occlusion and lighting, which are common in many scenarios of interest. Radar and LiDAR technologies, on the other hand, need specialized hardware that is expensive and power-intensive. Furthermore, placing these sensors in non-public areas raises significant privacy concerns. To address these limitations, recent research has explored the use of WiFi antennas (1D sensors) for body segmentation and key-point body detection. This paper further expands on the use of the WiFi signal in combination with deep learning architectures, commonly used in computer vision, to estimate dense human pose correspondence. We developed a deep neural network that maps the phase and amplitude of WiFi signals to UV coordinates within 24 human regions. The results of the study reveal that our model can estimate the dense pose of multiple subjects, with comparable performance to image-based approaches, by utilizing WiFi signals as the only input. This paves the way for low-cost, broadly accessible, and privacy-preserving algorithms for human sensing.

Due to the environmental impacts caused by the construction industry, repurposing existing buildings and making them more energy-efficient has become a high-priority issue. However, a legitimate concern of land developers is associated with the buildings' state of conservation. For that reason, infrared thermography has been used as a powerful tool to characterize these buildings' state of conservation by detecting pathologies, such as cracks and humidity. Thermal cameras detect the radiation emitted by any material and translate it into temperature-color-coded images. Abnormal temperature changes may indicate the presence of pathologies, however, reading thermal images might not be quite simple. This research project aims to combine infrared thermography and machine learning (ML) to help stakeholders determine the viability of reusing existing buildings by identifying their pathologies and defects more efficiently and accurately. In this particular phase of this research project, we've used an image classification machine learning model of Convolutional Neural Networks (DCNN) to differentiate three levels of cracks in one particular building. The model's accuracy was compared between the MSX and thermal images acquired from two distinct thermal cameras and fused images (formed through multisource information) to test the influence of the input data and network on the detection results.

The advances in Artificial Intelligence are creating new opportunities to improve lives of people around the world, from business to healthcare, from lifestyle to education. For example, some systems profile the users using their demographic and behavioral characteristics to make certain domain-specific predictions. Often, such predictions impact the life of the user directly or indirectly (e.g., loan disbursement, determining insurance coverage, shortlisting applications, etc.). As a result, the concerns over such AI-enabled systems are also increasing. To address these concerns, such systems are mandated to be responsible i.e., transparent, fair, and explainable to developers and end-users. In this paper, we present ComplAI, a unique framework to enable, observe, analyze and quantify explainability, robustness, performance, fairness, and model behavior in drift scenarios, and to provide a single Trust Factor that evaluates different supervised Machine Learning models not just from their ability to make correct predictions but from overall responsibility perspective. The framework helps users to (a) connect their models and enable explanations, (b) assess and visualize different aspects of the model, such as robustness, drift susceptibility, and fairness, and (c) compare different models (from different model families or obtained through different hyperparameter settings) from an overall perspective thereby facilitating actionable recourse for improvement of the models. It is model agnostic and works with different supervised machine learning scenarios (i.e., Binary Classification, Multi-class Classification, and Regression) and frameworks. It can be seamlessly integrated with any ML life-cycle framework. Thus, this already deployed framework aims to unify critical aspects of Responsible AI systems for regulating the development process of such real systems.
